St. Charles County, MO – Motorists traveling on Interstate 70 near Foristell can expect changes starting this Thursday as crews with the Improve I-70 Warrenton to Wentzville Project begin installing barrier walls on both the eastbound and westbound shoulders.
According to the Missouri Department of Transportation (MoDOT), the work at the Foristell interchange is scheduled to begin July 10, weather permitting, and will impact both directions of I-70. The installation marks the first phase of a major infrastructure improvement aimed at accommodating a future third lane in each direction.
MoDOT stated that while the barrier wall installation is underway, all lanes on I-70 will remain open and maintain the standard 12-foot width. Crews will be working behind the barrier wall to start construction on new bridges for the Foristell interchange. The speed limit in this work zone will be reduced to 60 miles per hour for the duration of the project.
This project is part of the broader Improve I-70 initiative between Warrenton and Wentzville, covering the eastern section of Interstate 70. MoDOT awarded the project in November 2024, with full-scale construction slated for 2025-2028. Motorists are encouraged to stay alert in the area and allow extra time for travel as work continues.
