| Description | A design-build project consisting of ballasted, precast prestressed T-girders spanning transverse, precast reinforced concrete caps, supported on composite piles (24-inch steel pie piles protected by 36-inch concrete cylinder pile sleeves), this project replaced 2,298 feet of trestle-span approaches on existing alignment on each side of a single-leaf rolling bascule span. Trestle spans were replaced during weekly track outages of 4-day duration. The bridge was designed and constructed to AREMA standards and to meet NCDOT's highly-corrosive coastal environment criteria. All environmental documentation and permits, design, construction, and construction engineering and inspection were done by the design-build team. |
