SUPERIOR, Colo. -- Both directions of U.S. 36 reopened Friday after being closed for two hours because of six accidents involving 39 vehicles, including a semitrailer, the Boulder County Sheriff's Office said.
The biggest accident was a 12-vehicle chain-reaction crash at about 6:45 a.m. that forced the closure of eastbound U.S. 36 at Table Mesa in Boulder. The accident was close to the McCaslin Boulevard exit.
Two other crashes forced westbound U.S. 36 to be closed at Flatirons Crossing in Broomfield but it reopened at 9 a.m. Eastbound traffic reopened about 9:45 a.m.

One vehicle in the 12-vehicle chain-reaction crash was pinned under the semitrailer. The driver was able to safely get out of the car.
There were no serious injuries reported in any of the accidents. Three people were taken to hospitals to be treated for minor injuries.
The vehicles were towed to the Target parking lot in Superior where one driver said the lot was a "carnage of cars."
"It's pretty impressive," a patrolman told the Boulder Daily Camera.AlertMe
