M-58 is a 5.14 mile east-west state highway in the U.S. state of Michigan that runs from M-47 in Saginaw Charter Township east to Exit 3 of I-675 near the north part of downtown Saginaw.
This route is the third iteration of "M-58" in Michigan. This route came into being when the western segment of M-81 was redesignated in 1971 following the completion of I-675 into downtown Saginaw.
In the 1920s, the first M-58 was a 24-mile route connecting M-40 (now M-51) in downtown Niles with M-11 (later US 12, and presently I-94 Business Loop) south of downtown St. Joseph. In 1922, the route was extended south of Niles to the Indiana border and in 1926 the entire length was redesignated as a part of US 31.
From 1930 through 1961, a second iteration of M-58 existed in Oakland County as a western bypass around Pontiac. The route ran from US 10 (the corner of Woodward Avenue & Square Lake Road south of Pontiac west to Telegraph Road and then north along Telegraph road to US 10/Dixie Highway north of Pontiac.
