US 550 Red Mountain Pass Crib Wall Repairs Complete for Season 1
OURAY & SAN JUAN COUNTIES – The Colorado Department of Transportation and contractor Rock & Company have completed work for the season on US 550 Red Mountain Pass. The project, which began last July, is repairing/reconstructing five crib walls (retaining walls) below US 550 on Red Mountain Pass. The estimated total cost of this work (from design through construction) is $5.7 million. This is a two-season project that wrapped up early this year (the estimated season-one completion date was November 15, 2015), and will likely resume in mid-April and run through late June 2016, weather permitting.
The work consists of repairing and replacing crib walls at the following work sites:
-
Site 1 MM 79.5 to MM 79.4 – Just south of Red Mtn. Pass summit, 9 miles north of Silverton (RESUMES SPRING 2016)
Rock excavation and blasting, retaining wall construction (spring/summer 2016 impacts will be single-lane, alternating travel through the work zone)
-
Site 2 MM 88.5 to 88.6 – Approx. 4 miles south of Ouray near the snow shed (COMPLETE)
Excavation, culverts, retaining wall construction, minor paving
-
Site 3 MM 89.5 to MM 89.7 – Approx. 3 miles South of Ouray (COMPLETE)
Excavation and roadway stabilization that includes installation of a concrete “cap” or slab over the crib wall, drainage improvements and paving
This stretch of US 550 receives an average annual daily traffic count of 2,164 vehicles a day. The repair project will improve the safety and integrity of the highway by reinforcing these under-highway slope-side walls.
