}} M-20 is a state trunkline highway in the US state of Michigan that runs from New Era to Midland. It crosses through rural Lower Peninsula forest land between the two ends. The highway serves the college towns of Big Rapids and Mt. Pleasant, home of the main campuses of Ferris State University and Central Michigan University, both located near the trunkline. Originally in July 1919, M-20 was routed farther north along a corridor now used by US Highway 10 (US 10). The M-20 designation was shifted south to the corridor it now follows. It previously connected to Bay City, and in 1958, a freeway was opened from Bay City to Midland. The former M-20 along Midland Road, going through Auburn, was returned to local control at that time. In 1960, the M-20 freeway became US 10, moving M-20's terminus to Midland. Prior to 1969, M-20 extended on the west end to Muskegon before it was rerouted from White Cloud to New Era. ==Route description== M-20 starts near Lake Michigan at the US 31 freeway in New Era where it runs east through the Manistee National Forest, crossing the North Branch of the White River near Ferry and the South Branch near Hesperia on the way to White Cloud. There it turns south along M-37 and then east along a new routing following Baseline and Newcosta roads north of the Hardy Dam to meet the US 131 freeway at exit 131 near Stanwood. M-20 turns north, running concurrently along the US 131 freeway to Big Rapids and joins Business US 131 (Bus. US 131) at exit 139.〔〔 The section along the freeway is listed on the National Highway System (NHS), a system of highways important to the nation's economy, defense and mobility.〔 Together Bus. US 131/M-20 runs along the Perry Street commercial corridor to State Street near the main campus of Ferris State University. The business loop turns north by the campus and at Michigan Street, M-20 turns eastward to cross the Muskegon River in downtown Big Rapids, north of the campus. M-20 zig-zags southeast of town bypassing the Canadian Lakes area and turns due east through rural Remus in Isabella County and the Isabella Indian Reservation.〔〔 In Mt. Pleasant, M-20 runs near the campus of Central Michigan University crossing the Chippewa River, and the trunkline joins Bus. US 127 along the Mission Street business area to Pickard Road. The highway turns east on Pickard and passes under the US 127 freeway near the Soaring Eagle Casino. From Mt. Pleasant to Midland, M-20 is designed as a four–lane highway with a continuous center turn lane passing through rural forest land.〔〔 M-20 picks up inclusion on the NHS from this point east. Once M-20 reaches Midland on Jerome Street, it crosses the Tittabawassee River north of the Tridge, a three-legged bridge over the confluence of the Tittabawassee and Chippewa rivers. There it joins Business US 10 (Bus. US 10) on a pair of one-way streets: Indian Street (westbound) and Buttles Street (eastbound). The two streets pass by Dow Diamond, home to the Great Lakes Loons, the city's minor league baseball team. Bus. US 10/M-20 then passes some Dow Chemical Company buildings and curves into a freeway stub connecting with the US 10 freeway on the east side of town. This short section of business loop freeway has two interchanges before terminating at one final interchange. At this junction, both Bus. US 10 and M-20 have a common eastern terminus. Traffic headed eastbound on the business loop defaults onto eastbound US 10, and traffic destined for the business loop is fed from the westbound direction of the freeway only.〔 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-20 (Michigan highway)」の詳細全文を読む スポンサード リンク
