A section of Interstate 70 was closed after a multi-vehicle wreck in north St. Louis County on Monday.
The wreck happened on the interstate just past Jennings Station Rd. around 9:30 a.m.
All westbound lanes of the interstate were closed as it appeared semi trucks could not make it uphill the snow-laced interstate. Westbound Jennings Station Rd. was closed as well.
Additional information was not immediately available.
