I-90 Reconstruction, IL 53 to Arlington Heights Road

Cook County, IL

The Illinois State Toll Highway Authority set out on a massive endeavor to reconstruct the highly traveled Jane Addams Memorial Tollway (I-90) in Cook County, IL. Benesch led construction management services for the roadway and bridge reconstruction and widening for the section of I-90 from IL Route 53 to Arlington Heights Road. The project involved the construction of nine new retaining walls, the reconstruction and widening of three bridges and 2.5 miles of mainline pavement, as well as the reconstruction of ten ramps at two major interchanges. Challenges on this high-profile project involved complex maintenance of traffic; extensive utility coordination and conflict resolution; as well as outside agency coordination. Benesch performed on-site observation and documentation of the contractor’s activities as well as testing and inspection for any material placed on the site that was incorporated into the proposed work – all while ensuring project activities adhered to the aggressive construction schedule.
