Jane Byrne Interchange Reconstruction


Illinois Department of Transportation


Chicago, Illinois
According to the Federal Highway Administration, the Jane Byrne Interchange is the slowest and most congested highway freight bottleneck in the nation with more than 400,000 vehicles traveling through the Interchange on a daily basis, and more than 1,100 crashes reported on average per year.

Project Scope

Built more than 50 years ago, the interchange has not undergone major rehabilitation since its initial construction and has reached the end of its engineering life. High traffic volumes, single lane ramps and tight curves make the interchange prone to congestion which causes it to operate under bumper-to-bumper rush hour conditions for most of the day.

The $700 million Jane Byrne Interchange Reconstruction Project is expected to reduce traffic delays by 50%, save drivers five million hours annually, save 1.6 million gallons of fuel per year, and reduce greenhouse gas emissions by one third.  This project will benefit the community as well by creating a more pedestrian and bicyclefriendly city with the addition of bicycle lanes on Des Plaines Avenue according to the City’s master bikeway plan and wider sidewalks. The proposed work will improve the interchange’s overall safety, capacity, and geometric deficiencies through removal and reconstruction/reconfiguration of all interchange ramps to provide additional lanes, wider shoulders, and larger curves. 


The project presents many exciting and unique engineering challenges including maintaining traffic on three different interstates and working in a constricted downtown area around public transit, multiple bridges, and a City of Chicago pump station.
