Welcome to the U.S. Route 20
at Marengo Road Study
In May of 2016, The Illinois Department of Transportation (Department) completed preliminary engineering and environmental studies (Phase I) for the improvement of the US 20 intersections with Marengo Road/Beck Road and South Union Road located in Coral Township, McHenry County. The project has advanced to Phase II of the project development process which involves land acquisition and the development of detailed construction documents for the public bid process. 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.
