Michigan Highways Master List: 1913–Present

The Michigan Highways Master List is a complete catalogue of every state trunkline (I, US, and M) and Intercounty highway (A- through H-) route designation ever used in Michigan, from 1913 to today, including any auxiliary routes such as Alternate (ALT), Business (BUS), Business Loop (BL), Business Spur (BS), Bypass (BYP) Connector (CONN), Spur (SPUR), Temporary (TEMP) and Truck (TRK) routes and even a few archaic designations such as Extension (EXT) and Stub (STUB). This list was concieved out of many requests for information on route designations no longer in use, such as "Was there ever an M-41?" or "I heard about an ALTERNATE US-23. Was there such a thing?"

This page lists each designation in numerical order, from 1 through 696 followed by the Intercounty Highways, and is separated into listings generally corresponding to the initial setup of this website (e.g. 1-9, 10-19, etc.) for easier reference. Five 'types' of designations are included: current, unsigned, future and former routes, as well as those which have never been used to date. Each is color-coded, as shown in the "Highway Status Key" below. Current and Future route designations include a link to the regular listing on the website. The few Unsigned routes are also linked to a listing on the website. For those Formerly-Used designations, a short description of the former route is included for referencial purposes unless a Former Route Listing exists. Also included are route designations which were Planned But Never Implemented, for any number of possible reasons. Never-Used designations, of course, feature no description, as they have never existed in the system. The "Extant" column indicates the timeframe the route designation was in use.

With an undertaking of this magnitude, there may be a designation or two which have been overlooked or mis-stated. I have combed through thousands of sources and many hundreds of old road and street maps, so the information contained on this page is reasonably complete and accurate. However, if you should find any information which is incorrect, or if you know of a designation which has not been included here, please drop me a line at chris.bessert@gmail.com.

US-2A FMR 1933—1939 The original designation for what became M-54 through downtown Ironwood (1939–1942), which was then redesignated as BUS US-2.
US-2A FMR 1931—1935 An alternate route for US-2 following a former alignment of US-2/US-41/M-35 north out of Escanaba via Wells which actually functioned more like a Business Route than an Alternate Route, but as Business Routes didn't debut in Michigan until c.1939 at the earliest, the MSHD used the "A" designation most of the time. (See Ironwood example above... and below!) The route itself was shown on official highway maps, but it was never labeled. Internal MSHD maps did label it, though, as did at least one 1933 AAA road map as well. (The 1932 USGS Topographic map for the area also lists this route as "US-2A & US-41A" implying both routes were signed as alternates here.)
US-2 BUS CUR 1942—Now IRONWOOD: BUS US-2 Listing
US-2 BUS P/NU c.1958 ST IGNACE: From internal State Highway Dept documents, the department was planning on designating the existing route of US-2 through St Ignace as a concurrent BL I-75/BUS US-2 once the I-75 freeway bypassing St Ignace was completed and opened to traffic. It seems unlikely any BUS US-2 route marker assemblies were ever posted along BL I-75 when that route debuted.
US-2 STUB FMR 1929—1937 A short, 0.4-mile long spur route from then-US-2 (present-day M-129/M-48) in downtown Pickford along Main St to 125 ft east of Manila Rd. Likely an unsigned trunkline. (No evidence any of the STUB routes were ever signed in the field.)
M-2 FMR 1970s Temporary, unsigned route designation used along the I-96/Jeffries Frwy services drives as the freeway was under construction in the early- to mid-1970s.
M-2 P/NU 1990s Proposed for a freeway or arterial connecting highway running between I-275 and I-75 south of Detroit Metropolitan Airport in Wayne Co in the late-1980s or early-1990s, possibly with an extension to the west to US-23 south of Ann Arbor. The highway was never constructed.

US-10 BUS FMR c1940—1962 FLINT: Originally the route of US-10 through downtown Flint, later designated M-10, then given the BUS US-10 designation when Business routes debuted in Michigan around 1940. Replaced by BUS M-54, now a locally-maintained street.
US-10 BUS P/NU 1959 FLINT: From internal State Highway Dept maps and documents, what eventually became I-475 through Flint was initially given the BUS US-10 designation. Once the Interstate route designations were finalized between the State Highway Dept and the federal government, the proposed freeway loop through downtown Flint became I-475.
US-10 BUS FMR 1961—1986 PONTIAC: Originally US-10 throughthe center of Pontiac, designated BUS US-10 when US-10 replaced M-58. Now designated BUS US-24.
US-10 BUS P/NU 1953

SAGINAW: From internal State Highway Dept maps and documents, what eventually became I-675 through Saginaw was initially given the BUS US-10 designation. Once the Interstate route designations were finalized between the State Highway Dept and the federal government, the proposed freeway loop through downtown Saginaw became I-675. An even earlier proposal had been put forth in 1953 with a BUS US-10 routing using one-way pairs of streets to loop through the northern portion of the city, again along the general corridor which later became I-675.
US-10 CONN FMR 1961—1975 The unsigned freeway connector between US-10 and US-27 east of Clare completed in 1961. Until the US-10/M-115 bypass of Clare and Farwell was completed in 1975, US-10 traveled along present-day BUS US-10 into downtown Clare, thus the segment of present-day US-10 between present-day Exits 98 and 158 was officially designated CONN US-10 south-to-eastbound and as CONN US-27 for west-to-northound traffic. Likely signed "TO US-10" in the eastbound direction (and "TO US-27" westbound).
US-10 TEMP P/NU 1969 When US-10 was removed from the Woodward Ave alignment between Detroit and Pontiac and transferred to the route of the John C Lodge Frwy and US-24/Telegraph Rd, AASHO specified the "overlap" of US-10 and US-24 along Telegraph Rd be signed as TEMPORARY US-10. There is no evidence any "TEMP" signs were ever used along this route and it was always signed as simply part of US-10 from 1970–1986.

