[edit] Route description
U.S. Route 20 in Illinois can be broken down into the following sections:
[edit] East Dubuque to Rockford
West of Elgin, U.S. Route 20 is known in Illinois as the General Grant Highway, named after the American Civil War era general Ulysses S. Grant. The Ulysses S. Grant Home, a national landmark, fronts near the highway at the eastern edge of Galena, Illinois. Signage of U.S. 20 as such is sporadic; in Marengo, the road is named the General Grant Highway, while in other portions of the state the name appears to be honorary. Approaching Freeport, U.S. 20 is routed onto a two-lane bypass around the city. The Rockford bypass routes U.S. 20 onto a full limited-access freeway; it remains this way until it multiplexes with Interstate 39 southeast of downtown Rockford.
[edit] Rockford to Elgin
East of Rockford, the routing of U.S. 20 has largely been replaced with Interstate 90, with U.S. 20 serving minor cities that are not accessible from the Northwest Tollway. It is a four-lane divided highway from I-39 to just east of Belvidere; for the rest of this segment, it is a winding, hilly, and rural two-lane road.
U.S. 20 travels through the downtowns of the small towns and unincorporated areas of Garden Prairie, Marengo, Harmony and Starks. At Starks, eastbound U.S. 20 multiplexes with southbound Illinois Route 47 and westbound Illinois Route 72, forming a wrong-way concurrency. All three routes pass beneath a railroad viaduct before separating south of Starks.
Continuing east, U.S. 20 travels through Pingree Grove before entering the Elgin area. Before entering Elgin, U.S. 20 widens to a four lane limited-access freeway that bypasses Elgin. This road is known as the Elgin Bypass.
[edit] Elgin to Indiana
At the end of the Elgin bypass, U.S. 20 takes on the name of Lake Street. U.S. 20 has numerous high-volume intersections, including a grade-separated interchange with Illinois Route 59. In Hanover Park, an early-2000s reconstruction project widened lanes on the road and created a median for safer travel; east of Barrington Road / County Farm Road, the road briefly becomes six lanes for one mile until the Elgin-O'Hare Expressway.
U.S. 20 continues in an east-southeast direction through the town center of Bloomingdale and becomes six lanes at the Bloomingdale-Roselle border. It maintains six lanes through a very high traffic corridor to Interstate 290 and onwards to Illinois Route 53 before it returns to four lanes while serving downtown Addison, paralleling Interstate 290 to the north. Past Elmhurst, the road is multiplexed with Interstate 290 for a mile, technically giving U.S. 20 ten lanes of traffic, although the rightmost two are exit-only lanes. At the interchange, westbound U.S. 20 has only one lane, but eastbound U.S. 20 has two.
U.S. 20 continues through Stone Park and Melrose Park before turning south and becoming the multiplexed U.S. Routes 12/20/45. At this point, U.S. 20 becomes Mannheim Road, and later, La Grange Road, until it turns onto 95th Street eastbound with U.S. 12. This combination later joins with U.S. Route 41, where the three routes follow Ewing Avenue and Indianapolis Boulevard out of the state.
[edit] Business Routes
U.S. 20 has been rerouted around the cities of Freeport, Rockford, Elgin and Chicago. The bypass around Freeport is currently only two lanes wide; future construction will widen this segment to four lanes. A bypass is currently planned for Galena; see Future.
The longest Business U.S. Route 20 in Illinois runs 21 miles from just west of Rockford to just east of Belvidere. The route begins just west of Weldon Road and runs as State Street into downtown Rockford, where it is split into two one-way streets (Chestnut Street and Walnut Street for eastbound traffic, Jefferson Street for westbound traffic). The route continues east along State Street all the way through Rockford and becomes a two-lane highway between Rockford and Belvidere. Business 20 is then routed in an outer loop around the city of Belvidere before merging back with US 20 near Genoa Road and Interstate 90 (Northwest Tollway).
Business U.S. Route 20 in Elgin was removed in 1984. This ran along Larkin Avenue, Highland Avenue, Chicago Street and Villa Avenue. The current routing of U.S. 20 south of Elgin is called the Elgin Bypass.
Business U.S. Route 20 in Chicago was removed in 1968. This existed from 1960 through 1968; before then, it was City U.S. Route 20 from 1938 to 1960.[2]
[edit] History
The routing of U.S. 20 has not changed since 1938. Prior to 1938, U.S. 20 continued east on Lake Street east of Mannheim Road (U.S. Routes 12/45). It ran through downtown Chicago and exited Chicago south on what is now Torrence Avenue.[2]
[edit] Future
The Illinois Department of Transportation is in the middle of a multiyear project for construction of a bypass for the cities of Galena and Freeport.[3] Long-range plans call for a full four-lane highway from Galena to Freeport. Although the bypass has been discussed for decades, the project only began to receive funding in the early 2000s.[4] As the only major corridor between Interstate 88 and Interstate 90, the Freeport to Galena project is part of a larger project to improve the viability of U.S. Route 20 between Waterloo, Iowa and Rockford.
