East Pittsburgh is a
borough in
Allegheny County,
Pennsylvania, about southeast of the confluence of the
Monongahela and the
Allegheny rivers at
Pittsburgh. The population in 1900 stood at 2,883, and in 1910, at 5,615. As of the
2010 census, the borough population was 1,822, having fallen from 6,079 in 1940.
George Westinghouse erected large works there which supplied equipment to the great power plants at
Niagara Falls and for the elevated and rapid-transit systems of
New York. Nearby, the
George Westinghouse Bridge over
Turtle Creek is a prominent fixture in the area, which is very near the borough of
Braddock.
