Highway system

U.S. Route 12 (US 12) is an east–west United States highway, running from Aberdeen, Washington, to Detroit, Michigan, for almost 2,500 miles (4,000 km). The highway has mostly been superseded by Interstate 90 (I-90) and I-94, but unlike most U.S. routes that have been superseded by an Interstate, US 12 remains as an important link for local and regional destinations.

The highway's western terminus is in Aberdeen, Washington, at an intersection with US 101, while the highway's eastern terminus is in Downtown Detroit, at the corner of Michigan and Cass avenues, near Campus Martius Park.

Route description

Washington

Western terminus at US 101 in Aberdeen, WA

The western terminus of US 12 is located in Aberdeen, Washington. In the 1960s, a portion of US 12 was moved north to the town of Morton, when the Mossyrock Dam was built and flooded the towns of Kosmos and Riffe, along the Cowlitz River in Lewis County. A large portion of old, two-lane US 12 was replaced by Interstate 82 and Interstate 182 in the 1980s, between Yakima and the Tri-Cities, though the freeways are still cosigned with the US 12 designation. The old two-lane highway now bears the name Wine Country Road. The highway loosely follows the eastbound leg of the Lewis and Clark Expedition, between Wallula, Washington and Clarkston, Washington, thus being marked as part of the Lewis and Clark Trail. The east end of the highway in the state is at Clarkston, where the highway crosses the Snake River into Idaho at Lewiston.

The Washington section of US 12, other than a concurrency with Interstate 5, is defined at Washington Revised Code § 47.17.055.[1]

Idaho

US 12 enters the state at Lewiston, crossing the Snake River from Clarkston, Washington. It ascends the Clearwater River, concurrent with US 95 for seven miles (11 km). It reduces to a two-lane undivided highway with signs that read "winding road next 99 miles" and goes on to Orofino, continuing up the middle fork of that river to Lowell, the junction of the Lochsa and Selway Rivers. It continues up the Lochsa and climbs to Lolo Pass at the Montana border. This portion of the highway is also designated as part of the Lewis and Clark Trail. Most of the highway in Idaho is within the Clearwater National Forest. The eastern section of US 12, through remote mountain forest and up to Lolo Pass, was built in the early 1960s, making it the last US highway constructed. No services are available between Lowell and Powell, about seventy miles (110 km) further east.

US 12 through Idaho has been proposed for surface shipment of huge equipment from Lewiston, an inland port,[2] to oil sands facilities in Alberta near Fort McMurray, and to a refinery in Billings, Montana. On two-lane portions of the road, the equipment, weighing as much as 300 tons and as much as 30 feet (9.1 m) high and 24 feet (7.3 m) wide, would occupy the entire roadway. The route is preferable to others due to the lack of underpasses and the great distances involved. The alternative is transport across the Great Plains from Texas or New Orleans.[a] The major obstacles on US 12 are power lines, which would have to be raised or buried. That and other alterations to the highway, such as turnouts, would be paid for by the companies. The trucks would transport only at night, moving short distances between places where they would pull off and let traffic pass. A permit granted by the Idaho Transportation Department to ConocoPhillips in August 2010 is the subject of litigation initiated by householders along the route.[3] On January 19, 2011, it was announced that the Idaho government would issue permits for four loads of refinery equipment to be transported from Lewiston to Billings.[4]

Montana

US 12 in Montana has been defined as the Lewis and Clark Highway,[5] despite not being the route followed by Lewis and Clark across the state.[6]

