Washington Boulevard


Negley Run, like most of the streams in the City of Pittsburgh, is invisible to us today. The stream once connected Squirrel Hill to the Allegheny River, but today there is no collective memory of the stream and very few clues in our urban fabric. Change was unavoidable in Negley Run –located on a relatively flat area east of the city, the East End was farmed and later urbanized. The incoming waves of residents considered the water as a resource or a nuisance that had to be controlled and, beginning in the early 1800’s, the stream was systematically rerouted, straightened, channeled, and covered.


Capacity + Context

Washington Boulevard today is a speedway for cars and trucks with little visible evidence of the stream that used to flow in its place. Features such as Silver Lake were paved over in the early and mid twentieth century, and storm water was directed through drains underground into the combined sewer system. Heavy rain storms create dangerous conditions on the road, which have resulted in death for at least a handful of people over the years…
