Client: Illinois Tollway

Location: IL Rt 47 to Elgin Plaza


In 2011, the Illinois Tollway Board of Directors approved the 15-year, $12 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. Move Illinois committed $2.2 billion to rebuilding and widening of the Jane Addams Memorial Tollway (I-90).

The improvements on this contract have improved safety with wider shoulder lanes and auxiliary lanes, reduced congestion, and thus improved travel times from Rockford to Elgin.

This Corridor Construction Manager role included the oversight of numerous contracts to reconstruct a 38-mile section of Interstate 90, the Jane Adams Tollway, from the western suburbs to Rockford, Illinois. The contract also covered construction management services for seven miles of roadway within that corridor.

The Irene Road Interchange Project built a new, full-access interchange connecting Irene Road and the Jane Addams Memorial Tollway (I-90) in Belvidere as the fifth, all-electronic interchange on the Tollway’s system. In 2015, work included the construction of two new ramps to carry traffic to and from the west to complete the full-access interchange and included all-electronic toll collection. Coupled with the reconstruction of the Irene Road Bridge, the project cost for the three new ramps is $13 million. This project was coordinated with the city of Belvidere, Boone County, IDOT, and Flora Township.
