MORRISON, Colo. (CBS4)– Colorado State Troopers closed eastbound lanes of Interstate 70 at Lookout Mountain for several hours after a semi blocked one of the runaway truck ramps.
One lane of the eastbound lanes of I-70 opened at 6:35 p.m. Thursday. The other lane remained closed until nearly 9 p.m. The backups during the evening commute stretched for miles.
The semi was carrying seven totes each filled with 550 gallons of flammable material. About 400 gallons spilled. Hazardous materials crews were able to stop the leak. The semi driver suffered minor injuries.
Traffic was diverted off to U.S. 40 to Highway 8 and then back to I-70.
Eastbound lanes of U.S. 6 in Clear Creek Canyon were opened to help with the traffic flow. Clear Creek Canyon has been closed during the week while Colorado Department of Transportation crews install fiber optic line.
Once I-70 reopened Clear Creek Canyon closed again. Westbound lanes of U.S. 6 remained closed. Both directions will stay closed until Friday at 10 a.m.
