A22 - Enclosure F - WKS Intake Tower Bridge Limits.pdf

This document is an attachment to a Scope-of-Work for underbridge access equipment and services required for inspection of bridges in the Wilmington District. Specifically, this attachment describes the W Kerr Scott Lake Dam Intake Tower Access Bridge located on the Yadkin River in Wilkes County, North Carolina. The bridge is a non-public, controlled access structure with a 126-foot span and 14-foot deck width accommodating a single 12-foot travel lane. The deck elevation ranges from 1107 feet on the dam side to 1102 feet on the intake tower side, with a normal pool elevation of 264.0 feet subject to reservoir level fluctuations.

The bridge has an inventory rating of 37.8 tons (HS-21) and an operating rating of 63.0 tons (HS-35), indicating the load-bearing capacity limitations for inspection equipment and vehicles that may access the structure. The document includes a photograph of the bridge showing its concrete construction spanning across the water between the dam infrastructure and the intake tower. This attachment serves as a detailed specification of one bridge location within the broader underbridge access equipment and services contract scope, providing inspectors and equipment vendors with critical structural and dimensional information necessary for planning safe access and inspection operations.
