Title: RESEARCH PAYS OFF: NAVIGATION MODEL STUDY IMPROVES RIVER SAFETY OF NEW BRIDGE
Accession Number: 00750084
Record Type: Component
Availability: Find a library where document is available Abstract: The U.S. 82 Greenville Bridge reach has one of the highest accident rates on the Mississippi River system. In 1995, the Mississippi Department of Transportation (MDOT) began designing a replacement for the Greenville Bridge. This article describes how use of the U.S. Army Corps of Engineers Waterways Experiment Station (WES) Greenville Bridge Reach Model enabled design changes to be made in the initial stages of the project. The cost of making these changes to obtain a safer design could have been significant had the information not been available until later in the design process. Use of the WES Greenville Bridge Reach Model demonstrated that the new bridge will provide improved navigational and structural safety for several reasons. First the relocation of the navigation span will greatly reduce the potential for the piers to be struck by a large Mississippi River tow. Second, the piers will be designed to withstand the potential impact of tows of a size known to move through this river reach. Finally, the pier caisson will be designed to accommodate the proper amount of riverbed scour.
