SAPELO ISLAND, Ga. (WSAV) - The Georgia Department of Natural Resources (DNR) has announced that two new gangways have been installed at the Sapelo Island dock. The Myrick Marine Corporation of Savannah installed the gangways. One was installed on the mainland at the Meridian Ferry Dock and the other on the island at the Marsh Landing Dock. The new GatorDock aluminum gangways were engineered and produced by CMI Limited Co.. Overall, each of the gangways are 91 feet long, eight feet wide, and designed for a maximum live load of 260 persons, or 52,000 pounds. The new installations come after the Oct. 19 collapse of the previous gangway at Sapelo Island’s Marsh Landing Dock. The Meridian Ferry Dock gangway was replaced as a precautionary measure. Wiss, Janney, Elstner Associates, Inc., a firm of engineers, architects, and materials scientists specializing in the investigation, testing, and design of repairs for buildings, bridges, and other structures, is conducting an independent investigation into the collapse on behalf of the state Office of the Attorney General. DNR and the Georgia Bureau of Investigation (GBI) are also continuing investigations.
