}} M-28 is an east–west state trunkline highway that almost completely traverses the Upper Peninsula in the U.S. state of Michigan, from Wakefield to near Sault Ste. Marie in Bruce Township. Along with US Highway 2 (US 2), M-28 forms a pair of primary highways linking the Upper Peninsula from end to end, providing a major access route for traffic from Michigan and Canada along the southern shore of Lake Superior. M-28 is the longest state trunkline in Michigan numbered with the "M-" prefix at . The entire highway is listed on the National Highway System, while three sections of M-28 are part of the Lake Superior Circle Tour. M-28 also carries two memorial highway designations along its route. Throughout its course across the Upper Peninsula, M-28 passes through forested woodlands, bog swamps, urbanized areas, and along the Lake Superior shoreline. Sections of roadway cross the Ottawa National Forest and both units of the Hiawatha National Forest. Some of the other landmarks accessible from M-28 include the Seney Stretch, Seney National Wildlife Refuge and several historic bridges. M-28 is an original trunkline designation, dating to the 1919 formation of the state's trunkline system. The original highway was much shorter than the current version. M-28 was expanded eastward to the Sault Ste. Marie area in the late 1920s. The western end has been expanded twice to different locations on the Wisconsin state line. Other changes along the routing have led to the creation of three different business loops at various times, with one still extant. Future changes, proposed by Marquette County but not accepted by the Michigan Department of Transportation (MDOT), could see M-28 rerouted over County Road 480 (CR 480). == Route description == M-28 is a major highway for Michigan and Canadian traffic along the south shore of Lake Superior. It forms the northern half of a pair of primary trunklines linking the Upper Peninsula from end to end; US 2 is the southern partner.〔 The highway comprises mostly two lanes, undivided except for sections that are concurrent with US 41 near Marquette. The "Marquette Bypass" portion of US 41/M-28 is a four-lane expressway, and segments of the highway in Marquette County have four lanes. The entire route is part of the National Highway System, and three sections of the trunkline are part of the Lake Superior Circle Tour.〔 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「M-28 (Michigan highway)」の詳細全文を読む スポンサード リンク
