Canyon closures postponed

Hourly closures of Interstate 70 in Glenwood Canyon that had been scheduled for today have been postponed until Tuesday, Oct. 6, the Colorado Department of Transportation said.

The closures are for helicopter operations as work continues on I-70’s westbound lanes between Grizzly Creek, Mile Marker 121, and Hanging Lake Tunnel. During the work, a helicopter will be lifting 1,200 pounds of rockfall fencing materials into place between 100 feet and 400 feet above the stretch of road, which is prone to slides.

When the work gets done, CDOT anticipates between five and seven stops during the day, each lasting less than 20 minutes. The stops will occur approximately every hour beginning shortly after 8 a.m. Pedestrians also will be stopped along the Glenwood Canyon bike path.

Drivers are asked to be aware that the helicopter will be operating in Glenwood Canyon several hundred feet above the road. During these times, traffic will remain open. CDOT advises drivers to remain focused on the road and follow all traffic regulations in the work zone.

Traffic will be stopped only when the helicopter lands, primarily for refueling.

Drivers accessing the westbound lane between Grizzly Creek (MM 121) and Shoshone (MM 123), not mainline Interstate 70, are to expect a greater number of stops through the days the helicopter is operating.

This work is part of a $7.3 million project and has been under way all summer. In addition to rockfall fence replacements, the project includes bridge rail and bridge deck repairs.

CDOT would like to remind motorists that fines are doubled within the work zone. If you have questions or concerns about this project, call the project hotline at 970-930-8009 or email
