BOULDER - US 36 is back open between Lyons and Pinewood Springs. It was closed for awhile on Monday due to rockfall mitigation.
Earlier Monday no traffic was allowed from noon to 3 p.m. on Monday on U.S. Highway 36 near mile marker 17.6, which is west of Pinewood Springs and southeast of Estes Park, according to the Colorado Department of Transportation.
Detours were in place, but CDOT expected major delays.
CDOT strongly recommended the use of US 34 between Loveland and Estes Park, and S.H. 7 between Estes Park and Lyons as alternate routes for those who can use them.
Due to this and other projects on U.S. 36 CDOT says to expect major delays between 8 a.m. and 4 p.m. daily.
Monday's three-hour closure is just the second of 20 different three-hour blasting operations that are part of the U.S. 36 Emergency Flood Reconstruction project between Lyons and Estes Park.
In addition to the 20 three-hour closures, the project will require 10 different two-hour closures, and 10 different night-time closures.
CDOT described Monday's blasting work being done in a press release issued last week:
"During blasting activities, crews will be loosening sections of the mountainside and then removing the loosened materials from the roadway. On average, the highway will be moved inland away from the river 20 feet, with the range varying between five feet to 50 feet. Altogether, an expected 210,000 cubic yards of material is expected to be removed (the equivalent of 210,000 dishwashers). The materials will be recycled and used to not only stabilize the embankment below the highway, but will also be used to stabilize the river channel. Leftover materials will be donated to other area reconstruction projects underway by towns and counties still recovering from the flood, including the County Road 80 (Longmont Dam Road) project underway by Boulder County and the city of Longmont. Unfortunately, no materials will be available for donation to private citizens."
