High Quality Content by WIKIPEDIA articles! M-58 is a 5.108-mile (8.221 km) east–west state trunkline highway in the US state of Michigan that runs from M-47 in Saginaw Township east to exit 3 of I-675 near the north part of downtown Saginaw. The trunkline follows State Street through the Saginaw area, and east of Lathrop Avenue, M-58 is split along two streets, using Davenport Avenue as well. This is the third time that the number has been used on a highway in Michigan; the first two were used in the Berrien County and Pontiac areas. The Saginaw version was designated in 1971, and it is listed on the National Highway System.
