Illinois Tollway I-88 Ramp Reconstruction

This project is the ISTHA's first application of precast reinforced concrete panels on a continuous section of multiple-lane ramp. 178 precast panels were placed at the I-88 eastbound exit ramp at Highland Ave. and the westbound entrance and exit ramps at Spring Road. Up to three lanes of panels replaced 50-year old pavement, negotiated turn lane radii, met end and side constraints, and provided profile and cross slope improvements. Work was accomplished overnight with lane closures only, and all lanes were open to traffic every day. The project successfully minimized inconvenience to motorists destined for major nearby retail shopping centers.
