Illinois 37 from Wildcat Drive to Illinois 148 south of Marion

Welcome to the project page for the Illinois 37 resurfacing project. The Illinois Department of Transportation is in the planning and early design stages (Phase I) for this road improvement. The project location is just south of Marion and consists of milling and resurfacing the existing two-lane road, constructing 8-foot shoulders (5-foot asphalt and 3-foot aggregate), grading new ditches, and extending or replacing culverts. The project will begin near Wildcat Drive and continue to the south, ending near Illinois 148. A northbound right-turn lane will also be constructed at Lake of Egypt Road. 

Please explore the web page for further information regarding the project. There are exhibits that include aerial renderings of the proposed project, proposed typical sections and crash exhibits of the existing road.

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.
