St. Charles County, MO – A crash shut down all westbound lanes of Interstate 70 near Route 79 Friday, creating major traffic backups in St. Charles County.
According to the Missouri Department of Transportation (MoDOT), the closure went into effect just past Route 79, with no immediate estimate on when the highway would reopen. Crews remain on scene, but traffic is at a standstill heading westbound toward Wentzville.
Motorists are being advised to avoid the area and seek alternate routes, including Route 370 or Route 364, to bypass the closure. Drivers already in the area should expect extended delays.
Traffic crashes on I-70 are common due to the heavy commuter and freight traffic that uses the corridor daily. The interstate is a major east-west route across Missouri, connecting the St. Louis metro with communities throughout the state.
No details on the number of vehicles involved or injuries have been released. Emergency responders continue working the scene.
MoDOT urged drivers to check travel conditions on their online traveler map and to use caution in the area while detours remain in place.
