The most important transportation hub in the state is the port of Manzanillo, handling 91.3% of the shipping of the state and the immediate region. It also operates as an overflow port for the commercial and industrial zones of western Mexico, the Bajío area and the center of Mexico, but handles overflow from as far as Los Angeles. Most of the merchandise that passes through here is part of the trade between Mexico and Asia. The port infrastructure consists of two types of installations. One is artificial, located in the interior port of San Pedrito and the other located in the bay proper. The artificial structure is a tall dock with a length of 450 meters and 225 meters wide for a surface of 10,125m2. The Manzanillo port has a dock for cruise ships, and an average of 58 ships visit per year. Nearby are two large private marinas, one in Las Hadas and the other at Isla Navidad. The port area is not fully developed, with over 130 hectares reserved for expansion.
