Information from updated Georgia Historic Bridge Survey (GHBS):
The bridge carries a 2-lane state highway over the navigable Front River channel of the Savannah River at Port Wentworth. The bridge is on the Ocean Highway at the border of Georgia and South Carolina. SR 25 (Ocean Highway) was developed by the state highway department and the Coastal Highway District as a 155-mile long link in a chain of highways running the full length of the southern Atlantic seaboard. The route was completed by stages from north to south from 1922 to 1930, when the route had been concrete-surfaced for its entire length in Georgia. The bridge is part of a 6 bridge causeway over the Savannah River complex (051-0055-0, other bridges in SC jurisdiction) that was completed in 1922 and widened in 1954. Southwest of the bridge is a memorial plaque to the Coastal Highway. Southeast of the bridge is a boat launch and playground. The area to the north and west of the bridge is undeveloped wetlands.
Summary of Significance:
The 51 span bridge consists of a swing span bridge with thru truss superstructure and T beam approach spans. Originally constructed in 1922, the bridge had an 18'-wide roadway. In 1954 the bridge was widened by removal of the original swing span bridge and replacement with a new 12' wider structure built by the American Bridge Co. The T beam spans were retained but widened by T beam additions of 6' to each side. Original concrete balustrades were removed and replaced with standard concrete railings. The 1954 swing span bridge is technologically significant as 1 of only 2 identified swing span bridges (the other dates to 1940, 309-0016-0). It is a late example of the swing span technology, which reached its greatest period of popularity around 1900. The truss is rivet-connected with rolled steel sections.
