A Tuesday crash involving up to 70 vehicles on Interstate 70 eastbound is believed to have primarily been caused by wet, heavy snow, authorities said Wednesday.

The crash, which occurred just east of the Eisenhower Tunnel around 3 p.m. Tuesday, injured 19 people, eight of whom were hospitalized, Colorado State Patrol said in a Wednesday evening news release. Of those eight, only one sustained serious injuries. No one was killed in the crash.

Areas around the crash site received as much as eight inches of snow between Monday and Wednesday night, according to the National Weather Service.

That accumulation, vehicles driving too fast for the conditions, following others too closely and having insufficient tires, are all believed to have been factors in the crash, CSP said. No citations for the incident have yet been issued.

Authorities towed about 40 vehicles, including commercial vehicles, trailers and passenger vehicles, from the crash site to the Loveland Ski Basin parking lot, CSP said. An estimated 20-30 more involved in the crash were able to be driven from the scene.

Those who were not injured were taken to the Loveland Ski Basin Lodge via shuttle bus while responders cleared the scene, CSP said. The roadway was reopened to traffic just after 8 p.m. Wednesday.

Colorado is expected to receive additional snowfall through the end of the week, with some areas of the state receiving as much as eight inches by Saturday, according to the National Weather Service.
