Located in the foothills of the Appalachian Mountains, this 1,985-foot, five-span structure has the highest bridge span in the state of Virginia. Approximately 175 feet above the valley floor, it is composed of four double-tapered piers with stone inlay, two conventional abutments, and 100 cast-in-place segments. Working at this height over difficult ground terrain posed a significant challenge during construction. The box girder varies in depth from 31 feet at the piers to 12 feet at mid-span. The cast-in-place superstructure was constructed using the balanced cantilever method with form travelers, an accelerated bridge construction (ABC) method that minimized the environmental impact to the natural preserve below.
A part of this project was used by Virginia Polytechnic Institute in an effort to analyze and design “smart” transportation systems. With access to the bridge and testing of on-site pavement technologies, Virginia Tech was recognized as a research leader in Smart Transportation Systems.
