From wear-and-tear to substantial repair: Pittsburgh District extends life of Hannibal Locks and Dam
A welder installs new circle plates on a removed miter gate aboard the Henry M. Shreve floating heavy crane at Hannibal Locks and Dam in Hannibal, Ohio, Sept. 13, 2024. The crane can lift up to 550 tons, and was used to allow the U.S. Army Corps of Engineers Pittsburgh District’s repair fleet to rebuild damaged steel and replace corroded material on the gates. The $16.6 million project involves removing and rebuilding four miter gates, replacing eight anchorages, and conducting full inspections and repairs for one of the busiest navigation facilities on the Ohio River.
