Sidney Lanier Bridge

The Sidney Lanier Bridge replacement is a cable-stayed bridge with a main span of 1250-ft. and two side spans of 623-ft. each. The cable-stayed bridge is the longest spanning bridge in the state of Georgia and will allow larger ships to enter the port of Brunswick.

At the centerline of the navigational channel, the main span provides a clearance of 185-ft. The bridge has twin H-shaped concrete towers that rise to an elevation of 480-ft. with each tower anchoring cable stays in two planes. The concrete superstructure was constructed as cast-in-place segmental with form travelers.

The superstructure has a total width of 79.5-ft. and accommodates four 12-ft. traffic lanes and two 8-ft. shoulders. Each segment of the superstructure measures approximately 27.5-ft. in length, consisting of concrete edge girders with a depth of five feet. The bridge deck has a thickness of 11-in. with transverse floor beams at each edge girder stay anchorage location. Each of the towers supports the deck with 44 stay cables anchored to the concrete edge girders on either side of the bridge deck. This results in 88 stay cables per tower for a total of 176 stay cables supporting the concrete superstructure. Construction was completed in 2001.