US-12A FMR c1931–1937? An alternate routing for US-12 through the central part of Saint Joseph, running along Lake Blvd from Lakeshore Dr northerly to Ship St, then easterly along Ship to a terminus at US-12/US-31 at the cnr of Ship & Main Sts. Turned back to city control on Dec 29, 1937. (Thanks for bugging me, Marc...)
US-12A FMR 1930—1956 Original route of US-12 along Michigan Ave between Kalamazoo and Comstock. Was decommissioned when M-96 replaced US-12 in this area. Route markers may have been removed from this route as early as 1954, but the highway itself was turned back to local control in 1956.
US-12A FMR 1941-ish Original route designation of the "Fort Custer Highway" being built by the State Hwy Dept through Fort Custer, generally along the approximate route of the former US-12 alignment through the area. The US-12A designation doesn't seem to have ever been applied to the route, though.
US-12A FMR 1936—c1939 Original route of US-12 through downtown Battle Creek, designated as US-12A when US-12 bypassed the city center. Later designated BUS US-12.

US-12 BUS FMR 1957—c1960 KALAMAZOO: When the US-12 freeway was completed around Kalamazoo, the former route through downtown Kalamazoo was designated BUS US-12 for a time. Later changed to BL I-94.
US-12 BUS FMR c1939—1960 BATTLE CREEK: Mostly replaced the US-12A routing through downtown Battle Creek. Removed when I-94/US-12 freeway was completed south of Battle Creek.
US-12 BUS FMR 1960 MARSHALL: Was designated for a short time before being replaced by BL I-94.
US-12 BUS FMR 1960 ALBION: Was designated for a short time before being replaced by BL I-94.
US-12 BUS FMR 1951—1960 JACKSON: Was designated along much of the former route of US-12 through downtown when the US-12 "Jackson Bypass" was built in stages. Replaced by the current BL I-94 designation.
US-12 BUS FMR ? ANN ARBOR: Potentially-signed soon after the completion of I-94/US-12 around the city, but if it was signed as BUS US-12, it was converted to BL I-94 soon after.
M-12 FMR 1913—1927 The pre-1926 designation of much of US-2 through the Upper Peninsula, from Ironwood to Sault Ste. Marie, with the exception of the portion from Crystal Falls to Sagola (now M-69) and Sagola to Iron Mountain (now M-95).

M-13 SPUR FMR 1931 The initial designation for what was later (likely) signed as part of M-79 and then M-214 from Nashville to Vermontville. It was designated as such temporarily and assumedly never signed as such in the field, since its parent route, M-13, was also changed to M-14 likely before it was signed in the field between Battle Creek and Six Lakes in 1931.

M-14 BUS P/NU c.1965 From internal State Highway Dept documents, it appears the department was planning on designating a BUS M-14 route at Ann Arbor once the Ann Arbor "North Belt" freeway was opened. Unlike the proposed M-114 routing, BUS M-14 was shown as beginning at the eastern M-14 & US-23 jct then continuing southerly via US-23 to Plymouth Rd (the former M-14 routing), then following Plymouth Rd and Broadway from US-23 into downtown Ann Arbor. It would then turn southerly with BUS US-23 along N Main St, then follow BL I-94/Huron St westerly to I-94 on the west side of Ann Arbor. As with the proposed M-114 designation, it appears BUS M-14 was also never signed, as Plymouth Rd and Broadway within the City of Ann Arbor was transferred to city control within months of the opening of the M-14 "North Belt" freeway bypass.
M-14 SPUR FMR 1931–1935 A 1.8-mile spur route in Barry Co along Assyria Rd connecting M-14 at the cnr of Assyria Rd & Lawrence Rd with M-79/Scott Rd to the north. Supplanted by a rerouted M-79 in early 1935.
M-14 SPUR FMR 1931 After initially being designated as M-13 SPUR before its parent route was quickly redesignated as M-14, the M-14 SPUR from Nashville to Vermontville was likely signed as part of M-79 for several years until being designated as M-214 for several years.

