The Illinois Department of Transportation (Department) is currently engaged in preliminary engineering and environmental studies (Phase I) for the improvement of 55th Street from U.S. Route 12/20/45 (LaGrange Road) to East Avenue in the City of Countryside in Cook County. This improvement is included in the Department’s FY 2018-2023 Proposed Highway Improvement Program. Our engineering efforts are targeted to enable contract letting in the middle years of our current multi-year program contingent upon plan readiness, land acquisition, and funding availability through our future annual legislative appropriations. The Department remains committed to funding 40 million dollars in highway improvements in this area, including engineering, land acquisition, construction, and construction engineering of projects identified in the Joliet Road Feasibility Study. The general scope of work for this improvement is anticipated to consist of roadway widening and reconstruction to provide a continuous five-lane cross section along 55th Street and intersection improvements.

Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.
