Florida Avenue Lift Bridge Replacement

  • Overview

    Narrow. That was the word used to describe the marine opening of the bridge formerly crossing the Inner Harbor-Navigation Canal at Florida Avenue. This Strauss trunnion bascule bridge provided a meager 90-ft. opening – a tight fit for today’s hulking maritime traffic. But thanks to funding made possible by the Truman-Hobbs Act, The Port of New Orleans could progress with plans to replace the bridge. Their vision: a state-of-the-art vertical lift providing 300 feet of navigational clearance. To help realize the ambitious project, The Port of New Orleans turned to the movable bridge design experts at Modjeski and Masters.
    As active partners, we worked closely with The Port during conceptual design. We completed a feasibility study and evaluated alternative design solutions and related costs. Next, our experienced structural, electrical, and mechanical designers developed final plans for the preferred alternative: a 342-ft vertical lift bridge carrying one railroad track, two roadway lanes, and one sidewalk. We brought an added dimension to the project: on-site observation. In addition to providing construction support from the office, personally-invested Modjeski and Masters team members set up field residency for monitoring construction.
    Sporting a fresh coat of cobalt blue paint, the streamlined Florida Avenue Bridge was completed in 2005. But it didn’t take long for The Port’s new bridge to face adversity. In the wake of Hurricane Katrina, Modjeski and Masters was dispatched to perform an emergency evaluation. As a trusted firm, we guided The Port to successfully restore bridge operations. Being ready and responsive to our client’s needs – it’s our way of staying committed beyond completion.