US-16A FMR c1933—1957 FARMINGTON: Designation for the "Farmington Cut-Off," a one-way bypass around the City of Farmington.
US-16 ALT FMR c.1940—1941 GRAND HAVEN: In the early 1940s, after US-16 was relocated onto the direct route between Nunica and Muskegon, the former route via M-104 and US-31 was designated ALT US-16 for a short time.
US-16 BUS FMR 1953—1962 GRAND RAPIDS: When US-16 was transferred onto the southern and western bypass of Grand Rapids (the former BYP US-16) in 1953, the former route of US-16 through downtown Grand Rapids was designated BUS US-16.
US-16 BUS P/NU 1958 HOWELL: From internal State Highway Dept maps and documents, what eventually became BL I-96 through Howell was initially given the BUS US-16 designation. Never signed as BUS US-16, as the US-16 designation was removed from the state upon completion of I-96 from Brighton, past Howell to the Lansing area. This route has always been signed as BL I-96.
US-16 BUS FMR 1957—1961 FARMINGTON: For many years, the "Farmington Cut-Off" (now the M-5 freeway) was for eastbound traffic only, meaning the original route of US-16 along Grand River Ave through downtown Farmington retained the "official" routing of US-16. Later, when the "Cut-Off" was opened to two-way traffic and US-16 transferred to it, the former route of US-16 through Farmington was designated BUS US-16. Replaced by BL I-96 in the 1960s, now an unsigned state highway.
US-16 BYP FMR 1942—1953 GRAND RAPIDS: When originally constructed, the "Grand Rapids Beltline System" was designated M-114. Later in 1942, the southern and western legs were given the BYP US-16 designation as an alternate route around downtown Grand Rapids. Then in 1953, given the mainline US-16 designation, now designated M-11.
M-16 FMR 1913—1927 Ironically, what was to become US-16 in 1926 was originally designated M-16 in 1918. Ran along the present I-96 corridor from Grand Haven through Grand Rapids and Lansing, ending in Detroit.
M-17 CUR 1913—Now M-17 Listing
M-17 BUS FMR 1944—1956 YPSILANTI: When the BYP US-112 freeway opened around the south side of Ypsilanti (now I-94/US-12) in August 1944, M-17 was transferred to that route and the original route of M-17 through downtown Ypsilanti along Ecorse Rd, Michigan Ave and Washtenaw Ave was designated BUS M-17. Now designated M-17.
US-18 P/NU 1926 Under the first iteration of the US Highway system as laid out in 1926, the route which would eventually become US-16 from Detroit through Howell, Lansing, Portland, Grand Rapids to Grand Haven was originally assigned the US-18 designation. (In this early iteration, US-10 was to be designated US-12, US-12 was given the US-10 designation, and US-112 was designated US-110.) In the final US Highway system approved by AASHO in 1927, thoiugh, US-18 was instead designated as US-17, which interestingly had been previously designated as M-16 throughout Michigan.

M-21A FMR c.1933? The intial (or initially proposed) designation for M-210, the former route of M-21 through Pewamo in eastern Ionia Co.
M-21A FMR 1929—1949 A parallel route to M-21 along Lapeer Rd from US-10/Dort Hwy (now M-54) to M-15 at Davison. Likely utilized short sections of US-10 and M-15 to connect back with M-21 at either end. Now a locally-maintained road.
M-21 BUS FMR 1953—1974 GRAND RAPIDS: When the M-21 desingation was transferred onto the routing of BYP M-21 around Grand Rapids, the former route of M-21 through the City of Grand Rapids was designated BUS M-21. While the eastern half of this route is now a locally-maintained street, the western half became BS I-196.
M-21 BYP FMR 1944—1953 GRAND RAPIDS: When originally constructed, the "Grand Rapids Beltline System" was designated M-114. Later, the eastern and southern legs were given the BYP M-21 designation in 1944 as an alternate route around downtown Grand Rapids. Then given the primary M-21 designation in 1953, now designated as parts of M-37 and M-11.
M-21 CONN FMR 1972—2004? GRAND RAPIDS: A short connector route between M-37/M-44/East Beltline Ave and M-21 at I-96 Exit 39 from when M-21 continued westerly along I-96 and then I-196 through Grand Rapids and then via Chicago Dr through Hudsonville to Holland. When M-21 was truncated back to I-96 at Exit 39 in 1974, evidence points to CONN M-21 existing possibly until as late as 2004 until it was incorporated into the route of mainline M-21 and decommissioned.
M-21 STUB FMR 1929—1934? Initially a spur route from M-21 in downtown Lyons travelling northerly for 1.4 miles into downtown Muir, once the new route of M-21 was completed on the north side of the Grand River between Ionia and Pewamo in 1931, M-21 STUB simply "reversed" and became a spur route from M-21 at Muir heading southerly 1.4 miles into downtown Lyons (along the same, unchanged route). "M-21 STUB" is likely an internal, unsigned designation. The spur is labeled as M-166 on official highway maps beginning in 1934 and that route is extended from Lyons to Portland a year later.

M-22A NEV A tourist map published in the 1950s titled "Leelanau County The Land of Delight Cool Tourism Map" featured a map of Leelanau Co with the state trunklines and numbered county routes depicted. The map shows Co Rd 633 (Cherry Bend Rd and Center Hwy) between Greilickville and Suttons Bay as "M-22A" with state highway marker symbols, while this route was part of M-22 in the 1930s (south of Crain Hill Rd) and through the 1940s (Crain Hill Rd northerly), absolutely no evidence that this was ever designated as M-22A has been located. In fact, the Co Rd 633 alignment was turned back to local control on the same date as the new M-22 route closer to the Grand Traverse Bay shoreline was established. "M-22A" is included here as a never-used route designation in case others have questions on its existence.

US-23A FMR c.1967 The Michigan State Highway Dept originally designated M-13 from Kawkawlin to Standish as ALT US-23 when the current I-75/US-23 freeway was completed in 1967. MSHD actually posted the former US-23 as "ALT US-23," but when that designation was not approved by the AASHTO, the department gave in and extended the M-13 designation along the route.
US-23A FMR c1929—c1931 Another short-lived US-23A designation existed from c.1929-1930 when a new US-23 routing was built on the east shore of the Saginaw River between Saginaw and Bay City. The former route was designated US-23A for only a short time, assumedly since the AASHTO declined to okay this new designation. By 1931, US-23A had been redesignated as part of M-47.

US-23 BUS FMR 1941—1960 BAY CITY: When US-23 was routed out of downtown Bay City to run west along present M-84/Salzburg Ave and north along present M-13/Euclid Ave, the former route of US-23 through downtown Bay City was designated as BUS US-23. Now designated, in parts, as M-84 and M-25/BS I-75.

(This had been previously designated as US-25A.) Then, when the Detroit-Toledo Expressway was completed from the Ohio state line northerly past Monroe to the Woodhaven area of Wayne Co, it was designated US-24A. A few years later, US-24A was decommissioned in favor of the I-75 designation.

