I-55 Corridor Improvements Conceptual Study in Jefferson County

The Missouri Department of Transportation’s (MoDOT) St. Louis District, in conjunction with the Federal Highway Administration, is conducting a conceptual study along Interstate 55, from the Route Z interchange to the Route 67 interchange in Jefferson County. The I-55 Corridor Improvements project area includes the cities of Pevely, Herculaneum, Festus, and Crystal City.

This initial phase allows MoDOT to understand the current corridor conditions and identify what improvements could be considered and implemented. The conceptual study will look at the existing safety, design standards, geometry, traffic congestion, bridge conditions, and utilities in the corridor. It will also consider local coordination, and future changes and growth in the area. In future phases, MoDOT will lead the project team through environmental clearance and preliminary design, final design, and construction.
