context_page_description: U.S. Route 14, an east–west route, is one of the original United States highways of 1926. It currently has a length of 1,398 miles, but it had a peak length of 1,429 miles. 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.
context_section_description: In the state of Illinois, U.S. 14 runs southeast from north of Harvard to Chicago via Woodstock and the northwest suburbs. Southeast of Route 47, U.S. 14 has four lanes; and at times it is a high-speed divided highway. Continuing southeastward from just after the overpass above Route 31, U.S. 14 passes beneath and then closely parallels the tracks of the Union Pacific Railroad's Harvard Subdivision. 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).
  At an earlier point, U.S. 14 extended south on Lake Shore Drive onto Michigan Avenue.