US-27A FMR 1930—1961 One of the earliest Alternate US Highways in the nation. The US-27 mainline ran northerly into St. Louis, while US-27A ran west into downtown Alma, then north back to US-27 west of St. Louis and north of Alma. When the US-27 freeway was completed at St. Louis and Alma in the 1960s, this US-27A routing was redesignated as BUS US-27, a "mirror-image" of St. Louis' BUS US-27.
US-27A FMR 1930—1939 When US-27 was moved to a bypass routing west of Shepherd along Federal Rd, the former route through Shepherd was designated US-27A. This designation was dropped in the 1930s and was never designated BUS US-27.
US-27 BUS FMR c1967 COLDWATER: When the I-69/US-27 freeway was completed past Coldwater in the late-1960s, a BUS US-27 designation may have commissioned concurrently with BL I-69—it was shown as such on some internal State Highway Dept maps. If it was actually signed in the field, this designation likely only survived a year or two at most.
US-27 BUS FMR c1967—1971 MARSHALL: When the I-69/US-27 freeway was completed west of Marshall in the late-1960s, a BUS US-27 designation was commissioned along Michigan Ave from I-69/US-27 easterly into downtown Marshall, then northerly along the former US-27 to I-94. This designation survived for several years before being removed.
US-27 BUS FMR 1961—1974 CHARLOTTE: The original routing of US-27 through downtown Charlotte, commissioned when the US-27 bypass was completed. Survived for a couple years after the coming of I-69, but was eventually replaced by the current BL I-69 routing.

US-27 CONN FMR 1961—1975 The unsigned freeway connector between US-10 and US-27 east of Clare completed in 1961. Until the US-10/M-115 bypass of Clare and Farwell was completed in 1975, US-10 traveled along present-day BUS US-10 into downtown Clare, thus the segment of present-day US-10 between present-day Exits 98 and 158 was officially designated CONN US-10 south-to-eastbound and as CONN US-27 for west-to-northound traffic. Likely signed "TO US-27" in the westbound direction (and "TO US-10" eastbound).
US-27 TRK FMR c1936—1950 For many years, there were two routings for US-27 and M-78 through downtown Lansing. The US-27/M-78 "Passenger Car Route" ran along Capitol Ave and Saginaw St. (This would be considered the "mainline" routing.) A US-27/M-78 "Truck Route" ran east on Main St, north on Grand Ave, east on Kalamazoo Ave and north on Larch St. TRUCK US-27/TRUCK M-78 was eventually replaced by the mainline US-27/M-78 when the Capitol Ave routing was given back to local control.

US-31A was the original downtown Muskegon bypass along Getty and Marquette Aves. Later, US-31 was transferred onto the US-31A alignment, and US-31A was moved onto the former US-31 routing through downtown Muskegon. US-31A was redesignated BUS US-31 in the 1940s, and retains that designation today.
US-31A FMR 1931—1937 As with Muskegon, US-31 was the orignal bypass of Ludington along Pere Marquette Rd, while US-31 continued to jog through downtown Ludington. Later replaced by the mainline US-31 routing.
US-31A FMR ? A purported "business" routing through downtown Beulah. US-31A was a very short highway running one block west of US-31, and likely an original routing of US-31 through the city. Now a locally-designated street.

US-31 BUS FMR c1963 ST. JOSEPH: Immediately after US-31 was transferred onto its current I-94 and I-96 (I-196) bypass routing around St. Joseph and Benton Harbor, the former route of US-31 through downtown St. Joseph was designated BUS US-31. (BUS US-31 was paired with US-33 throughout.) Another State Highway Dept map indicated the original plans for BUS US-31 to run concurrently with BL I-94 from downtown St Joseph, through Benton Harbor to a terminus at I-94/US-31 east of Benton Harbor. The BUS US-31 routing at St Joseph lasted for only about a year and the route became just US-33, now designated M-63.
US-31 BUS FMR 1942—1963 SOUTH HAVEN: When the original bypass of South Haven was completed in the 1940s, the former route of US-31 through downtown South Haven was designated BUS US-31. The southern half of this route is now part of BL I-196.

US-41 BUS P/NU 1966—1970 ISHPEMING/NEGAUNEE: Michigan State Highway Department officialls attempted on a few occasions between 1966 and 1970 to convince AASHO officials to allow them to add the BUS US-41 designation to the existing BUS M-28 routing at Ishpeming/Negaunee (or, possibly, to replace BUS M-28—that is somewhat unclear). The applications were denied by AASHO due to the existing railroad grade crossings and the level of railroad traffic at the time. With most of those crossings since eliminated, State officials have not attempted to add the BUS US-41 designation since 1970.
US-41 BUS FMR 1940—1957 BARAGA: The original route of US-41 through downtown Baraga, running from M-35/State St southerly along Superior St back to US-41 at the southern city limit. Existed from 1940 when the current US-41 was built bypassing the downtown area and was cancelled in mid-1957 and turned back to local control.
US-41 SPUR FMR 1929—1976 US-41 SPUR, although likely never signed as such in the field and being an internal MSHD designation, was the designation for the one-block long spur route along 15th St from US-41 to 10th Ave in Menominee.

The original I-67 was later swapped out for a northerly extension of I-69 from Indiana to Marshall. The Michigan State Highway Dept then suggested redesignating what was then part of I-96 from Benton Harbor past Holland to Grand Rapids (unbuilt from Holland to Grand Rapids) as I-69 while moving the I-96 designation to what was then I-196 between Grand Rapids and Muskegon. AASHO instead approved jsut flip-flopping the I-96 and I-196 designations, reserving I-67 for "future Interstate expansion"... which has yet to occur many decades later.

