South Carolina has deepened the Charleston’s port to make sure it can take in any ship and remains one of the largest harbors on the East Coast. The channel leading to the Port of Charleston is now 52 feet deep, once again allowing the biggest ships in the world to make it in and out of the harbor. The new channel runs some 40 miles (64 kilometers) through the inner harbor and open ocean and is wide enough where one ship coming in can pass the other leaving the state. “Any time, any tide, any day. I’m not sure anyone else can say that,” South Carolina Gov. Henry McMaster said at a Monday ceremony marking the end of the 12-year project. The Charleston port has long been seen as the economic heart of South Carolina.
