United States Highway 127

US Highway 127 in Michigan has nearly tripled in length in 2002. Today the route is approximately 215 miles long, after the US-127 designation replaced all of US-27 north of DeWitt that year. In Michigan, US-127 runs from the Ohio border south of Hudson north to the junction with Interstate 75 four miles south of Grayling.

Prior to 2002, US-127 ran from Interstate 69 north of East Lansing down to the Ohio border near Hudson, a total of 83 miles.

The highway is the primary route connecting Lansing and central Michigan to Northern Michigan and the Mackinac Bridge. It serves the cities of Hudson, Jackson, East Lansing, St. Johns, Alma, Mount Pleasant, Clare, and Houghton Lake. North of Jackson, it is mostly a four-lane freeway.
