Cleanup on I-70 in Colorado continued into Thursday morning following 21-vehicle pileup

A massive 21-vehicle pileup on I-70 in Colorado during winter storm conditions forced the roadway closed on Wednesday, authorities said.

The accident involved nine semi-trucks and 12 passenger vehicles on I-70 near the Strasburg area, the Colorado State Patrol (CSP) said. 

Authorities said no injuries were immediately reported.

The agency shared photos of the trucks and cars scattered across the snow-covered road and others showing what they described as "whiteout conditions."

The multi-vehicle crash shutdown I-70 from Airpark to the Kansas line in both directions, CSP said. 

Officials warned travelers to expect an extended closure that could take until Thursday to clear due to high winds and slick conditions.
