The Allegheny River Lock and Dam No. 2 (also known as the Highland Park Lock and Dam) in Pittsburgh, Pennsylvania is a lock and fixed-crest dam from 1932. It crosses the Allegheny River between the Pittsburgh neighborhood of Highland Park and the suburb of Aspinwall. The lock and dam were built by the U.S. Army Corps of Engineers as a part of an extensive system of locks and dams to improve navigation along the Allegheny River. It is the most-used lock operated by the United States Army Corps of Engineers. Read more on Wikipedia
