The Indiana Harbor and Ship Canal is an artificial waterway on the southwest shore of Lake Michigan, in East Chicago, Indiana which connects the Grand Calumet River to Lake Michigan. It consists of two branch canals, the 1.25 mile (2 km) Lake George Branch and the 2 mile (3 km) long Grand Calumet River Branch which join to form the main Indiana Harbor Canal. The Indiana Harbor Canal also functions as a harbor and runs 1.4 miles (2 km) before reaching the Indiana Harbor which connects to Lake Michigan. In 2002, Indiana Harbor was the 45th busiest harbor in the United States, handling almost 13,300,000 short tons (12,000,000 metric tons) of cargo. Foreign trade accounted for only 500,000 short tons (450,000 metric tons) of that. Indiana Harbor is not a state-managed harbor, and it is maintained by the Chicago District of the U.S.
