Construction Method and Specifications

The viaduct was erected from the top down using the L43 launching girder from DEAL with a pile driver mounted to the front of the launching girder. Precast piles were driven to the proper depth by the pile driver. The launching girder would then place precast concrete pile caps onto the pile groups. With the leading pier erected, the L43 could then deliver the precast tub girders to their final position before launching to the next span.
