Michigan
Main article: U.S. Route 12 in MichiganUS 12 is now the only U.S. highway route still serving downtown Detroit, whose street grid was laid by Augustus B. Woodward, to have a five-way intersection of the roads that would become US 12, US 10, US 16, US 112 and US 25. US 24 still travels through Detroit from Puritan to 8 Mile Road on the far-west-side.
As from the earliest days of its existence, US 12 enters Michigan from Indiana, southwest of New Buffalo and continues to the old junction of US 12 and US 112 in New Buffalo. It is now assigned between New Buffalo and Detroit (except through Ypsilanti), along what was US 112 until 1962.
On May 4, 2004, the Michigan Department of Transportation (MDOT) designated 209 miles (336 km) of US-12 from New Buffalo to Detroit as a Historic Heritage Route. The east-west corridor traverses the counties of Berrien, Cass, St. Joseph, Branch, Hillsdale, Lenawee, Washtenaw and Wayne. MDOT's Heritage Route Committee has approved the route's nomination as a premier addition to the Michigan Heritage Route Program.
US-12 is among the oldest road corridors east of the Mississippi River and accesses some of the most extensive and significant historic, cultural, scenic and recreational resources in Michigan. It begins in downtown Detroit, just blocks from the Detroit River, and extends through southern Michigan to the Michigan/Indiana border south of New Buffalo. It was originally a network of centuries-old trails created by Native Americans. Over the years it has had many names such as Sauk Trail, Chicago Road, and Michigan Avenue. —Pete Hanses, MDOT's Heritage Route managerThe U.S. 12 Heritage Trail also opens their doors annually the second weekend of August for what has been dubbed "Michigan's Longest Yard Sale" on Friday, Saturday and Sunday.
