Lock and Dam 52 is the 19th lock and dam on the Ohio River.[1] It is 939 miles downstream of Pittsburgh and 23 miles upstream from the confluence of the Mississippi with the Ohio.
The lock complex was completed in 1929.[1]
According to the New York Times, in 2015 80.2 million tonnes of cargo transitted the lock, making it the biggest and most economically important, in the United States.[1] In a profile of the lock the New York Times called the lock a "serious bottleneck", causing delays of 15 to 20 hours.
There are 2 locks for commercial barge traffic, one that is 1,200 feet long by 110 feet wide, the other is 600 feet long by 110 feet wide. Olmsted Lock and Dam is intended to replace lock and dam 52 and nearby lock and dam 53.[2] According to the New York Times, the Olmsted project was scheduled to have been completed in 1998.[1] In November 2016, the New York Times reported the Olmsted project was then scheduled to be complete in October 2018. The project's cost had ballooned from $775 million to $2.9 billion.
The New York Times reports that the US Army Engineers, the Federal agency responsible for maintaining navigation on the USA's rivers, the delay in replacing the lock complex with the Olmsted project costs $640 million per year.[1]
