St. Charles County, MO – Drivers traveling along Interstate 70 near Route Z should plan for overnight delays starting Monday evening as crews begin concrete pavement repairs in the area.
According to the Missouri Department of Transportation (MoDOT), work will affect both eastbound and westbound I-70 lanes near mile marker 209, just east and west of the Route Z bridge. All work is weather permitting.
On Monday night, December 22, crews will close one eastbound I-70 lane just east of the Route Z bridge from 6 p.m. to 6 a.m. Motorists should expect reduced speeds and potential slowdowns during the overnight hours.
Additional impacts are scheduled for Tuesday night into Wednesday morning, December 23, when one westbound I-70 lane just west of the Route Z bridge will close from 8 p.m. to 8 a.m. During this closure, the left lane of eastbound I-70 will also temporarily close from 8 p.m. to 2 a.m. to allow concrete trucks to safely enter and exit the work zone.
MoDOT officials say the temporary closures are necessary to complete pavement repairs that help maintain long-term roadway safety and durability along this busy stretch of interstate. Drivers are urged to remain alert, follow posted signage, and watch for crews working close to traffic.
Motorists traveling through St. Charles County, especially those commuting between the St. Louis metro area and points west, should consider allowing extra travel time or using alternate routes during the overnight work periods.
