Huntington Avenue Bridge Superstructure Replacement, Newport News, VA
AMT designed the bridge superstructure replacement and abutment modification of an existing steel beam structure with masonry abutments. The 57’-long steel plate girder single-span structure and 80’-wide, rail to rail bridge carries four 10’-wide through traffic lanes, and a 17’-0” sidewalk on each side. The deck has a VDOT “open” BR27 steel railing on each side and a pedestrian fence to prevent debris from falling onto the Shipyard property.
The structure spans two rail lines for Huntington Ingalls Industries and carries a water line and two fiber optic conduit duct banks. All utility lines are accommodated under the bridge and through steel diaphragm, without interfering with the vertical clearance over the tracks. The most expeditious construction practice for this bridge was a complete closure and subsequent detour through the City of Newport News. The detour required careful consideration of the Newport News Shipyard and their daily schedule.
