Seabrook Strauss Bascule Bridge Floor System Replacement and Bottom Chord RehabilitationThe Port of New Orleans' Seabrook Bridge is a double track Strauss heel trunnion bascule bridge, located in New Orleans, Louisiana. The project design and construction presented extraordinary challenges to engineers and contractors familiar with movable bridge construction. The circa 1923 bridge, due to severe deterioration of primary load carrying members necessitated the required repairs that included replacing the entire railroad floor system and truss bottom chords. The technical engineering aspects of the project had to meet the needs of the rail and marine interests by minimizing traffic interruptions and maintaining rail operations on the busy rail corridor.
