County Road 17 Rockfall Information

County Road 17 3 miles north of Ouray remains closed to ALL VEHICLE, PEDESTRIAN, EQUESTRIAN, AND BICYCLE TRAFFIC. The area is extremely dangerous due to rocks continuing to fall. 

Around 7:30AM on March 8, 2019 a massive rockslide damaged County Road 17, approximately 3 miles north of Ouray. A rock the size of two large SUVs landed on the surface of the road above the gas main that supplies the City of Ouray and Whispering Pines neighborhood.

Subsequently, Ouray County emergency officials, DOWL Engineering, and Black Hills Energy began to establish plans to install a temporary gas line; however, rocks were continuing to fall, endangering crews. (Click here to view the March 28, 2019 Press Release) Black Hills Energy crews were unable to install the temporary gas line until rock scaling could be performed. 

Ouray County was successful in securing $74,255 in emergency grant funding from the Department of Local Affairs (DOLA) to fund rockfall mitigation, removal of the rock, road repair, and reconstruction and repair of a retaining wall. Using the County's emergency procurement policy, the County retained the services of EarthTech West II to perform the rock scaling (by and through subcontractor), mitigation and repair of the retaining wall. 

On June 17 and 18 hillside reconnaissance was performed; areas for scaling were marked and equipment was moved into place. (Click here to view the June 24, 2019 update.)

Phase 1 assessment and scaling work was completed on Friday, June 28. Phase 2 work, including drilling, grouting, netting and tightening was completed on Monday, July 22. Black Hills Energy will be on site on Thursday, June 25 to expose the gas pipeline and determine methods for rock removal. The County and EarthTech West will be working to break and remove the rockfall debris and Black Hills Energy will fully replace the gas line in this area. Remaining work includes repair to the HIlfiker retaining wall and road rebuilding and grading. Expected completion is Friday, August 9th. (Click here to view the July 23, 2019 update.)

The road will remain closed to all traffic, including pedestrians and bikes, into August. (Click here to view the Project Schedule).
