Navigation Span Location Study for Greenville Bridge Reach, Mississippi River
Abstract
Navigation conditions through the Greenville Bridge are difficult and hazardous, particularly with the channel shifting from the right to the left side, upstream of Island 84. Conditions at the bridge are affected by the limited straight approach distance and the velocity and alignment of the currents upstream of the bridge. In March 1948, the towboat Natchez hit one of the bridge piers and capsized with considerable loss of life. This tragedy focused attention on these navigation problems and intensified efforts to develop remedial measures. Several plans were proposed to improve navigation conditions at the bridge. However, because of the many factors involved in the development of the reach and the complex nature of alluvial streams, analytical evaluation of the proposed plans' effects are extremely difficult and inconclusive. Therefore, physical hydraulic model studies were necessary to measure the proposed plans' effect on stability, maintenance, and navigation in the reach.
