Трасса 10 США: История и современное состояние

Highway in the United States

U. S. Route 10 or U. S. Highway 10 (US 10) is an east–west United States Numbered Highway located in the Midwest and Great Lakes regions of the U. S. Unlike most U. S. Highways with "0" as the last digit of its route number, US 10 is not a cross country highway. US 10 was one of the original long haul highways, running from Detroit, Michigan, to Seattle, Washington, but then lost much of its length when new Interstate Highways were built on top of its right of way. US 10 used to be broken into two segments by Lake Michigan. In 2015, the ferry SS Badger between Ludington, Michigan, and Manitowoc, Wisconsin, was officially designated as part of the highway. The ferry operates only between May and October. The eastern terminus of US 10 is in Bay City, Michigan, at its interchange with Interstate 75 (I 75) (near US 10's milepost 139 and I 75's milepost 162). The western terminus of US 10 is in the city of West Fargo, North Dakota, at its interchange with I 94.

Originally, US 10 also passed through Montana (including a segment of what is now Montana Highway 2 [MT 2]), the Idaho Panhandle, and Washington, terminating in Seattle. The completion of I 90 and I 94 replaced US 10 along this route, although some sections of the old US 10 road still exist in such cities as Bismarck, Missoula, Spokane, and between Cle Elum and Ellensburg as State Route 10 (SR 10). The last section of I 90 to be completed was between Coeur d'Alene and Wallace in the early 1990s. Much of this route was conumbered as both I 90 and US 10 until the final completion of I 90 through Idaho. Some decommissioned sections of US 10 are designated I 90 Business (I 90 Bus.) or I 94 Bus. routes. At least two US 10 Alternate (US 10 Alt.) routes were used, including one from Spokane to Missoula from 1941 to 1967 via Sandpoint, Idaho (represented today by US 2, State Highway 200, MT 200 and US 93), and the Pintler Scenic Route through Philipsburg, and Anaconda, renamed MT 1 when US 10 split between Garrison and Three Forks into US 10N and US 10S from 1936 until 1960. US 10N through Helena and dropping into Three Forks, while the Southern section of the split followed US 10's traditional routing through Deer Lodge and Butte, Montana, to get across the Rocky Mountains. Previous to the split, US 10N was designated as another US 10 Alt. At the eastern end, US 10 originally went south from Midland to Saginaw, Michigan, on what is now highway M 47. It then joined up with US 23 in Saginaw and continued south until it split from US 23 near Flint. It then continued southeast as the Dixie Highway to Pontiac, where it followed Woodward Avenue, now designated M 1. From there, US 10 continued on an almost straight line to Downtown Detroit, where it intersected US 16, US 25, and US 12. It then took a two block jog and then ended at the Detroit–Windsor tunnel to Canada.

US 10 has had alternate routes designated in the past, but none are active as of 2017. A multistate alternate route between Washington and Montana was largely replaced in 1947 by the western extension of US 2 and later decommissioned entirely in 1967. Between 1926 and 1934, there was a pair of suffixed routes between St. Cloud, Minnesota, and Moorhead, Minnesota. US 10N, the northern half of the pairing, connected St. Cloud, Little Falls, Motley, and Detroit Lakes before reaching Moorhead. US 10S ran from St. Cloud through Alexandria and Fergus Falls before rejoining US 10N at Moorhead. In the mid 1930s, US 52 was extended into Minnesota, and US 10S was renamed to US 52 (now I 94). US 10N was renamed to US 10.
