Districts Impacted
What is the current situation?
MoDOT will be making multiple road and bridge improvements along I-44 between Eureka and Valley Park in St. Louis County to take care of the existing interstate system. Work includes repairing pavement along the corridor to improve reliability and avoid costly replacement in the future. Bridge and culvert structures along the corridor need rehabilitation or preventative maintenance, while some structures nearing the end of their life cycle require a full replacement. Existing median barriers also need to be replaced to meet current standards. Improvements will help keep the roadway safe and operational for the foreseeable future.
What work will be completed as part of this project?
- Fixing the pavement and roadway surface where needed along I-44 between Eureka and Valley Park.
- Repairing several bridges on I‑44.
- Replacing the I-44 bridges at Williams Creek.
- Improving culvert structures on both sides of Williams Creek.
- Rebuilding the interstate median barrier.
- Adding safety improvements at Antire Hill.
How is the project being funded?
MoDOT is spending more than $65 million on these pavement, bridge, and safety improvements along I-44 in southwest St. Louis County. The project is funded through legislatively designated funds, the Statewide Transportation Improvement Program (STIP) and Safety Improvements Funding. This work will improve this section of I-44 for everyone using it, now and in the future, while ensuring the ongoing safety and reliability of our infrastructure.
What is Forward 44?
Forward 44 is an initiative by the Missouri Department of Transportation aimed at improving Interstate 44, a vital east-west link that has been a key freight corridor since its completion in 1966. The initiative addresses outdated design standards and safety components, ensuring that this vital route continues to meet both statewide and national transportation needs.

Project timeline (tentative)
MoDOT and its consultant review the roadway, evaluate the work needed to maintain the existing system and creates a plan to share with the community.
MoDOT will holds an open house style public meeting for the community to view project information, ask questions, and provide feedback. This information remains available to view and to comment upon until May 26, 2026.
Once the plans are finalized, the contract is put out for bid and the Missouri Highways and Transportation Commission awards the contract to the contractor with the lowest qualified bid.
Once the contract has been awarded work can begin on the project. Main construction impacts/lane closures are expected in 2027 and 2028 with some completion activities scheduled for 2029.