In 1973, the portion of the M-78 freeway from Morrice to Flint was redesignated as part of I-69 and all of M-78 from Charlotte to Morrice was redesignated as TEMPORARY I-69. The route of TEMP I-69 followed US-27 from Charlotte to I-96 southwest of Lansing, ran easterly on I-96 to I-496/US-127, then north on I-496 and US-127 to Saginaw Rd, then northeasterly out of the Lansing area, connecting to the I-69 freeway Morrice.
TEMP I-69 was cut into to pieces in 1987 when the portion of I-69 from I-96 southwest of Lansing in Eaton Co to Exit 94 north of Haslett in Clinton Co was designated as such. The portion of the former TEMP I-69 from US-127 to Exit 94 became part of a new BL I-69. The eastern segment of TEMP I-69 from Exit 94 to Morrice was replaced by a completed I-69 freeway in 1990, while the western segment of TEMP I-69 from Charlotte to I-96 was completely replaced by October 1992, when the final segment of I-69 was completed.

M-74 FMR 1920—1939 In 1920, M-74 existed as a "cut-off" route for M-14 (US-27's predecessor route) in Clare and Missaukee Counties. Beginning at M-14 north of Harrison, M-74 ran west to Leota, then northerly through Moddersville and Butterfield, ending at M-14 at Merritt. (During that time, M-14 bent west, then north from Houghton Lake to connect with M-13 south of Kalkaska, instead of continuing northerly past Houghton and Higgins Lakes toward Grayling.)
In 1923, M-14 was routed to the east of Houghton and Higgins Lakes on the later route of US-27. The former route of M-14 in Missaukee Co from Merrit northerly to Moorestown, then west to Pioneer was redesignated as an extension of M-74.All of M-74 south of Moddersville (via Leota to M-14 north of Harrison) was turned back to local control in 1925, making M-74 a spur-route south of Merritt. The southern spur from Merritt to Moddersville was removed in 1938, with the remainder of M-74 being removed in 1939.

I-94 CONN FMR 1971–c1998 This route existed along what was once Shook Rd from US-25/Gratiot Ave (today's M-3) southerly and was once part of the route of M-29 when it was rerouted onto the "Mount Clemens Bypass" in 1947 until I-94 was constructed atop much of this route in the early 1960s. When I-94 opened in this area in late 1963, the portion of former M-29/Snover Rd south of Hall Rd (CONN M-59) becomes a long, one-way on-ramp to wbd I-94, while the portion between Gratiot Ave and Hall Rd maintains its two-way traffic configuration. When all of M-29 south of 23 Mile Rd was lopped off in 1971, this segment of former M-29 along Snover Rd began to be shown on internal Dept of State Highways maps as CONN I-94, likely signed as "TO I-94" from Gratiot Ave. In 1998, the on-ramp section of this route south of Hall Rd was closed when a new Hall Rd/Wm P Rosso Hwy interchange opens at I-94 just to the east. In 2002, the remainder of former Snover Rd between M-3/Gratiot Ave and M-59/Hall Rd was obliterated and replaced by Marketplace Dr just to the east.

South Haven was earmarked to get an Interstate Business Connection, which would've been designated BL I-96. It is unknown if BL I-96 was signed as such, as I-96 past South Haven was redesignated as I-196 and, as such, the Business Connection at South Haven became BL I-196.

US-110 P/NU 1926 Under the first iteration of the US Highway system as laid out in 1926, the route which would eventually become US-112 from Detroit west-southwesterly through Ypsilanti, Saline, Jonesville, Coldwater, Sturgis, and White Pigeon and westerly was originally assigned the US-110 designation. This is because what eventually became US-12 between Detroit and Chicago (the modern-day I-94 corridor) was originally assigned the US-10 designation, thus the auxillary route was to be US-110. When the Detroit-Chicago route was designated US-12 in the final plan, US-110 was simply switched to US-112.

US-112 BUS FMR 1956—1962 YPSILANTI: In mid-1956, US-112 was transferred onto the Ypsilanti bypass routing (along with the addition of US-12) and the former route of US-112 through downtown Ypsilanti was designated BUS US-112. Upon US-112's removal from Michigan in 1961, BUS US-112 was redesignated BUS US-12.
US-112 BYP FMR 1944—1956 YPSILANTI: As an extension to the Willow Run Expwy system constructed during World War II, BYP US-112 was completed around the south side of Ypsilanti in August 1944. It was later designated as part of the US-112 mainline, then later US-12, as it is today. In mid-1956, US-112 was transferred onto the bypass routing (along with the addition of US-12) and the former route of US-112 through Ypsilanti was designated BUS US-112.
US-112S FMR c1933—1935 In c.1933, the portion of US-112 leading into Indiana was apparently designated "US-112S" in anticipation of Michigan extending the mainline of US-112 westerly via Niles to US-12 at New Buffalo. The short north-south segment of the highway leading into Indiana may have been designated "US-112S" in Michigan. US-112S was never officially approved by the AASHO (today's AASHTO) and said organization noted there was contention between Michigan and Indiana over the routing of US-112. US-112S may have been a way for Indiana to keep a "branch" of US-112 in its state after Michigan's anticipated rerouting of the mainline of US-112 directly west through Niles to New Buffalo. This route later bore the designation M-205 and is now a county road named "Old M-205.".

However, the part of the former M-14 along Plymouth Rd from M-153 southwesterly to Green Rd (just west of US-23) was turned back to county control the same day the new M-14 freeway was established as a state trunkline and the remainder of former M-14 along Plymouth Rd and Broadway into downtown Ann Arbor was turned back to the city a few months later, so it would appear the plans to designate this route as M-114 were never implemented.

