This is an extradosed bridge, which means some of the prestressing tendons have been replaced by shorter towers and cable-stays. It has a main span of 590 ft, side spans of 456 ft, and transition spans of 170 ft. The bridge is supported by two 143 ft tall towers and a pier on each side of the river (see Google Earth photo). The towers are a steel/ reinforced concrete composite structure that Buckland and Taylor seem to prefer. The bridge was completed in 2008.
