The U.S. Army Corps of Engineers Vicksburg District’s Lindy C. Boggs Lock and Dam (Lock #1) on the Red River will undergo repair work on the cable connections on five of its eleven gates.
These repairs are necessary because of failed or failing connections due to the deterioration of the nuts and washers that secure the hoist cables.
Funding for the project was made available last fall. However, river conditions have only now become favorable to make the repairs. The work began July 6 and is expected to be completed in 60 days. During the past eight years, the six other the gates have been repaired.
Repair work will be done to gates 1, 3, 4, 6, and 8. Gate #3 failed in 2014 and Gate #8 failed in 2015. These gates could not be lifted out of the water. Due to concern about the condition of the other three gates, engineers advised the other three gates only be raised to an opening of 17 feet. They were raised to this height in order to relieve stress on the cable connections and prevent impact loading from water running over the top of them.
The lock and dam is located at Red River mile 43.8 and about 11 miles north of Marksville, Louisiana. The lock and dam system is part of the Monroe Navigation Project Office. It is the first lock and dam on the Red River and is part of the J. Bennett Johnston Waterway system.
The J. Bennett Johnston Waterway traverses over 225 miles from its confluence with the Atchafalaya River to Shreveport-Bossier, Louisiana. The waterway includes five locks and dams and five ports, which handle approximately 9 million tons of commodities per year and support over 1300 jobs.
The waterway offers convenient, cost-effective access to regional, national, and international markets. Commodities that have been the staple for the ports include refined oil products, fertilizer, construction grade sand & gravel and steel products.
