47th Street at East Avenue

In January 2017, the Illinois Department of Transportation (Department) completed a preliminary engineering and environmental study (Phase I) for the proposed improvement of 47th Street at East Avenue in Cook County.

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.

The scope of the project includes installation of traffic signals, upgraded railroad crossing gates, new pedestrian crossing gates, pavement marking, installation of sidewalks, and drainage improvements within the project limits.  Storm sewer pipe sizes will be increased along the east and south legs and will continue to the McCook ditch.

This improvement is included in the Department’s FY 2018-2023 Proposed Highway Improvement Program. Our current engineering efforts are targeted to enable a contract letting in the early years of our current multi-year program contingent upon plan readiness, land acquisition, and funding availability through our future annual legislative appropriations.


The Department is interested in hearing from you. If you have questions about the project, please fill out the feedback form or contact us at:

The following documents illustrate the proposed improvements at the conclusion of Phase I including crash data, project map and a presentation highlighting the Phase I design process for this project.

IDOT is currently in the contract plan preparation and land acquisition phase (Phase II) of the project. This improvement is included in the Department’s FY 2017-2022 Proposed Highway Improvement Program. As we make changes, this website will be updated accordingly.
