Rockfall Update - US 550 Red Mountain Pass

January 29, 2014 - Southwestern Colorado/CDOT Region 5 - Crews have installed 32 rockfall netting panels over the past three days, work continues tomorrow before the storm hits.

OURAY COUNTY – As reported earlier today, crews installed four more rockfall nets for a total of 36 now on the slope. Crews then worked to complete fastening them together prior to the storm. Some significant rock scaling was also completed. With the storm headed in, bringing up to 2 feet of snow by the weekend, crews will carry out any necessary follow-up mitigation as weather permits.

Tomorrow, 600 feet of concrete barrier will be brought in—400 feet will serve as a base for rockfall fencing that will be set along the inside of the highway center line, effectively closing the northbound lane in the rockfall zone (there will be 100 feet of barrier on either end for a taper). This fencing will serve as a temporary safeguard, enabling CDOT to initially open a single lane through this area.

Announcement of a reopen plan could come tomorrow, but hinges on a site assessment and weather conditions.
