LOUISVILLE, Colo. — Westbound U.S. 36 was closed on Tuesday morning after several vehicles encountered slick conditions and were involved in crashes, the Colorado State Patrol said.

A 12-car pileup was reported about 10:30 a.m. on U.S. 36 near the Foothills Parkway exit, though first responders could not at first determine if it was one crash or multiple crashes.
