The main structure is 2,745-ft (837-m)-long with a main span of 1,222 ft (372 m) providing a navigation channel of 1,187 ft x 133 ft (362 m x 41 m). The bridge deck is 82-ft (25-m)-wide and carries four lanes of traffic with a full shoulder on each side. During several inspection campaigns, corrosion was discovered in the original stay cable system composed of parallel ¼” wires (up to 307 wires per cable).
IBT has developed a cable replacement strategy that minimizes impact to traffic and modifications to the existing structure. The stays will be replaced with a modern parallel strand system with superior durability and maintenance characteristics. Temporary cables will enable the bridge to remain in service throughout the procedure without the need for load restrictions.
