BIG LIFT SIMPLIFIES JOB
It is described how with two 650-ton lifts, two movable leaves were installed in only a few hours in the construction of a bascule bridge over the busy Elizabeth River in Virginia. The leaves would have taken months to fabricate in-place. It is noted that the tolerances required on the tight-fitting steel-framed leaves would have made it difficult to piece together the two 220 x 78-ft structures in place, and converting the middle of the Elizabeth River into a construction site would have caused serious disruptions to naval and commercial traffic. Another challenging feature of the new bridge was the building of the deepwater cofferdams for its 100 x 50-ft main piers and 65 x 20-ft river piers. Details of the installation are briefly summarized.
