US Highway 127 (US 127) is a part of the United States Numbered Highway System that runs from Chattanooga, Tennessee, to the Lower Peninsula of Michigan. In Michigan, it is a state trunkline highway that runs for 214.12 miles (344.59 km), entering from Ohio south of Hudson and ending at a partial interchange with Interstate 75 (I-75) south of Grayling. Prior to 2002, US 127 ended at I-69 north of Lansing–East Lansing, a total of approximately 83 miles (134 km). US 127 is the primary route connecting Lansing and Central Michigan to Northern Michigan and the Mackinac Bridge. From the south side of Jackson northerly, it is mostly a four-lane freeway. A notable exception is a 16-mile (26 km) stretch from north of St. Johns to just south of Ithaca, where the highway is built as an expressway and speed limits are lower. South of Jackson to the state line, the trunkline is a two-lane, undivided highway with access from adjacent properties.