M-132 FMR 1929—1960 M-132 was a spur-route trunkline linking Ann Arbor and Dexter via Dexter-Ann Arbor Rd from 1929 to 1960, when it was trurned back to local control. Some internal State Hwy Dept maps also showed Wilson Ave between M-21/Chicago Dr & M-114/28th St in Grandville as a short connector designated M-132 in the late-1930s, but the Dexter-Ann Arbor route had been M-132 for a decade by that time and it is assumed this label was in error. (M-132 was approved as a state trunkline highway route by the State Highway Dept advisory board on October 19, 1928.)
M-133 NEV 1932—1970 While no definitive source has been found to date, the erroneously marked "M-132" along Wilson Ave in downtown Grandville between M-21/Chicago Dr and M-114/28th St in the late 1930s (see M-132 above) may have been a cartographic error and the short segment of Wilson Ave may have been designated M-133, but mis-labeled. If this is the case, this short connector route is likely never signed with its own route number in the field and, if it was, it was only fofr a short time in the 1930s and was likely signed as "TO M-21" and "TO M-114" (or "TO [the other beltline routes]". The 1957 State Highway Dept Control Section Atlas, which very clearly labels every trunkline segment with its route designation, explicitly shows this segment of Wilson Ave as "part of 41041," which which was the Control Section number for M-21/Chicago Dr in Grandville from Kenowa Ave to 28th St. So, at least in the mid-1950s as far as the State Highway Dept was concerned, M-21 was a "three-legged" route at Grandville.

M-144 [I] P/NU 1929—1935 The first M-144 was never actually signed in the field. It was assigned to a proposed diagonal highway from Lake Odessa northwesterly to another proposed-but-never-built north-south trunkline highway running between Hastings and US-16 near Elmdale. At some point prior to its cancellation, Proposed M-144 was redesignated as a proposed realignment of M-50 instead, but the entire route wes cancelled in 1935 without any work ever having been done on it.
M-144 [II] FMR 1936—1940 The second M-144 debuted in 1936 and served as a short connector route from M-39/Michigan Ave (later M-43, now M-143) to the Michigan State Police Headquarters in East Lansing. Four years later in 1940, M-144 was transferred back to local control.
M-144 [III] FMR 1940—1973 The M-144 designation was almost immediately transferred onto what had been previously designated M-72 from M-76 east of Roscommon to M-72 near Luzerne. A few realignments from the late-40s to the early-60s brought M-144's termini to downtown Roscommon and M-72 near Eldorado. When the completion of I-75 in 1973 made M-18's route northwest of Roscommon unnecessary, it was transferred onto the route of M-144, completely supplanting it. The M-144 designation has not been used since.
M-145 FMR 1937—1956 The M-145 designation was to be used for a western bypass of the City of Jackson which was never completed. M-145—which would have likely been redesignated as M-50 or BYP M-50 if completed—was to begin at M-50 near Vandercook Lake and run arc westerly, northwesterly and northerly around the City of Jackson, connecting back with M-50 northwest of Jackson. One section of highway was acutally designated M-145 (on paper, if not in reality): Springport Rd between Airport Rd and Rives Junction Rd. This proposed bypass was dropped in the mid-1950s in favor of the eastern (now US-127) freeway bypass. The M-145 bypass is originally approved by the State Administrative Board at its April 11, 1930 meeting, but not officially established as a state trunkline highway route until 1937.
M-146 FMR 1933—? M-146 dates to 1933 when a north-south M-21 Connector route along 24th St in western Port Huron between US-25 (later M-25, now BL I-94) and M-21 (now Lapeer Rd). In 1954, a new approach highway was constructed leading away from the Blue Water Bridge, arcing southwesterly to M-21/Lapeer Rd and was designated M-146, connecting with the existing M-146 routing by jogging east on M-21. This new approach route was converted to freeway in c.1958. In 1964, much of the newer freeway portion of M-146 was assumed into the I-94/US-25 freeway, while the westernmost portion of that freeway section of M-146 became somewhat of a glorified off-ramp from I-94, but retaining the M-146 designation. At that time, though, the original 24th St alignment of M-146 was turned back to local control. At some point after that—possibly when the M-21 freeway spur was completed—the M-146 desingnation was dropped and has not been re-used since.

In 1934, an M-158 loop was under construction north on Pioneer Rd from Burt Rd to Montgomery Rd, then west on Montgomery back to M-9 at Frontier, effectively making it a loop from M-9. Later in 1934, it seems the routing of M-9 was transferred to the new M-158, but the M-158 routing continued to appear on official highway maps until 1936! The M-158 designation has not been re-used since.

M-9 was originally proposed to bypass Springport to the east (to eliminate two New York Central RR crossings), so M-160 was to have used Main St from Green St (proposed M-9) westerly ½ mile into downtown Springport. The M-9 bypass was never built and the temporary route through Springport became the permanent one, so M-160 was never actually signed in the field.

