BURNS HARBOR, Ind. (AP) — The company that operates Indiana ports says the three ports handled a record 12.2 million tons of cargo in 2015.

It was the first year in the Ports of Indiana’s history that the state’s three ports handled more than 12 million tons.

The (Munster) Times reports the Port of Indiana-Mount Vernon near Evansville handled 6.6 million tons of cargo, while the Port of Indiana-Burns Harbor and the Port of Indiana-Jeffersonville across the Ohio River from Louisville, Kentucky, each handled 2.8 million tons of cargo.

The ports are doing so well Gov. Mike Pence has proposed building a fourth port in the southern part of the state. Gary and East Chicago also have expressed interest in another deepwater Lake Michigan port.
