Illinois Tollway 159th Street Interchange Project
Start/Scheduled Date of Completion:
March 2018 - May 1 2019
SQN's Role on Project:
Improvements at the Tri-State Tollway (I-294) 159th Street Interchange include rebuilding the existing 159th Street bridge and reconstructing four ramps at the 159th Street Interchange: southbound I-294 to eastbound 159th Street, eastbound 159th Street to northbound I-294, northbound I-294 to westbound 159th Street and westbound 159th Street to southbound I-294. Lighting and drainage structures will also be upgraded.
The 159th Street Bridge Project will extend the life of the interchange, increase traffic capacity and provide safe and convenient travel for Tollway customers. More than 13,000 vehicles use this interchange daily, and this project has also been coordinated with other local improvements planned for 159th Street.
