General view of the Bloomfield Bridge, looking Southeast in Pittsburgh on July 21, 1914. Connecting Bigelow Boulevard and Liberty Avenue, the bridge took one year to build. It was designed by the city's Bureau of Bridges for an approximate cost of $450,000 but built by the Fort Pitt Bridge Works. The cantilevered structure totals 2,100 feet in length. The main span is 400 feet long of cantilever construction and consists of two cantilever arms, each 140 feet long, and one suspended span of 120 feet.

This view illustrates why the total and trusses lengths are different.

The Washington Crossing Bridge was finished in 1924. This 2,432' (741m) long bridge has a main span of 380' (116m). The 1991 rehabilitation retained "a relatively high level of historic integrity" [HistoricBridges] 

The vertical clearance is 180' (55m) at the center of the arches and 72.5' (22m) at the spring lines of the arches. [PGHbridges]

This was the 43rd Street Bridge in Pittsburgh, also known as the Ewalt Street Bridge. It was built in 1870 and connected Butler Plant Road in Millvale to 43rd Street (formerly Ewalt Street) in Lawrenceville. The bridge was demolished in 1924 and replaced with the Washington Crossing Bridge at 40th Street. The 43rd Street Bridge was the last covered bridge in Pittsburgh.

Dan Swartz: Knowing the location of the remaining retaining wall for this bridge and its height above normal pool I would say the river in this picture was at high flood level.

"Significance: The Washington Crossing Bridge is an outstanding example of a long-span metal deck arch bridge. Its unique architectural details, forged in a successful collaboration between architects and engineers in the design and construction of the bridge, add to its significance. The bridge is also significant because its construction was the culmination of a conflict over Allegheny River bridge heights between the U.S. War Department and local governments. The Washington Crossing Bridge was listed in the National Register of Historic Places in 1988." [HAER_data]
