I-88 Reagan Tollway Roadway and Bridge Rehabilitation

Illinois State Toll Highway Authority

This project included the rehabilitation of approximately 13 miles of the Reagan (I-88) Tollway from Illinois Route 250 to Annie Glidden Road. 2IM Group developed a Phase I report for drainage improvements, erosion rehabilitation, and barrier warrant analysis and Phase II plans and specifications.

The Reagan Tollway consists of two-lane expressway of asphalt pavement. The rehabilitation of I-88 included resurfacing of the toll way pavement. Barrier Warrant Analysis (BWA) by 2IM Group included cross-section analysis which reviewed alternative designs to reduce guardrail length by flattening foreslopes.
