each day. No segment of the highway is listed on the National Highway System, a network of roads important to the country's economy, defense, and mobility. History Previous designation M-45 was originally designated in the UP on what is now M-95 by July 1, 1919. The highway ran between M-12 in Sagola and M-15 in Humboldt Township. When the United States Numbered Highway System was created on November 11, 1926, US 2 replaced most of M-12 through the UP. M-45 was extended south of Sagola to the north side of Iron Mountain. Along with this change, M-69 replaced another previous section of M-12 and all of M-90. M-69 ran concurrently with M-45 between Sagola and Randville to connect these two highway segments. By 1933, M-45 was extended concurrently along US 2/US 141 into Iron Mountain and then as an independent routing through Kingsford to the Wisconsin state line. Before the next year, the M-95 replaced M-45 in the UP. Current designation The current designation of M-45 dates back to 1964. M-50 was truncated to end near Lowell at I-96. The remainder of M-50 on Cascade Road, Fulton Street and Lake Michigan Drive was redesignated as M-45. The eastern section from Business US 131 (Division Avenue) to I-96 was turned over to local control in 1972, shortening the route. The east end would be shortened again by 1995, removing the M-45 designation east of I-196. Jurisdiction was only transferred to the City of Grand Rapids on the portion from Division Avenue west to the Grand River, leaving part of West Fulton Street under state maintenance as an unsigned trunkline. M-45 was upgraded to a four-lane divided highway in 2001–02 between Walker and the Grand Valley State campus in Allendale. The new alignment bypassed a section of road between 24th and 40th avenues. That section was renamed River Hill Drive, but retained as an unsigned state trunkline (Old M-45).