In this case, M-170 connected downtown McMillan in Luce Co with M-28 south of town. This 0.4-mile long route ony existed for a very short time and may never have been signed in the field, as it never appeared on any Official Highway Map issued to the motoring public (only appearing on internally-issued State Highway Dept maps.)
M-171 FMR 1932—1934
1936—1960
M-171 debuted in 1932 as a loop route off US-23, beginning in northern Alcona Co, looping northwesterly through Spruce, then north and northeast to meet back with US-23 southwest of downtown Alpena. On Dec 31, 1934, that route was turned back to local control. Then on Aug 20, 1936, M-171 was rechristened along the former inland route of US-23 from Oscoda to near Spruce in Iosco and Alcona Cos. This iteration of M-171 was removed on Sept 27, 1960 and its former route received the F-41 designation in 1970. (There may have been an even earlier iteration of M-171 along Getty Ave in Muskegon for a short time prior to the Alpena Co designation.)
M-172 FMR c1930—1937 One of many very short state highway spur routes around the state, usually connecting a downtown district with a nearby state highway bypassing the center of the city. In this case, M-172 connected downtown Middleville in Barry Co with M-37 on the east side of town. This was when M-37 entered the area via State Rd and E Main St, then turned northerly to leave town via Grand Rapids St and Whitneyville Rd. M-172 ran along Main St from Grand Rapids St westerly into the downtown district.
M-173 [I] FMR c1929—1938 One of many very short state highway spur routes around the state, usually connecting a downtown district with a nearby state highway bypassing the center of the city. In this case, M-173 connected downtown Orleans in Ionia Co with M-44 north of town in the mid-1930s. Unclear if it was ever signed in the field.
M-173 [II] FMR 1939—1972 M-173 was the last of four route designations to be applied to the route through downtown Menominee from the Ann Arbor Railroad ferry docks to US-41. This fourth designation—replacing the M-35 routing through downtown—existed from 1931 to 1972 and was likely removed after the carferry stopped running from Elberta to Menominee. Addition to trunkline system approved by State Administrative Board on June 19, 1931. Initially designated on internal State Hwy Dept maps as "US-41 STUB" and then as M-180 and then part of M-35 until the M-173 designation was transferred to it after the cancellation of the Orleans spur.
M-174 [I] FMR 1930—1938 One of many very short state highway spur routes around the state, usually connecting a downtown district with a nearby state highway bypassing the center of the city. In this case, M-174 connected downtown Buchanan in Berrien Co with M-60 at first and then later US-112 (now US-12) south of town.
M-174 [II] FMR 1939—1972 Originally designated M-120, the portion of Logan St (now M L King Jr Blvd) in Lansing from Grand River Ave to the Ingham/Clinton Co line was designated M-174 in 1939. It was turned back to local control in 1972.
M-175 FMR 1931—1938 One of many very short state highway spur routes around the state, usually connecting a downtown district with a nearby state highway bypassing the center of the city. In this case, M-175 connected downtown Galien in Berrien Co with M-60 at first and then US-112 (now US-12) south of town. Addition to trunkline system approved by State Administrative Board on June 19, 1931.
M-176 FMR 1931—1938 One of many very short state highway spur routes around the state, usually connecting a downtown district with a nearby state highway bypassing the center of the city. In this case, M-176 connected downtown Durand in Shiawassee Co with M-71 north of town.
M-177 FMR 1936—1939 M-177 replaced the M-46 designation along Michigan Ave from US-27/M-46 in downtown St Louis to US-27A (later BUS US-27, now BUS US-127) just east of downtown Alma in late 1936. M-177 lasted until late-1939.

M-180 FMR 1933—1935 M-180 was the second of four route designations to be applied to the route through downtown Menominee from the Ann Arbor Railroad ferry docks to US-41. The M-180 designation existed from 1933 to mid-1935 and was replaced by the M-35 designation.
M-181 FMR 1933—1955 M-181 began as a short spur route leading into downtown Metamora from M-24 in Lapeer Co in 1933, but was extended to M-53 north of Almont in late-1935. M-181 was turned back to local control in mid-1955 and the designation has not been used since.

M-213 [I] FMR 1935—1960 The first M-213 was a 14-mile highway running along present-day B-35 from M-46 east of Muskegon to M-20 (now M-120) at Brunswick, east of Holton established in January 1935. It was turned back to local control in January 1960.
M-213 [II] FMR c1960—1971 The second M-213 was immediately christenend along what had been M-20 from US-31 (now Whitehall Rd) in North Muskegon to Muskegon State Park. This North Muskegon-to-Muskegon State Park route survived until September 1971 when it was turned back to local control.
M-214 FMR 1935—1953 M-214 dated to early-1935 when the former M-79 route from west of Nashville to downtown Vermontville was re-designated M-214. (At this time, M-66 through Ionia Co was designated M-14.) The highway was later scaled back from Vermontville to end in downtown Nashville, serving as a 3-mile connector route along today's M-79 from M-79 west of Nashville to M-14 in Nashville. M-214 survived M-14's redesignation as M-66 in 1941 by about a decade, until it was supplanted by a rerouting of M-79 in 1953.
M-215 FMR 1935—1957 M-215 was a 7-mile route running from US-12 in Lawrence to M-43 just east of Bangor in Van Buren Co. The M-215 route markers may have been removed from the route as early as late-1953 or early-1954, but the highway itseld was turned back to local control (becoming Co Rd 215) in mid-1957.

In 1937, M-218 was extended into downtown Pontiac. On the final day of 1963, the entire route was transferred to local control. Extensions of M-218 southwesterly through South Lyon to US-12 at Chelsea and northeasterly via Utica to US-25 at Richmond were proposed in the 1930s, but never built. These extensions would have turned M-218 into a de facto Detroit bypass route.
M-219 FMR 1936—1966 M-219 was one of several highways whose sole purpose was to connect the various railroad and carferry docks with the state highway system. Others were located in Menominee, St Ignace, Elberta, Ludington, Muskegon, etc. Commissioned in 1936, M-219 lasted until 1966 as the Ann Arbor Railroad slowly decreased the number of ferry sailings from Elberta to Manistique, ending the service in 1967.

