I-55 Corridor Improvements Project
The I-55 Corridor Improvements project area includes the cities of Pevely, Herculaneum, Festus, and Crystal City. The purpose of this project is to address traffic and safety concerns along the I-55 corridor and account for future development and growth patterns in the region.
During the first phase of the project, The Missouri Department of Transportation’s (MoDOT) St. Louis District, in conjunction with the Federal Highway Administration, conducted a conceptual study along Interstate 55, from the Route Z interchange to the U.S. 67 interchange in Jefferson County. The next phase of the project involves preliminary design of the recommended alternative, additional study of traffic patterns, safety, roadway conditions, noise analysis, and environmental documentation. The final phase of the project is the design/build.
PROJECT GOALS
- Deliver the project within the program budget ($246 million).
- Maximize reliability and safety on I-55 and U.S. 67.
- Provide a durable and maintainable transportation system compatible with regional development.
