Road Work Update: Illinois 31 over U.S. 20 bridge work began April 1

The Illinois Department of Transportation announced last week that a project to replace the bridge carrying Illinois 31 (State Street) over U.S. 20 in Elgin would begin, weather permitting, Monday, April 1. To complete the work, Illinois 31 will be reduced from two to one lane in both directions, between Dana Drive and Oak Street. U.S. 20 will also be reduced to one lane in each direction, between Grace Street and McLean Boulevard. Additionally, motorists should also expect various lane shifts on Illinois 31 and on U.S. 20 approaching the bridge, along with various overnight lane closures on U.S. 20 at the bridge during that time.

Access to local residences and businesses will be maintained throughout construction.

The $19 million project consists of replacing the existing bridge with a new wider structure, widening the existing interchange ramps, installing new LED lighting and modernize traffic signals and constructing new sidewalks with ADA-compliant ramps and curbs.

The project is anticipated to be completed in summer 2026.
