United States Numbered Highways

U.S. Route 14 (U.S. 14), an east–west route, is one of the original United States highways of 1926. It currently has a length of 1,398 miles (2,250 km), but it had a peak length of 1,429 miles (2,300 km). For much of its length, it runs roughly parallel to Interstate 90.

As of 2004, the highway's eastern terminus is in Chicago, Illinois. Its western terminus is the east entrance of Yellowstone National Park in Wyoming, with the western terminus of U.S. Route 16 and the western terminus of the eastern segment of U.S. Route 20.[2]


Route description



US 14 enters the state from the east following a section of Interstate 90 between Spearfish, South Dakota and Sundance, Wyoming, traveling across generally dry high prairie. Devils Tower National Monument is reached from US 14 via Wyoming Highway 24 north. From Sheridan to Ranchester it briefly follows I-90 north until splitting west to head through the Big Horn Mountains. Between Dayton and Burgess Junction US 14 climbs steeply over the eastern slope of the Bighorns. US 14A splits at Burgess Junction and both routes traverse the Bighorn range and Bighorn National Forest, each with a steep descent on the western slope and then continuing across the dry Bighorn Basin, rejoining at Cody. From Cody US 14 provides a scenic route into Yellowstone National Park.

South Dakota

The South Dakota section of U.S. 14, other than a concurrency with Interstate 90, is defined in the South Dakota Codified Laws.[3]

The Laura Ingalls Wilder Historic Highway incorporates U.S. 14 from South Dakota in the west to Rochester, Minnesota in the east, where the historic roadway continues on U.S. 63. The author moved to De Smet, SD from Walnut Grove, MN via the Dakota, Minnesota, and Eastern, which parallels the highway from the Black Hills to La Crosse, WI.

US 14 and US 83 are the only national routes serving Pierre, South Dakota, one of only five state capitals not on the Interstate Highway System.


U.S. 14 enters the state from South Dakota west of Lake Benton. It goes east through several small towns on a two-lane road until New Ulm, where it is briefly a divided highway. From New Ulm to Mankato, the highway lies north of the Minnesota River. Shortly before coming to the Mankato/North Mankato area, U.S. 14 becomes a freeway bypass, which becomes an expressway east of Mankato. It currently continues east through Waseca and at Owatonna, it overlaps Interstate 35. It then heads east towards Rochester, with an expressway segment beginning at Minnesota State Highway 56 and continuing east into Rochester. After Rochester, the highway parallels Interstate 90 until Winona, where U.S. 14 picks up U.S. Route 61. The two highways overlap the rest of the way in Minnesota and cross the Mississippi River at La Crescent over the La Crosse West Channel Bridge.

Currently, U.S. 14 is being expanded into an expressway from New Ulm to Owatonna. The route will be shifted 2.5 miles (4.0 km) south so it can avoid overlapping Interstate 35. The expansion is scheduled to be completed by 2012.

The Minnesota section of U.S. 14 is defined as part of Route 7 and Routes 121 and 122 in the Minnesota Statutes.[4]


U.S. 14 enters the state of Wisconsin along with U.S. Route 61 across the Mississippi River into La Crosse. The route passes through Madison, Janesville and the village square of Walworth. U.S. 14 then exits into Illinois at Big Foot Prairie.


U.S. 14 at the Illinois-Wisconsin border.

In the state of Illinois, U.S. 14 runs southeast from north of Harvard to Chicago via Woodstock and the northwest suburbs. East of the Fox River, U.S. 14 generally has four lanes; at times it is a high-speed divided highway, and parallels the Union Pacific Northwest Metra Line. Through the northwest suburbs of Chicago, this route is commonly referred to as "Northwest Highway" and is a very busy thoroughfare. East of Des Plaines, U.S. 14 becomes Dempster Street until its intersection with Waukegan Road. From here, U.S. 14 follows Waukegan Road, Caldwell Avenue, Peterson Avenue, and Ridge Avenue to its eastern end, at the corner of Broadway and U.S. 41 (Foster Avenue).[5]

At an earlier point, U.S. 14 extended south on Lake Shore Drive onto Michigan Avenue.[2]


U.S. 14 was originally the "Black and Yellow Trail", so named as it connected Minnesota with the Black Hills and Yellowstone National Park.

In Chicago's Northwest Suburbs, it is known as Northwest Highway due to its direction as well as it paralleling the old Chicago and North Western railroad (now Union Pacific.) It was originally called the Northwest Highway from Chicago to New Ulm, Minnesota, and some street signs in New Ulm, Chicago, and towns in between still show the old designation.

From Ucross west to Sheridan, Wyoming, US 14 was initially designated U.S. Route 116 in 1926. US 116 was extended west to Cody in 1933, absorbing the Deaver-Cody US 420. The next year, US 116 became an extension of US 14. Part of this extension, including all of US 420, is now US 14A.
