The American Great Lakes Ports Association (AGLPA), including members Ports of Indiana, the Illinois International Port District (IIPD), and Port Milwaukee, in partnership with the Great Lakes St. Lawrence Seaway Development Corporation (GLS), announced a comprehensive market analysis aimed at expanding cargo movement between the Great Lakes and Inland Waterways system.
This study aims to leverage the river–lake connection to increase waterborne commerce, supporting critical American industries such as steelmaking, agriculture, energy, manufacturing, and other cargo. The current cargo shipment between the two systems is substantial, with close to 700 million tons of goods moved annually.
However, only a small percentage of this cargo currently moves between the Great Lakes and inland rivers. The study will examine opportunities to increase waterborne commerce by evaluating market demand, identifying promising cargo flows, and exploring the infrastructure and operational needs required to support greater integration.
By improving the flow of goods, especially exports that power the Heartland, the region can boost economic growth today and reinforce its nation's long-term competitiveness for generations to come. The study will also assess how expanded maritime service could improve supply chain reliability, support key industries, create jobs, and relieve pressure on congested highway corridors.
The partnership between AGLPA, GLS, and member ports aims to strengthen maritime commerce and reinforce the region's vital role in the nation's supply chains.
