Pittsburgh Pennsylvania   -  The Smithfield Street Bridge  1883  - Historic NRHP

The Smithfield Street Bridge is a lenticular truss bridge crossing the Monongahela River in Pittsburgh, Pennsylvania, USA.

The bridge was designed by Gustav Lindenthal, the engineer who later designed the Hell Gate Bridge in New York City. The Smithfield Street Bridge was built between 1881 and 1883, opening for traffic on March 19, 1883. It was widened in 1889 and widened again in 1911. The bridge has been designated a National Historic Civic Engineering Landmark, a National Historic Landmark, and has a Historic Landmark Plaque from the Pittsburgh History and Landmarks Foundation.
The Bridges of Pittsburgh play an important role in the city's transportation system. Without bridges, the Pittsburgh region would be a series of fragmented valleys, hillsides, river plains, and isolated communities.

A 2006 study determined that Pittsburgh has 446 bridges, and with its proximity to three major rivers and countless hills and ravines, Pittsburgh is known as "The City of Bridges". The city of Pittsburgh and Allegheny County are the largest owners of great bridges in the country, in proper proportion to their size, with the possible exception of the City of New York, which is built on an island and surrounded by large bodies of water.[citation needed]52

According to a 2011 study by Transportation for America, 1,194 bridges in the Pittsburgh area—or 30.4%—were deficient, the highest proportion in the nation. 172
