In Michigan, it is a state trunkline highway that runs for , 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 . 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 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. The highway was first designated on November 11, 1926, along a series of existing state highways from Lansing southward toward Toledo. In 1930, the southern end was rerouted south of Somerset in rural northwestern Lenawee County to a course that ran directly south to the Ohio state line; the remainder was renumbered US 223. Starting in the 1950s, the highway was reconfigured to bypass Mason and other communities, converting US 127 into a freeway from Jackson to the Lansing area by the mid-1970s. When the Michigan Department of Transportation (MDOT) successfully petitioned the American Association of State Highway and Transportation Officials (AASHTO) in 1999 to remove US 27 from the state, US 127 was to be extended northward from Lansing to Grayling as the replacement designation. This change was made in 2002, resulting in the current configuration of the highway in Michigan. The United States Congress has designated an additional Interstate Highway, to be part of I-73 that would replace most or all of US 127 through Central and Southern Michigan, but any plans by MDOT to complete this highway were cancelled in 2001. ==Route description== Running just about in Michigan, US 127 runs north–south up the center of the Lower Peninsula. North of its junction with US 223 in Lenawee County, it is listed as a part of the National Highway System, a system of roads importance to the nation's economy, defense and mobility. As a state trunkline highway, the roadway is maintained by the Michigan Department of Transportation (MDOT), and it includes approximately of freeway in two segments, the southernmost running between Jackson and Clinton counties, separated by an gap from the northernmost segment between Gratiot and Crawford counties.〔 According to the department, 1,253 vehicles use US 127 on average near the state line, and 68,853 vehicles do so between M-43 and Kalamazoo Street in Lansing, the lowest and highest traffic counts along the highway in 2013, respectively. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「U.S. Route 127 in Michigan」の詳細全文を読む スポンサード リンク
