M-48 Route Marker On to Next Route:
Western Terminus:    I-75 at Exit 373, 1½ miles east of Rudyard
Eastern Terminus:    M-134, 9.9 miles west of DeTour Village and 6 miles south of Goetzville
Length: Updated 43.723 miles
Maps: Route Map of M-48
Notes: Until 1949, M-49 continued westerly from Rudyard through Trout Lake and Rexton, then northwesterly to Newberry. Between 1949 and 1960, M-48 ran southerly from east of Rexton to end at US-2 in Epoufette. Then in 1960, all of M-48 west of US-2 (present-day H-63/Mackinac Trail) at Rudyard was removed from the state highway system.
  When originally constructed, I-75 did not feature an interchange at M-48. Rather, M-48 passes over I-75 and continues westerly to H-63/Mackinac Trail, then northerly via Mackinac Tr to Rudyard before turning back easterly to meet up with I-75 at Exit 373—resulting in a kind of "U-Turn" routing at its western end. Some discussion of building a full or partial interchange at the M-48 overpass over I-75 has occurred in recent years, however.
  New! In "State Trunkline Needs, 1960–1980," a set of maps prepared by the State Highway Dept's Office of Planning, Programming Division in 1960 showing possible additions, upgrades and improvements to the state trunkline system over the ensuing twenty years, MSHD staff recommended one very profound change to the route of M-48 during that timeframe. SImply put, it felt its existence as a state trunkline highway was not justified and recommended turning the entire route, as it existed in 1960, back to local control. That year, the portion west of US-2 at Rudyard wasjurisdictionally transferred to the counties in which it travelled, while the part to the east has been retained to date. This, this recommendation was only partially implemented.
History: c.1920 – The original M-48 routing begins at M-12 (later US-2) at "Caffey Corner," four miles east of Rexton (present-day intersection of Hiawatha Tr & Trout Lake Rd) and heads easterly toward Trout Lake. The first three-quarters of the distance from Caffey Corner to Trout Lake runs along a road that is today a minor two-track route through the forest—the last quarter of the distance runs along present-day H-40/Trout Lake Rd. From Trout Lake, M-48 heads easterly through Fibre to Rudyard, then southerly and easterly to meet with M-12 (later US-2, then M-121, now M-129) near Pickford. M-48 continues southerly via M-12 for 4 miles, then "stairsteps" to the southeast through Goetzville to end at Detour Village.
  1927 – M-48 is extended by 35 miles to the northwest when it continues westerly from its former western terminus via the newly-designated US-2 (formerly M-12) for 7 miles to Garnet, then northerly through Hendricks Quarry to meet M-28 eleven miles east of Newberry. M-48 then runs westerly via M-28 into Newberry, then northerly for an additional four miles to a "northwestern terminus" at Four Mile Corner (present-day cnr of M-123 & H-37/Deer Park Rd).
  1930 – A new highway alignment of M-48 opens beginning at US-2 at Caffey Corner and running northerly then easterly toward Trout Lake, replacing the present-day "two-track" route referred to in the 1920s listing above.
  1934 – A new alignment of M-28 opens south of Newberry bypassing the town, and the former route M-28/M-48 becomes, in part, M-48/M-28A through Newberry.
  1940US-2 is rerouted between the Gould City area and Epoufette to run along the Lake Michigan shoreline and the concurrent US-2/M-48 routing becomes solely M-48. (The former US-2 along Hiawatha Trail west of M-48 at Rexton is turned back to local control.) Also, M-134 is completed through to M-48 west of Detour Village.
  1949 – The route of M-48 is shortened by 26 miles on its western end when it is rerouted southerly from the Rexton area via the route of M-117 (replacing it) to end at US-2 at Epoufette. The former M-48 westerly through Rexton and Garnet, then northerly to M-28 at McLeod's Corner is turned back to county control. Old M-48 from Roberts Corner southeast of Newberry through Newberry to Four Mile Corner becomes a portion of the newly relocated M-117. With the displacement of M-117 by the rerouted M-48, M-117 was relocated to run from US-2 at Engadine to Four Mile Corner north of Newberry. Another 9 miles is shaved from M-48 in the Detour area on the route's eastern end. A newly-constucted portion of M-134 opens along the Lake Huron shore into Detour Village, and M-48 is routed southerly via the former M-134 for two miles to end at M-134 six miles south of Goetzville.
  1960 – The route of M-48 is shortened by another 42 miles when all portions west of US-2 at Rudyard are turned back to county control, with the exception of one mile of the former M-48 along Tahquamenon Trail, which becomes a portion of the new M-123.
  1962 (Fall) New! – The 18 miles of M-48 from M-129 near Pickford easterly to Goetzville in southeastern Chippewa Co is the final stretch of gravel-surfaced state trunkline highway in the entire State of Michigan to be hard-surfaced. Since July 1957, when the State Highway Dept pledged to convert the remaining unpaved trunkline mileage to hard-surfaced, over 800 miles of highway mileage have been paved.
  1963 – With the completion of the I-75/US-2 freeway in the eastern U.P. in the Fall of 1963, M-48 is extended for a change. From its 1960-63 western terminus at US-2 three miles south of Rudyard, it is routed north along Old US-2/Mackinac Tr to Rudyard, then east for two miles to end at I-75/US-2 at present-day Exit 373.
Controlled Access: No portion of M-48 is freeway or expressway.
NHS: No portion of M-48 is on the National Highway System (NHS).
