GLENWOOD, Colo. (CBS4)– Traffic will begin traveling in both directions at the same time along Interstate 70 through Glenwood Canyon on Thursday afternoon.

Drivers will still follow a pace car through that stretch but traffic will be traveling in both directions starting at 4 p.m. Although delays have been high in the mornings and evenings, those are expected to ease up.

Rockfall mitigation will continue through Thursday with equipment flown in by helicopter. There will be some delays for drivers between 9 a.m. and 4 p.m. seven days a week. A 10-foot width restriction remains in place at all times.

“We’re hopeful that by opening the highway to 24/7 two-way travel, we will see an easing in the congestion that has been present during the single-lane configuration,” CDOT Region 3 Transportation Director David Eller said in a statement. “It’s important travelers understand that–just like any other construction project with traffic control–there will still be delays, some possibly exceeding an hour during peak travel times. The reason we still need to control traffic with pilot cars is safety. We want to keep speeds low in this head-to-head configuration, and we need to be able to hold traffic when necessary to continue our work. When winter comes back to the canyon, we’ll also need to run snow plows without the hinderance of cones or other delineation in the middle of the road.”

Eastbound traffic is reduced to one lane at Exit 116, Glenwood Springs, all the way to Grizzly Creek rest area where the pace car picks up traffic. Westbound traffic is reduced to one lane at Exit 129, Bair Ranch, all the way to the east side of Hanging Lake Tunnel where the pace car picks up traffic.

The Grizzly Creek, Hanging Lake and Shoshone rest areas will be closed for the duration of the pace car operations. Bair Ranch and No Name rest areas will remain open. The Glenwood Canyon Bike Path remains closed as well.
