The Port of Jacksonville is an international trade seaport on the St. Johns River in Jacksonville, Florida. The newest port in the United States, it carries over 21 million tons of cargo each year and is the second largest handler of vehicles in the United States with 656,805 in fiscal year. Morrison Knudsen answered yet another call to serve it’s country when the company worked hand in hand with The U.S. Army Corps of Engineers to perform the harbor dredging in 1952, 1978 and 2003. The company also combined forces with the United States Navy to bring the first Naval presence to Jacksonville shortly before World War II when we constructed two facilities. Today, the Naval Station Mayport, Naval Air Station Jacksonville, Blount Island Command (Marines) and nearby Naval Submarine Base Kings Bay form the third largest military presence in the United State where the Company continues to work in keeping the facility a state of the art harbor and base.
