Truman-Hobbs: Quantifiying Navigational Benefit

The Truman-Hobbs Act of 1940 provides a process through which the U.S. Coast Guard decisively participates in waterways management. This process is used to identify, analyze, and recommend alterations to bridges that are unreasonable obstructions to navigation. These bridges often predate the modern waterway and impede or prevent realization of their full potential. When waterway improvement projects (such as channel widening, dredging, straightening, or replacing outdated locks and dams) have been completed, but antiquated obstructive bridges remain, the waterway's promise of improved efficiency is unfulfilled. This article describes the process and tools involved in administering, quantifying, and carrying out bridge alterations under the Truman-Hobbs Act since 1967. Results show that altered bridges immediately improve the efficiency of waterways and that allisions are greatly reduced, the navigation industry realizes a tangible navigational benefit, and that the threat of environmental harm is significantly reduced.
