Specifications include, but are not limited to: HUGHES BRIDGE SB, located in Nicholas County, West Virginia. The structure carries US 19 southbound over Summersville Lake and is located approximately 0.22 mile north of CR 19/66. The bridge is a seven-span structure with two-span continuous beam approaches at either end, and a three-span deck truss for the main spans. The project shall consist of the design and preparation of contract plans and related documents for the rehabilitation of the existing structure. Rehabilitation shall include addressing the elevation differential in the bridge deck at the finger joints of the bridge, specifically the joint between Span Two and Span Three at Pier Two and the joint between Span Five and Span Six at Pier Five, in addition to replacing the existing bridge deck and rehabilitating the substructure units. The project shall consist of two phases. Phase I shall begin with an inspection of the bridge to become familiar with the finger joint problem, focusing on the finger joints at Pier Two and Pier Five, the overall deck, and the bearings of the truss and approach spans. The Consultant shall also investigate the cause of the misalignment as well as possible corrective actions. In addition, the Consultant shall perform any additional inspection efforts required to quantify deficiencies that need addressed in a substructure renovation. The Consultant is tasked with determining or proposing an explanation to the cause of the elevation difference between the approach spans and the truss spans. Multiple solutions to the problem shall be proposed with a general work plan and cost estimate for each option. After presentation of the solutions and discussion, the WVDOH shall select an option to address the finger joint problem as well as the basic approach for the deck replacement and the substructure rehabilitation. Phase II shall be the preparation of detailed construction contract plans for the rehabilitation of the bridge and shall be done as a planned supplemental agreement.
