A truck pulling a trailer caught fire closing the westbound lanes of Interstate 70 near Bakerville.
The fire was reported shortly before 9:30 a.m. Saturday.
The driver was able to pull into a chain-up area but the smoke and the presence of propane tanks forced emergency crews to close the lanes, according to Trooper Alisha Danko with the Colorado State Patrol.
No one was hurt in the fire.
One lane reopened within 30 minutes and all lanes reopened in about an hour.
