It also created major traffic problems. Emergency crews shut down both lanes of Interstate 70 going through the canyon while officials investigated the crash and worked to clean up gas that spilled from the semi.

Officials with the Colorado State Patrol said one of the people hurt was a boy and that he was flown to a hospital in Denver after initially being brought to the hospital in Vail. The two other people who were injured — a man and a woman — were being treated at Vail Valley Medical Center.

In that area of the canyon Interstate 70 is currently down to one lane in each direction due to construction. The lanes reopened early Wednesday afternoon. The Glenwood Canyon Bike Path is expected to remain closed for several days due to the cleanup effort.
