Construction of one of the largest moveable bridges in the world was made possible only by advances in welding technology and the availability of waterway transportation to the construction site, which allowed the structural steel to be fabricated into the largest sections possible that could be shipped by barge. Because the box girders could only be adjusted at the single connection between the river and anchor arms, special fabrication and construction tolerances were specified. To achieve these tolerances during fabrication, cutting of the large and curving plates was controlled by computer.
