US 52/IL 64 over the Mississippi River

The Illinois Department of Transportation (IDOT) has undertaken the U.S. 52/IL 64 over the Mississippi River Study. IDOT is the lead agency with input being provided by The Iowa Department of Transportation (IADOT). This study is examining transportation needs and solutions for the replacement of the existing bridge that carries U.S. 52 over the Mississippi River between Savanna, Illinois and Sabula, Iowa. The project also involves the reconstruction of IL 84 at the north end of Savanna, Illinois. The study includes a public involvement process, and includes opportunities for stakeholder input and feedback.

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.
