GLENWOOD SPRINGS — Interstate 70 in Glenwood Canyon is closed in both directions Tuesday morning due to a rockslide just west of Grizzly Creek. The Colorado Department of Transportation and Colorado State Patrol expect I-70 to be closed through the canyon for most of day and possibly longer.

CDOT  reported the rockslide on Twitter at about 1 a.m., and said in a 6 a.m. news release that there is no timeframe on when the road will be opened.

CDOT spokeswoman Tracy Trulove said no vehicles were involved, and there were no injuries.

“There is a significant amount of debris on westbound deck, and some damage to retaining wall,” she said. “Our geohazards team is on the way to assess the damage.”

I-70 is closed at the main Glenwood Springs exit 116 on the west, and at Dotsero (mile marker 133) on the east side of the canyon.

In a Twitter post, the Colorado State Patrol suggested an alternative route of Colorado Highway 131 (Wolcott) to U.S. Highway 40 (Steamboat Springs) to Colorado Highway 13 (Rifle).

Motorists are advised that the northern detour via U.S. 40 is a 203-mile alternate route that will take about three hours and 50 minutes to travel, according to CDOT.

“This detour adds 146 miles and about three hours to a regular trip from Wolcott to Rifle on I-70,” according to a CDOT news release.

The stretch of I-70 through Glenwood Canyon is prone to rockslides, in particular the section west of the Hanging Lake Tunnel. A major rockslide on Feb. 15, 2016, resulted in a near weeklong closure in both directions and lengthy detours north via U.S. 40 and south along U.S. Highway 50. The canyon was open to one lane only in both directions after six days, but using a pilot car to guide traffic in alternating fashion for several weeks. I-70 through the canyon was not fully reopened until the middle of April that year, after some $5 million in emergency repairs.