BS I-496 would have followed the Homer-Howard one-way pair northerly from I-496 to M-43/BUS M-78 on the Saginaw-Sheridan one-way pair (present-day Saginaw-Oakland Sts), then westerly to US-27/Cedar-Larch Sts, northerly to North St, westerly to W Grand River Ave, then northwesterly out of Lansing back to the proposed I-96 at present-day Exit 90. The designation was never used, to that extent, however, although it appears that BS I-496 may have been the designation assigned to the Homer–Howard one-way pair from I-496 northerly to Grand River Ave from 1962–1966 when US-127 took over.

FMR 1958—1959 Once proposed as a radial highway or freeway extending Detroit's John C Lodge Frwy northwesterly across Oakland Co to meet up with the Fenton-Clio Expwy (present-day US-23) at Fenton, potentially as the primary route from Detroit to Flint, Saginaw and on toward the Straits of Mackinac before the genesis of I-75 through Detroit's northern suburbs via Pontiac and on to Flint. Built as a divided highway as far as Orchard Lake Rd in central Oakland Co, a freeway extension was proposed for many years to meet with the proposed I-275 (and later M-275) freeway, while the remainder of the proposed highway to Fenton was cancelled. It wasn't until the 21st Century that the last plans for a Northwestern Highway Extension finally seemed to be finally killed off for good.
WIARD RD FMR 1958—1959 After the US-12 designation is removed from the Wiard Rd segment of the Willow Run Expressway system (the north-south segment between present-day US-12 and I-94 east of Ypsilanti) with the opening of the "Willow Run Bypass" (present-day I-94 between present-day US-12 and Wiard Rd) in October 1958), Wiard Rd itself remains an unsigned state trunkline for a time until it is transferred to county control June 28, 1959. During that time, Wiard Rd did not have a route designation and it is unclear if any other internal MSHD "designation" was used to refer to it other than it's acutal road name of Wiard Rd, thus it is being listed here as such for this time period prior to its cancellation as a trunkline.

TO I-75 FMR 1963—1969
1969—1971
This "TO I-75" designation existed in Metro Detroit while I-75 was being constructed through the city. In the field, this route was posted with "TO I-75" route marker assemblies as opposed to simply posting "I-75" markers alone or as a "TEMP I-75" routing.
The first "TO I-75" routing at Detroit began at the current US-24 CONNECTOR in Taylor, continuing north on US-24/Telegraph Rd to M-102/Eight Mile Rd, then east on M-102 to Stephenson Hwy, turning north on Stephenson (formerly M-150) to 11 Mile Rd, where a completed segment of I-75 picked back up.
The second routing began at the I-75 & M-39/Southfield Rd interchange at Lincoln Park, continuing north on M-39/Southfield Rd & Frwy to M-102/Eight Mile Rd, then east on M-102 to I-75. A disconnected part of "TO I-75" existed between 9 Mile and 11 Mile Rds. The M-39/M-102 portion of "TO I-75" was "decommissioned" in 1969, with the short 9 Mile-to-11 Mile Rd section remaining until 1971.
TO I-75 FMR 1962—1973 This "TO I-75" designation existed in Central Michigan while I-75 was being constructed from Bay City to Grayling. In the field, this route was posted with "TO I-75" route marker assemblies as opposed to simply posting "I-75" markers alone or as a "TEMP I-75" routing
"TO I-75" began at the jct of US-10, US-23 & M-25 west of Bay City, continued westerly along US-10 to Clare, then northerly along US-27 from Clare to the completed portion of I-75 south of Grayling. "TO I-75" lasted until I-75 was completed along its present route in 1973.
TO I-75 FMR c1961—1962 This "TO I-75" designation existed in Northern Michigan while I-75 was being constructed from Gaylord to Indian River. In the field, this route was posted with "TO I-75" route marker assemblies as opposed to simply posting "I-75" markers alone or as a "TEMP I-75" routing
According to the Official Michigan Highway Map and internal State Highway Dept Control Section Atlases, "TO I-75" began in 1961 along what had been US-27 from Gaylord to just north of Indian River near Topinabee, lasting only about a year when I-75 was completed along the stretch in the Fall of 1962.
TO I-94 FMR ?—1966 The "TO I-94" designation existed in Metro Detroit while I-94 was being constructed in southeastern Macomb Co. In the field, this route was posted with "TO I-94" route marker assemblies as opposed to simply posting "I-94" markers alone or as a "TEMP I-94" routing
"TO I-94" began at the end of I-94 at M-102/Vernier Rd in Harper Woods, continuing west on M-120 to US-25/Gratiot Ave, then north on US-25/Gratiot Ave to Metropolitan Pkwy, then easterly back to a completed segment of I-94. In 1964, "TO I-94" was moved from Metropolitan Pkwy south to 14 Mile Rd. In 1966, when I-94 was completed through southeastern Macomb Co, the "TO I-94" designation was removed.
TO I-196 FMR 1967—1974 The "TO I-196" designation existed in Allegan and Ottawa Cos while I-196 was being constructed between Holland and Grand Rapids. In the field, it is assumed this route was posted with "TO I-196" route marker assemblies as opposed to simply posting "I-196" markers alone or as a "TEMP I-196" routing. This route was shown on internal Dept of State Highways "Control Section Atlases" which tend to be quite accurate and thorough as to route designations, although "TO I-196" was never shown on the official highway map, unlike the other "TO" route designations.
"TO I-196" began at the north end of completed I-196 south of Holland and continued northerly along US-31 to the M-21 interchange east of downtown, then followed M-21 around the south side of Zeeland and then northeasterly through Hudsonville, terminating at the end of the completed freeway at the Ottawa/Kent Co line between Jenison and downtown Grandville. "TO I-196" was removed when the I-196 freeway was completed in 1974.
