The dredge Padre Island of Great Lakes Doc & Dredge Company, works to deepen the outer channel of the Savannah harbor as part of the Savannah Harbor Expansion Project (SHEP) on March 30, 2016. The harbor deepening will allow larger, post-Panamax ships to visit Savannah more easily and with heavier loads. Savannah's Garden City terminal is the fourth busiest container port in the USA and the second busiest on the East Coast.
