Jane Addams Memorial Tollway (I-90) Reconstruction

As part of the Illinois Tollway’s $1.6 billion reconstruction of the I-90 East Corridor from the Elgin Toll Plaza to the Kennedy Expressway, our team was responsible for performing Phase I master planning and Phase II design engineering services for the widening and reconstruction of 6.5 miles of Jane Addams Memorial Tollway (I-90). Improvements included a fourth travel lane in each direction, a widened inside shoulder, the reconstruction of three crossroad bridges and two mainline bridges, the full reconstruction of two interchanges (at IL 25 and IL 31), as well as the partial reconstruction of two interchanges (at Beverly Road and IL 59). The project also included the reconstruction of five ramp toll plazas, the installation of retaining walls and noise abatement walls, the implementation of Intelligent Transportation System (ITS) infrastructure, and the relocation/protection of existing utilities, resulting in improved travel conditions.
