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

The Illinois Department of Transportation (IDOT) initiated a preliminary engineering and environmental study (“Phase I”) for IL 7 from 131st Street to south of 135th Street in the Villages of Orland Park and Palos Park in Cook County.  IL 7 has been closed multiple times due to floodwater on the pavement.  The general scope of work for this improvement is anticipated to consist of drainage and roadway improvements that increase the level of flood protection along IL 7.  This improvement is included in the Department’s FY 2017-2022 Proposed Highway Improvement Program.  Our current engineering efforts are targeted to enable a 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.

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.

An open house public meeting was held to discuss the need for the improvement, to present the proposed improvement plan and required land acquisition, and to obtain public input. The following materials were presented at the meeting:
