The Colorado Department of Transportation has finished its 2-month-long cleanup effort in Boulder Canyon after a fuel tanker was involved in a roll-over accident in December.

Boulder Canyon Drive has been reduced to one lane by CDOT at the 34.6 mile marker 3 miles west of Magnolia Road while crews worked to clean up the area after a truck carrying 4,000 gallons of diesel fuel was involved in a roll-over accident at that site.

The work initially was only supposed to last until January, but CDOT said the cleanup took longer than expected due to the amount of fuel that spilled and then spread in a narrow section of the highway.

There may still be intermittent lane closures while CDOT finish the final work on the highway.

According to the Colorado State Patrol, speed and "driver inexperience" may have led to the crash on Dec. 2. The driver of the truck, Reed Kreutzer, of Thornton, was wearing a seatbelt and was not injured, but was cited for careless driving, according to the state patrol.
