Glenwood Canyon

Glenwood Canyon follows the Colorado River for 12.5 miles from Dotsero westward to Glenwood Springs. It passes through rock walls as high as 1,300 feet along the way. A section of Interstate 70 carves through the canyon and features 40 bridges, two 4,000-foot-long tunnels, and 30,000 tons of structural and reinforcing steel.

Closures have been scheduled on Colorado's popular Interstate 70 through Glenwood Canyon to repair damaged areas caused by the Grizzly Creek fire in late 2020, according to Colorado Department of Transportation.

Helicopter operations will require traffic holds on a stretch of I-70 periodically from April 12 to April 19, and again on April 21 and 22 if needed.

I-70 is popular for those heading into the mountains to destinations such as several ski resorts, Hanging Lake, and more.

Power poles are being replaced in Glenwood Canyon that were burned in the fire. The operations on April 21 will have helicopters assisting in rockfall fencing, which could continue on April 22 if needed, the transportation department said.

When the helicopter is airborne, traffic stops on Interstate 70 will be required for eastbound and westbound traffic. The traffic holds are expected to last up to 30 minutes.

Crews with Rock Solid Solutions have been working to install the rockfall barriers and fencing since December 2020. The fencing and barriers help protect against rockfall from the damage caused by the Grizzly Creek fire.

All work is weather dependent and the scheduled work and closures are subject to change. Check with CDOT's Travel Center for live updates on road conditions, closures, and more.

The scheduled closures are detailed from CDOT as followed:


On Wednesday, April 14, 15-minute traffic stops will take place to allow four power poles to be installed. Motorists should expect four traffic stops, taking place between 9:00 AM and 5 PM.


On Wednesday, April 21, 30-minute traffic stops will begin at 9:00 AM. The closures are for westbound traffic at mile marker 123.95 east of the Hanging Lake Tunnel bore and a rolling stop will be in place for eastbound traffic. Thirty-minute traffic stops may continue on Thursday, April 22, if necessary to complete work.

Continuing project impacts Monday - Friday: A westbound right lane closure from mile markers 119 to 125 in place, west of the Hanging Lake Tunnel bore, for fence work on the slopes above I-70.
