The left lane of westbound Interstate 70 closed Thursday morning after a FedEx truck rolled over on the side of the highway.
The crash happened at milepost 201, near Frisco.
Colorado State Patrol says drivers should expect the lane to remain closed for several hours as they work to clean up the crash.
There’s no word yet on what caused the truck to roll over.
CSP hasn’t said if the driver or anyone else was injured.
