U.S. 6 over Loveland Pass was closed for several hours Sunday after a mudslide near Arapahoe Basin covered much of the roadway in mud and debris Saturday night, the Colorado Department of Transportation said.

The popular mountain pass was expected to be closed all day and “probably longer,” but the department said it reopened just before 2 p.m.

Travelers were advised to use the Interstate 70 through the Eisenhower Tunnel as a detour.

Crews worked to clear the roadway, officials said. Hazmat vehicles were escorted through the Eisenhower Tunnel at the top of each hour. Regular traffic was stopped periodically to allow for hazmat vehicles to pass.

This is the second weekend in a row that mudslides have closed U.S. 6 over Loveland Pass. Last weekend, a mudslide struck near Arapahoe Basin forced the pass to close for about 48 hours.

Interstate 70 has also been hit hard by mudslides in recent week, resulting in regular closures.

On Thursday, mudslides spilled onto I-70 in about 10 locations, forcing 108 people to spend the night in Glenwood Canyon. I-70 will remain closed in Glenwood Canyon through the weekend, officials said.

A mudslide also closed Colorado 125 north of Granby in Grand County on Sunday, according to the department.
