Crews with the Improve I-70 Warrenton to Wentzville Project will close the eastbound Interstate 70 on and off ramps at the Route T/W interchange in Foristell overnight June 30 and July 1. All work is weather permitting.
The eastbound I-70 on-ramp will close Tuesday, June 30 from 10 p.m. to 3 a.m. to pave the new connecting lane and shoulder at the ramp.
On Wednesday, July 1 from 10 p.m. to 3 a.m., the eastbound I-70 off-ramp at the Route T/W interchange will close for the same paving work.
This work is part of the second project in MoDOT’s Statewide Improve I-70 Program. Improve I-70: Warrenton to Wentzville is a $600 million Design-Build project that will improve the 20-mile stretch of I-70 between Warrenton and Wentzville. The project was awarded to the Improve 70 Alliance team in November 2024. Construction is anticipated to be complete by the end of 2028.
