Alex Benedict, a project engineer with the U.S. Army Corps of Engineers Pittsburgh District, supervises a construction project at Montgomery Locks and Dam, in Monaca, Pennsylvania, Oct. 25, 2023. The Montgomery Lock and Dam megaproject will demolish and expand the 87-year-old auxiliary chamber at the facility during the next 10 years to accommodate more barges navigating on the Ohio River. The current phase of construction involves clearing an area to construct a batch plant. The batch plant will produce about 500,000 pounds of concrete to reconstruct the middle wall and river wall during the expansion.
