DENVER -- Several Colorado highways were closed as a snowstorm moved through Colorado late Thursday afternoon.
Interstate 70
I-70 at mile marker 259, north of Morrison, was closed eastbound due to several spun out vehicles and crashes. A Colorado Department of Transportation (CDOT) camera was able to capture the moment two people were helping a driver get out from the left-hand shoulder of the highway.
Eastbound I-70 reopened at Genesee Park at around 5:50 p.m.
The Colorado State Patrol - Golden division said westbound I-70 was closed from Golden to Genesee due to the heavy snow and arctic winds. The highway reopened at around 6:08 p.m., according to CSP Golden officials.

Northbound Highway 93 was also closed from Golden due to "multiple slide offs and crashes," the CSP Golden division said in a tweet. A CSP car was hit, according to officials. There were no injuries from this crash, according to CSP spokesman Josh Lewis.
US 6
US 6 was closed at Clear Creek Canyon Tunnel No. 3 due to a crash. CDOT officials are advising travelers to expect delays in the area.
