Crews with the Improve I-70 Warrenton to Wentzville Project will close the eastbound Interstate 70 on ramp from David Hoekel Parkway (mile marker 206) for 30 days starting Thursday, July 23.
This closure is necessary to remove and construct the new eastbound I-70 lanes. All work is weather permitting.
Motorists are encouraged to pay attention in work zones, drive the posted work zone speed limit, and allow extra time for travel. All work is weather-dependent, and schedules are subject to change.
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.