US 12's 592 miles (953 km) through Montana's mountains and plains is the greatest distance that US 12 traverses through any state. The highway enters Montana at Lolo Pass, seven miles (11 km) southwest of Lolo Hot Springs in the Lolo National Forest. After passing Lolo Peak to the south and traveling east for 33 miles (53 km), it meets with US 93 at Lolo and continues as a concurrency northeast for 7.5 miles (12.1 km), where US 93 heads due north on Reserve Street, toward Glacier National Park. US 12 continues northeast through Missoula's downtown, eventually meeting I-90. It then overlaps I-90 for 69 miles (111 km), until Garrison, where it heads east toward Helena for 48.8 miles (78.5 km). This two-lane section of the trip passes through Avon and Elliston winding through the Helena National Forest, over the Continental Divide at MacDonald Pass, and then through Montana's capital city, Helena. US 12 passes over Interstate 15 at which, point it joins US 287 south. US 12 overlaps US 287 and heads southeast, toward Townsend for 33.4 miles (53.8 km), where it splits from US 287, which heads south for 30 miles (48 km) toward the intersection of I-90 near the town of Three Forks. US 12 heads east toward White Sulphur Springs for 42.2 miles (67.9 km). The route joins US 89 for 8.4 miles (13.5 km) before entering White Sulphur Springs, and for another 3.0 miles (4.8 km) east of town. US 89 splits north and US 12 continues east on its own for 233 miles (375 km), until the junction with I-94 at Forsyth as a concurrency northeast for 45.8 miles (73.7 km), to Miles City. At the east exit for Miles City, US 12 splits again from I-94 and heads almost directly east to the North Dakota border at a distance of 92.4 miles (148.7 km).

North Dakota

US 12 is a two-lane undivided highway that runs 87.47 miles (140.77 km), through Adams, Bowman and Slope counties in southwest North Dakota. The speed limit is 65 miles per hour (105 km/h) on rural segments, with slower posted speeds within the cities of Marmarth, Rhame, Bowman, Scranton and Hettinger. US 12 meets with US 85 in Bowman, and the routes are concurrent for a short distance through the city.

South Dakota

US 12 enters South Dakota from North Dakota as a rural two lane highway about 10 miles (16 km) west/northwest of Lemmon before entering the Standing Rock Reservation. For approximately the next 70 miles (110 km), US 12 runs parallel to the border of North Dakota, sometimes within less than a mile. At Walker, US 12 heads southeast for 37 miles (60 km), where it crosses the Missouri River at Mobridge, exiting the reservation. From there it continues east for 18 miles (29 km), until it meets with US 83 near Selby. It overlaps US 83 for 7 miles (11 km). After leaving US 83, it turns due east and spends about 80 miles (130 km) as a rural two lane highway again. A few miles before reaching Aberdeen, it becomes an at-grade expressway. After the junction with U.S. Route 281, it goes back to being two lane for a few miles through Aberdeen and past the Aberdeen Regional Airport, before once again becoming a 4-lane expressway, until 2 miles (3.2 km) before Waubay. East of Waubay it becomes again an at-grade expressway until it meets with Interstate 29 near Summit. The speed limit from Aberdeen to I-29 is 70 mph (115 km/h) except through the communities of Groton, Webster and Waubay. From there it heads southeast 22 miles (35 km), until Milbank. At Milbank, it continues east for 12 miles, until it crosses into Minnesota at Big Stone City, just south of Big Stone Lake. The South Dakota section of US 12 is legally defined at South Dakota Codified Laws § 31 April 132.[7]

Minnesota

From the South Dakota/Minnesota state line at Ortonville, to Wayzata, US 12 is mostly a rural two-lane highway with a 60 mph (95 km/h) speed limit, with slower speed limits through towns and a four-lane surface arterial segment through the city of Willmar. From western Wayzata to Interstate 394 in Minnetonka, US 12 is a six-lane freeway. East of I-494, US 12 is invisibly concurrent with Interstates 394 and 94 through Minneapolis and St. Paul to the Minnesota/Wisconsin state line at Hudson.

The Minnesota section of US 12 is defined as Routes 149, 26, and 10 in Minnesota Statutes §§ 161.115(80) and 161.114(2).[8][9]

