A new U.S.-flagged Great Lakes bulk carrier has been delivered for the first time in more than 35 years.

In 2019, the Interlake Steamship Company awarded a contract to Fincantieri Bay Shipbuilding to build a new River-class, self-unloading bulk carrier.

It is believed to be the first ship for U.S. Great Lakes service built on the Great Lakes since 1983. The ship will transport raw materials to support manufacturing throughout the Great Lakes region.
