A Spider Barge (right) distributes outer-channel sediment into a barge held in place by a tug boat (left), as a Cutter Head Dredge Alaska (outside frame) pumps material through the pipe. The work is part of the Savannah Harbor Expansion Project. The outer channel will extend up to 20 miles into the Atlantic when complete, making the entire shipping channel 40 miles long from entry to Garden City Terminal.
