Waterways Council, Inc. released a study by HDR, Inc. (Recommendations for Improving the Delivery of Inland Waterway Capital Projects and accompanying infographic) that examines why costs for U.S. inland waterways capital projects (locks and dams) escalate, timelines for completion continue to slip, and economic benefits to the Nation from projectsā execution are consistently delayed. The U.S. Army Corps of Engineersā Civil Works mission is responsible for constructing the Nationās inland waterways infrastructure.
