Lock and Dam Equipment Mechanic Bill Wolford primes a trash pump for routine maintenance at New Cumberland Locks and Dam in Stratton, Ohio, April 14, 2023. New Cumberland is integral to Pittsburgh District’s mission to support safe and reliable navigation on the Ohio River year-round. It is also the third most-used lock of the 23 navigation locks and dams across the Pittsburgh District’s 328 miles of navigable waterways, moving more than 21.5 million tons of commodities along the river annually, totaling almost $4 billion in value. Shippers save nearly $550 million annually by moving commodities by river instead of truck or railway. (U.S. Army Corps of Engineers photo by Andrew Byrne)
