The Missouri Department of Transportation has announced traffic shifts on Interstate 70 between Warrenton and the Wright City rest area (mile marker 194.2 to 197.6) on Monday, July 27.
Traffic will shift onto the newly constructed lanes to allow crews to construct the permanent driving lane as work continues on the Improve I-70: Warrenton to Wentzville project. To complete the traffic switch, an extended overnight left-lane closure will occur from 7 p.m. on Monday, July 27, through 2 p.m. on Tuesday, July 28.
After the traffic switch occurs, traffic barriers will be in place along the right and left shoulders of eastbound I-70 for these areas. Designated emergency pull-off areas will be available and adjusted as work progresses. Two lanes of traffic will be maintained on I-70 during peak travel times and the speed limit will remain 55 mph throughout the work zone. Westbound I-70 will have intermittent nighttime left lane closures during this time.
At times, the eastbound I-70 construction area may be accessed from parallel sections of Veterans Memorial Parkway. Travelers can anticipate intermittent lane closures on Veterans Memorial Parkway for the movement of equipment and materials. Flaggers will be utilized for traffic control to guide motorists through the work zone on Veterans Memorial Parkway.
The above traffic impacts are scheduled through fall 2026. Motorists are encouraged to pay attention in work zones, drive the posted work zone speed limit, and allow extra time for travel, MoDOT said. All work is weather-dependent, and schedules are subject to change.
