At an overall length of 2,975ft, the bridge consists of a total of seven (7) piers – five (5) located on land with two (2) piers constructed on the river's edge. Cofferdams were designed and utilized for the construction of the two piers on the river's edge. Upon completion, the main span at 760lf, became the longest continuous segmental span in the United States. The project utilized 30,000cy of concrete and over 8,000,000lb of reinforcing steel. Consistent with balanced cantilever construction, the project incorporated the use of two (2) sets of form travelers.
Foundations for the piers were provided with the installation of 36 – 72in diameter caissons with lengths up to 60ft. Value Engineering practices were utilized to modify the foundation designs for Abutment No. 2 to incorporate the use of driven pile in lieu of caissons at the river piers and also at Abutment No. 2 where piling was substituted for drilled shafts.
