A 220-ft-by-10-ft Liberty panel bridge was recently used as a platform during the rehabilitation of a historic truss bridge in Ohio. The Liberty bridge, equipped with rollers on the overhead chord, was placed inside the existing historic truss and then elevated to the underside of the portals. After the bridge shoes were cut, the bridge was raised slightly and the existing truss bridge was rolled to a staging area, where it was dismantled. By using the Liberty bridge, the crew was able to avoid entering the waterway, thus eliminating the need for permitting and providing for increased control for the deconstruction. The process will be reversed when the rehabilitated bridge is reconstructed.
