PROJECT NUMBER: UT NP ARCH 100(2)

PROJECT NAME: Bridges on Delicate Arch Road

PROJECT DESCRIPTION:

Delicate Arch Road (DAR) is within Arches National Park (Park) and provides access to

Delicate Arch. DAR is a functional class 1 roadway (Principal Park Road) and is heavily

traveled by visitors and often congested during periods with moderate-to-high levels of

visitation.

DAR crosses three low-gradient ephemeral washes (Salt Valley Wash, Salt Wash, and

Winter Camp Wash) near their confluence in the Salt Wash Basin downstream of Wolfe

Ranch. Culverts installed during original road construction in the mid-1990s and during

subsequent upgrades are inadequate to allow unobstructed stream flow and sediment

transport downstream. This existing condition produces flooding and sediment

deposition, which creates unsafe conditions for visitors, triggers road closures, potentially

strands Park visitors, diminishes visitor experience of the Park, and generates high

operational costs associated with traffic management, visitor safety, and cleanup

operations.

SCOPE OF THE WORK:

This project will be designated as Reconstruction (4R) with one segment of restoration

(3R), and will design and construct 100’ span concrete bridges at the Salt Valley Wash,

Salt Wash, and Winter Camp Wash. The DA roadway profile at each Wash will be raised

to accommodate a 10-year design frequency and allow a medium-sized excavator to

access each wash. The DA will be realigned at the Salt Valley wash, moving the roadway

and new bridge location to the north of the existing roadway and drainage crossing. The

remaining 3R sections of the roadway will receive full depth reclamation (FDR) or

removal of pavement, including all parking areas, followed by a 4-inch pavement

overlay.
