A pileup involving more than 50 vehicles forced the closure of a road in Denver on Thursday night, police said.
"Officers are on-scene with a large-scale weather-related, multivehicle crash," the Denver Police Department tweeted. The crash occurred on eastbound 6th Ave. at the Interstate 25 interchange.
There were injuries reported but none were life-threatening, police said. They did not provide details on the number of people injured or the nature of the injuries.
The cause of the crash was unclear. Police urged drivers to avoid the area as they worked to clear the scene.
Temperatures in Denver hovered around 28 degrees overnight with light snow and a foggy mist.
"Heavy snow and hazardous travel conditions will persist over portions of the central and southern Rockies into Friday before diminishing," the National Weather Service said.
