Lake Street (Chicago)

Lake Street is an east–west street in Chicago and its suburbs. Part of Lake Street is designated as U.S. Route 20. Lake Street begins in the city of Chicago and travels west and slightly north to the Chicago suburbs. It ends at the eastern terminus of the Elgin Bypass around Elgin, where U.S. 20 once was routed west through downtown Elgin onto Villa Street. This is a distance of about 34.4 miles (55.4 km).[1]

Route descriptionEdit

The Green Line elevated tracks run above Lake Street in Chicago. April 2002

Lake Street begins (or, rather, ends, in the case of motor traffic) at Stetson Avenue in the Illinois Center area of the Chicago Loop (middle and lower levels extend one block further east to Columbus Drive on a multi-level structure, with a pedestrian mall on the upper level) and then runs to the west as a one-way eastbound street. From the first two-way traffic segment at Canal Street, it continues to the west through the city of Chicago before heading into the western suburbs. For most of the first 7 miles (11 km) between Wabash Avenue and Laramie Avenue, Lake Street runs beneath the elevated Green Line CTA tracks and the Union Pacific (former Chicago and Northwestern) railroad tracks near Central Avenue.

Chicago Transit Authority control tower 18 guides elevated Chicago 'L' north and southbound Purple and Brown lines intersecting with east and westbound Pink and Green lines and the looping Orange line above the Wells and Lake street intersection in the loop.

In Stone Park, Lake Street runs concurrent with U.S. 20 at Mannheim Road. Eastbound U.S. 20 turns south with U.S. Routes 12 and 45. Westbound U.S. 20 follows Lake Street westbound to the western terminus of Lake Street for 20.7 miles (33.3 km).[1] A portion of Lake Street in Elmhurst has been replaced by the Eisenhower Expressway; at this point, U.S. 20 runs on the Eisenhower for 0.97 mi (1.56 km).[2] Lake Street parallels the Eisenhower until the interchange with Interstate 355.

Continuing west, Lake Street becomes a six lane divided highway while passing through the western suburbs; at Roselle, it becomes a four-lane divided highway. At the current western terminus of the Elgin-O'Hare Expressway41°58′55″N 88°08′22″W / 41.9819°N 88.13957°W / 41.9819; -88.13957, Lake Street becomes six lanes once again through Hanover Park. Just west of the Villa Olivia Country Club, Lake Street ends at the eastern terminus of the Elgin Bypass.


Most of Lake Street was once marked as U.S. 20.[3] In 1938, U.S. 20 was moved onto Mannheim Road and La Grange Road. The remaining segment of Lake Street became City U.S. 20.[4] In 1960, it was renamed to Business U.S. 20.[5] In 1968, all designations were dropped from Lake Street east of Mannheim Road.[6][7]
