Location	Chicago, Illinois–Hammond, Indiana

City U.S. Route 20 (City US 20) was created in 1938 to roughly follow the former alignment of US 20 through Chicago while the main highway was routed around the city. From US 20 at the intersection of Lake Street and Mannheim Road, the city route went east on Lake Street. At Harlem Avenue, it turned south to continue east on Washington Boulevard. At Garfield Park the route split, eastbound traffic followed Warren Boulevard while westbound traffic followed Washington Boulevard. Initially, opposing traffic traveled together on Washington Boulevard from Union Park to the South Branch Chicago River where it followed Wacker Drive to Michigan Avenue. When Chicago changed many downtown streets to one-way in 1955, eastbound traffic followed Washington Boulevard while westbound traffic followed Randolph Street. The route followed both streets to Michigan Avenue for four years before returning to Wacker Drive. At Michigan Avenue, the route joined City US 12 to head south. The original route took 16th Street one block east to Indiana Avenue and thence to Cermak Road. In 1958, eastbound traffic continued on Michigan to Cermak Road while westbound traffic followed Indiana Avenue to 14th Street. The route followed Cermak Road to a short diagonal named Silverton Way to South Parkway (now Martin Luther King Drive). From there, the route followed Oakwood, Drexel, and Hyde Park boulevards to Jackson Park. Traversing the park on what came to be known as part of Cornell Drive (Avenue), the route continued South on Stony Island Avenue, rejoining US 20 at 95th Street.^[8] In 1960, this route was redesignated as U.S. Route 20 Business (US 20 Bus.).^[9] The eastern end of the route was moved in 1963 to the Chicago Skyway as Toll Business U.S. Route 20 (Toll Bus.
