St. Charles County, MO – Drivers in St. Charles County should plan for overnight closures on Route Z under Interstate 70 next week as construction crews continue work on the Improve I-70 project.
According to the Missouri Department of Transportation (MoDOT), Route Z will be closed overnight Monday, September 8, from 10 p.m. to 5 a.m. while crews pour the bridge deck driving surface. All entrance and exit ramps at Route Z will remain open during this work.
MoDOT officials said the closure is part of the ongoing Improve I-70 Warrenton to Wentzville Project, which aims to enhance safety and traffic flow along the busy interstate corridor. The agency noted that all work is weather permitting and may be rescheduled if conditions are unfavorable.
Drivers are encouraged to use alternate routes or allow extra time for travel through the area during the closure. Message boards and detour signs will help guide motorists around the work zone.
The $2.8 billion Improve I-70 program is one of Missouri’s largest transportation initiatives, addressing congestion, bridge repairs and road improvements along more than 200 miles of the interstate. The Warrenton to Wentzville stretch has been identified as a critical section due to heavy traffic volumes and continued growth in St. Charles County.
Motorists can stay up to date on closures, detours and project updates by visiting MoDOT’s traveler information map or following the agency’s official social media channels.
