UT NP ARCH 100(2) - Cross Sections-Schedule A.pdf

This is a Cross Sections technical drawing document (Schedule A) for the UT NP ARCH 100(2) Bridges on Delicate Arch Road project within Arches National Park. The document provides detailed engineering cross-sectional views and specifications for the three concrete bridge structures to be constructed across Salt Valley Wash, Salt Wash, and Winter Camp Wash. The cross sections illustrate the roadway profile elevations, bridge span dimensions (100-foot spans), embankment construction requirements, and drainage accommodations needed to support a 10-year design frequency flood event while allowing medium-sized excavator access to each wash for maintenance purposes.

The drawing specifications support the overall project scope, which includes reconstruction (4R) work with one restoration (3R) segment, roadway realignment at Salt Valley Wash, and pavement overlay work. The cross sections detail the structural and geometric requirements for embankment construction (10,000 cubic yards), riprap placement (1,725 cubic yards), roadway aggregate installation (5,140 tons), and asphalt concrete pavement overlay. This Schedule A document serves as a critical technical reference for contractors bidding on or executing this Federal Highway Administration project, providing the engineering baseline necessary for accurate cost estimation and construction compliance with the project's design standards and safety requirements for visitor access along this principal park road.
