Retaining Wall Work on US 550 Red Mountain Pass

July 13, 2012 - Southwestern Colorado/CDOT Region 5 - 2 remaining night closures planned: July 17 and July 23.

OURAY COUNTY – Colorado Department of Transportation contractor Midwest Rockfall will require at least one more night closure of US 550 Red Mountain Pass for drainage pipe work. The drainage work is part of the project to repair two crib walls (retaining walls) under the southbound lane approximately 1.5 miles north of snow shed. The work will be completed by September 25, 2012.

NIGHTTIME TRAVEL IMPACTS: The highway was closed overnight on July 12. Pipe work will require two more nights of closures:  one, on July 17, which was previously planned; and another, on July 23. On these two nights the pass will be closed from 8 p.m. to 6 a.m. to allow crews to remove and replace two inlets (a maximum of six nights of closures are allowed but will likely not be needed). Following this work, another announcement will be sent to confirm whether or not any future nighttime closures are necessary. The contractor may have up to six nights (total) of closures but it is not likely work will require that.

Regular travel impacts: Through September 25, motorists will encounter single-lane, alternating traffic between 7 a.m. and 7 p.m., Monday through Friday. There will be no weekend work. Motorists will also encounter periodic full traffic holds in both directions of up to 15 minutes during work hours (while equipment is in the roadway). Please note, while these traffic holds will be limited to 15 minutes or less, motorists’ actual delays will exceed 15 minutes, as the traffic queues are cleared in each direction. Delay times will vary depending upon traffic volumes.
