IL 7 from 131st Street to south of 135th Street

The Illinois Department of Transportation (IDOT) is nearing completion of a preliminary engineering and environmental study (Phase I) for the improvement of IL 7 from 131st Street to south of 135th Street in the Villages of Orland Park and Palos Park in Cook County.  The scope of work consists of drainage and roadway improvements that increase the level of flood protection along IL 7.  This improvement is included in IDOT’s FY 2019-2024 Proposed Highway Improvement Program.  Current engineering efforts are targeted to enable a contract letting in the middle years of the multi-year program contingent upon plan readiness, land acquisition, and funding availability through future annual legislative appropriations.

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.
