Death Valley Route 11 also known as Bonnie Clare Road begins at the intersection of California State Highway 190 just south of the turn off for Daylight Pass Road and proceeds north then east to the Park Boundary at the Nevada state line. Bonnie Clare Road is located within Inyo County in southwestern California. The road is located within Death Valley National Park and is owned and maintained by the National Park Service.
On the evening of Sunday, October 18, 2015, a torrential storm dropped nearly 3 inches of rain in just five hours on the northeast section of Death Valley National Park. Floodwaters destroyed the road through Grapevine Canyon to Scotty’s Castle. This flood came on the heels of several other October flash floods, with cumulative damage effecting both the Scotty’s Castle and Badwater areas.
This scope of work is for the final design of portions of Bonnie Clare Road from the intersection with Ubehebe Crater Road (mile post 32.5), north east toward the Park boundary (mile post 41.25). In particular, the roadway required spot repairs to sections of the roadway that were damaged by the flood and full reconstruction from mile post 36 to 41.25. The total project length is 8.75 miles.
From mile post 36 to the water intake system east of Scotty’s Castle, the alignment was matched to the previously existing alignment. A section of roadway required full reconstruction at this location. The portion of road in Grapevine Canyon was realigned from the previous alignment up and out of the wash.