Wisconsin

US 12 crosses the St. Croix River from Lakeland, Minnesota, into Hudson, running concurrently with I-94 before splitting just east of the city. It mainly follows a similar path to I-94 to the north, before crossing under I-94 into downtown Menomonie before continuing in an easterly direction to Eau Claire. In Fall Creek, US 12 turns southeasterly towards Fairchild, it then runs concurrently with US 10 going east for just 2.5 miles (4.0 km) before returning to its course southeast bound. US 12 eventually recrosses I-94 into Black River Falls then parallels I-94 in a southeastward direction. US 12 also runs through Millston and Kirby. Afterwards it turns directly south to Tomah, where it becomes North Superior Avenue. It alternates between a four-lane and two-lane road on its way through downtown. It then turns east for 4.5 miles (7.2 km), then parallels I-90/I-94 through Camp Douglas, New Lisbon, Mauston, and Lyndon Station before crossing under the pair of Interstates into downtown Wisconsin Dells. US 12 turns south to Baraboo and runs along the western edge of Devils Lake State Park. In Sauk City, US 12 turns southeast towards Madison and runs along the city's western and southern edges. Here it becomes a four- to six-lane freeway with US 14 and US 18 known by the locals as "The Beltline". On the southeast side of the city it crosses I-39/I-90 towards Cambridge. It turns southeast here at runs through Fort Atkinson and Whitewater. In Elkhorn, US 12 becomes a four-lane freeway with a 70-mile-per-hour (110 km/h) speed limit. It returns to a two-lane road at the Wisconsin–Illinois state at Genoa City.

Illinois

In Illinois, US 12 is an arterial surface road that runs from Richmond, southeast to Des Plaines. It then turns due south, continuing through the Chicago metropolitan area, joining with U.S. Route 45. In Stone Park, U.S. Route 20 joins U.S. 12/45. In Hickory Hills, U.S. 45 continues south, while U.S. 12/20 runs due east along 95th Street in the southwest suburbs. From Hickory Hills, U.S. 12/20 runs east nearly to the Lake Michigan lakefront and then joins with U.S. Route 41, as all three routes travel southeast into the state of Indiana.

US 12 is referred to as Rand Road in Chicago's northwest suburbs. Rand is an original name for the area around Des Plaines, Illinois, the location where the road resumes its westerly direction. South of Des Plaines, US 12 follows Mannheim Road, La Grange Road, and then 95th Street, before merging with US 41 on Ewing and Indianapolis Avenues toward the Indiana state line.

Indiana

In Indiana, US 12 is a historically significant route, that winds along the southern coast of Lake Michigan. It runs from an interchange with the Indiana Toll Road, concurrent with U.S. Routes 20 and 41 in Whiting, to Michiana Shores, at the Michigan state line. A large portion of this segment is known as the Dunes Highway.

Michigan

US 12 is now the only U.S. Highway still serving downtown Detroit, whose street grid was laid by Augustus B. Woodward, to have a five-way intersection of the roads that would become US 12, US 10, US 16, US 112 and US 25. US 24 still travels through Detroit from Puritan to 8 Mile Road on the far west side.

As from the earliest days of its existence, US 12 enters Michigan from Indiana, southwest of New Buffalo and continues to the old junction of US 12 and US 112 in New Buffalo. It is now assigned between New Buffalo and Detroit (except through Ypsilanti), along what was US 112 until 1962.

On May 4, 2004, the Michigan Department of Transportation (MDOT) designated 209 miles (336 km) of US 12 from New Buffalo to Detroit as a Historic Heritage Route. The east-west corridor traverses the counties of Berrien, Cass, St. Joseph, Branch, Hillsdale, Lenawee, Washtenaw and Wayne.

History

Since the highway's creation in 1926, the eastern terminus has always remained within a few blocks of this point.[10][self-published source?]

The western terminus was gradually extended westward, until it reached the Pacific Ocean.[11]

Former ferry crossing

In 1925, US 12 in Michigan was originally proposed to run from Detroit to Ludington, across Lake Michigan, via the Pere Marquette Railway car ferry to Manitowoc, Wisconsin, and then continuing into Wisconsin, on what later became US 10, in those two states. The 1974 "Golden Anniversary Celebration" reprint of the 1926 Rand McNally Road Atlas shows US 12 following what later became the route of US 10 through Michigan, from Detroit, through Flint, Saginaw, Midland, and Clare on its way to Ludington.

Wyoming

US 12 originally went into Wyoming, before being rerouted into Montana and was proposed to go into Oregon, but did not.
