I-57/I-64/IL 15 in Mt. Vernon Interchange Project

The Illinois Department of Transportation (IDOT) is performing a Preliminary Engineering and Environmental Study to study alternatives for improvements to the Interstate 57/64 at IL Route 15 Interchange in Mt. Vernon, Illinois. The project study area is as follows: I-57/64 split (approximately 0.8 miles north of IL Route 15) to north of Veteran’s Memorial Drive and on IL Route 15 from Davidson Avenue to 42nd Street.

The proposed project will involve a detailed study of transportation issues within the project area, while integrating community concerns through an open and comprehensive planning process. Mount Vernon is at the crossroads of two major interstates as well as a major arterial route. The north-south I-57 connects Chicago and Memphis (via I-55 in Missouri), the east-west I-64 connects St. Louis and Louisville, and IL Route 15 is an east-west Illinois State highway. Previous engineering studies completed for the I-57/64 and IL 15 Interchange have shown the need for improved access to and from I-57/64 and IL Route 15 by increasing capacity and reducing accidents.

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.
