During construction, 140th Street over I-49 will be closed. All local traffic will be detoured. Signed detours will be provided using the outer roads, and available cross streets:
- Westbound 140th St. traffic will be routed north on the East Outer Road to cross I-49 at Main St. and then back to 140th St. via the West Outer Road.
- Eastbound 140th St. traffic will be routed south on the West Outer Road to MO Route 150, then back to 140th St. via White Ave and the East Outer Road. I-49 will remain open with the exception of a few weekends for the demolition of the bridge and setting of girders. Additionally, there will be lane restrictions on I-49 for the construction of retaining walls and end bents. The project is scheduled to be completed in August 2020.
This bridge is included in Governor Mike Parson’s $351 million Focus on Bridges Program, which will repair or replace 250 bridges across the state.
