The U.S. inland waterways system provides a highly efficient means for moving large quantities of bulk materials – agricultural products and natural resources – which is important both for domestic industries and the export market. But the locks and dams that support the waterway network comprise an aging infrastructure with limited capacity and almost no redundancy. Planned and unexpected lock closure for maintenance and rehabilitation impose substantial costs on our economy. In this podcast we discuss the condition, performance, and funding of the inland waterways system with Dr. Craig Philip, who is Research Professor at Vanderbilt University and Director of VECTOR, the Vanderbilt Center for Transportation and Operational Resilience. Before joining Vanderbilt, Dr. Philip spent 30 years in the barge industry, 14 as President and CEO of Ingram Barge Lines, now the largest domestic maritime operator in the United States
