The Port of Savannah soared into prominence in the container shipping business back in 1984, when Malcom McLean, then head of United States Lines, made the Georgia seaport, along with New York, one of the two “load centers” for his new “round the world” service operated with a dozen 4,246-TEU “Econships,” vessels designed with short smokestacks so they could slip beneath the old Talmadge Memorial Bridge, since replaced in 1991 by a new bridge with 185-foot air draft.
