OURAY COUNTY – US 550 over Red Mountain Pass will remain closed at least through the weekend, due to continuous rockfall and the risk of more at MM 90, two miles south of Ouray. There is currently no estimate for a reopening of the pass beyond this weekend, though more will be known by Friday as mitigation work gets underway. Motorists are urged to stay updated by going to www.cotrip.org or signing up for road condition messaging through CDOT’s web site (see below).
ALTERNATE ROUTE: The alternate routes are the following: From Ouray to Durango (a distance of 70 miles using US 550) motorists will instead use SH 62 from Ridgway over Dallas Divide, SH 145 over Lizard Head Pass, then US 160, for a trip of 168 miles (a 98-mile detour). The average daily traffic count on Red Mountain Pass is 2,200.
Today, CDOT crews and rockfall contractor Yenter Companies assessed the sight, from land and from helicopter, and the decision was made to keep the highway closed until loose rock can be removed.
“We do not have easy alternate routes here in southwest Colorado and there is a hardship any time we close this pass,” CDOT Region 5 Transportation Director Kerrie Neet said. “It’s important for travelers and surrounding communities to know we don’t make these decisions lightly; we base them on the safety of the traveling public, as well as our workers.”
Tomorrow (Wednesday) San Miguel Power will remove the downed power pole as well as loose wire on the mountainside. Thursday and Friday, Yenter Companies plan to conduct work to bring the loose rock down from 900 feet above the roadway—more details on Yenter’s work will be provided at that time.
