The Illinois State Highway Authority set out on a massive endeavor to reconstruct the highly traveled Jane Addams Memorial Tollway (I-90) in Cook County, IL, to increase capacity and improve the overall infrastructure.
Benesch led construction management services for the roadway and bridge reconstruction and widening for this section of I-90 from IL Route to Arlington Heights Road. The project involved the construction of nine new retaining walls, 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 included a complex maintenance of traffic plan, extensive utility coordination and conflict resolution, and 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.
