The Allegheny River Lock and Dam No. 2 is a lock and dam at 7451 Lockway W in Pittsburgh, Allegheny County, built from 1932 to 1934 in the Late Nineteenth and Early Twentieth Century Revival style by Vang Construction Company.
Why it's listed
It was listed in the National Register in 2000 under criteria A and C, with a criteria consideration of G and state level significance in transportation, maritime history and engineering. Its period of significance runs from 1903, when construction began on the earlier Lock 2, to 1948.
Physical character
The lock and dam are built of concrete, and the operations building has concrete foundations and walls, a rubber-covered gambrel roof with flared eaves, a complex cornice, faux quoins and ornamental brickwork. The dam is fixed-crest, and the lock has steel miter gates on a concrete miter sill, reinforced concrete land and river walls, a concrete-paved esplanade, mooring pins and an overhead crane.
Historical context
An earlier Lock 2 was proposed in 1892 and built starting in 1903, opening in 1906 and completed with locktenders' houses by 1908; the present lock and dam replaced it, built from 1932 to 1934, beginning operation and seeing the old lock demolished that year.
