The Vicksburg Protection works consists of a combination of a concrete floodwall, and an earthen embankment section, located on the east bank of the Yazoo Diversion Canal along the waterfront of the City of Vicksburg, MS. Total length of floodwall is 1.7 miles and total length of levee embankment is .2 miles. The Vicksburg Floodwall is a feature of the comprehensive flood control project of the Lower Mississippi River, authorized by the Flood Control Act of 15 May 28, as amended. The floodwall is a continuous, reinforced concrete wall, consisting of two types of monolithic construction: an I-type wall and T-type or cantilever wall. It was constructed in three reaches, consisting of a main reach, a north extension, and a south extension. Construction on the three reaches began in Jun 52 and was completed in Jan 59. The main reach consists of an I-type wall and a T-type wall. The I-type wall was constructed riverward of the old wall and the space between the two walls filled with sand. The T-type wall replaced the old wall entirely. The north extension contains a 90-degree angle, traverses several railroad tracks and a street to reach a natural hill. The south extension consists of I-type monolithic construction in conjunction with a levee that was part of the old protection system and a short T-type or cantilever monolithic wall section. This new floodwall raises the protection from the elevation of the old floodwall and levee (106.0) to the design elevation of 112.0. The 1973 project design flowline is 111.0 feet. The main reach and the north extension have copper waterstops across the joints and the south extension has rubber waterstops. There are 10 drainage structures that control flows through the wall system. Closure of the remainder of the openings is made by timber stoplogs when needed.
