A fiery crash that shut down Interstate 70 in Vail on Wednesday involved two semi-trailers, an officer with the Vail police department has confirmed.

Sergeant Rebecca Anderson responded to the accident and said while it’s still under investigation, it appears that one semi-trailer was stopped in traffic, headed eastbound, when it was hit from behind by another semi-trailer.

“The tractor of the semi which hit the stopped semi immediately started on fire,” Anderson said. “The fire then spread to the trailer on the same semi.”

The incident took place just after 6 p.m., shutting down I-70 for more than two hours while crews worked to contain the blaze. By 6:19 p.m., both the westbound and eastbound lanes of the interstate were shut down along with South Frontage Road in Vail. South Frontage Road reopened at 7:06 p.m., allowing traffic to travel east on South Frontage Road to detour around the closure.
