  New! 2024-03 M-132 was a diagonally-trending, spur trunkline route connecting the Village of Dexter (which became a city only in 2014) with the City of Ann Arbor in Washtenaw Co for a total of 31 years. M-132 was commissioned at a time when many short spur routes—most of which were much shorter than M-132—were being established around the state to connect communities which were not right on a state trunkline route. While many of those shorter spur routes were purged from the state highway system at the end of the 1930s, M-132 lasted until January 1960 before it, too, was cancelled and turned back to county and municipal control.
  New! 2024-03 With the exception of a short 3–4 block section of Main St in downtown Dexter, the roadnames for M-132 primarily referenced the two communities the route connected. In the City of Ann Arbor, M-132 was known as Dexter Ave, while in the Village of Dexter, it was mostly known as Ann Arbor St. In between the two it was named, what else, Dexter–Ann Arbor Rd.
History: 1929 (Apr 5) New! 2024-03 – A 7.0-mile state trunkline spur route is established running from the Ann Arbor west city limit (approximately ½ mile northwest of the Dexter Ave & W Huron St–Jackson Rd intersection) then continuing west-northwesterly along Dexter-Ann Arbor Rd into Dexter, ending at the Mill Creek bridge on the Dexter west village limit.
  1931 (May 19) New! 2024-03 – Act 131 of 1931, which gives the State Highway Dept powers to establish, sign and maintain trunklines through cities, sees the official establishment of Dexter Ave from M-132's eastern terminus at US-12/W Huron St–Jackson Ave northwesterly to the Ann Arbor west city limit. At this point, M-132 in its entirety has been established as a trunkline route and is under state control.
  1935 (Jan 7) New! 2024-03 – While it's currently a spur highway route ending at Dexter, a new trunkline route is established for the proposed "Chicago–Montreal Highway," one of three major diagonal highways proposed by the State Highway Dept "to obviate the excessive travel distances imposed by a section line or rectangular system of highways." This highway through Washtenaw Co would start on US-12/Jackson Rd near Sylvan and proceed east-northeasterly past Chelsea, through the heart of Dexter and then into southeast Livingston Co east of Whitmore Lake. Within Dexter, the route established would enter the village crossing the Mill Pond to hit the cnr of Broad & Grant Sts, continue on a new alignment to Central St between Main & Fifth Sts, then run along Central St to the NYC Railroad at Second St where it would continue east-northeasterly across the Huron River and out of the village. If constructed, M-132 would then intersect this major through highway, also doubling as a bypass of Detroit and Ann Arbor for long-distance travelers.
  1957 (Jan 21) New! 2024-03 – Just two weeks beyond extactly 22 years after it was first officially established as a state trunkline route, the proposed "Chicago–Montreal Highway" (M-218) through Dexter is quietly cancelled as a trunkline route after the need for such a route is largely replaced by the system of freeways and Interstate highways now beginning to be constructed across the state.
  1959 (Aug) New! 2024-03 – All 7.7 miles of M-132 are completely repaved with asphalt in preparation for the planned cancellation of the route and jurisdictional transfer to county and municipal control.
  1960 (Jan 6) New! 2024-03 – The entirety of M-132 is cancelled as a state trunkline route and turned back to local control after 31 years of service. The M-132 route designation has not been used since on any other highway in the state.
Controlled Access: No portion of former M-132 upon decommissioning existed as freeway or expressway.
