It is a two-ribbed, open-spandrel, reinforced concrete arch bridge with one principal span. It was designed in 1927 by Paul Philippe Cret, a nationally acclaimed Philadelphia architect, in collaboration with Frank M. Masters, engineered by Ralph Modjeski and Clement E. Chase. It was completed in May 1932 at a cost of $1,648,775. It was designed to accommodate a lower deck, never constructed, to be used by trolleys or a subway extension to Roxborough.[2] Shortly after its completion, it was renamed the Wissahickon Memorial Bridge and was dedicated to the people of Philadelphia's northwest neighborhoods who served in World War I.

Henry Ave. Bridge

The bridge is 333 feet long, with a main span of 288 feet. Its 60-ft-wide roadway carries two lanes of traffic in each direction. The roadway is approximately 170 feet above the ground.[3] The bridge was repaved and repaired between 2008 and late 2010.

The bridge has been known as a suicide bridge since its opening. Beginning in 1941 for an unknown duration of time a policeman patrolled the span, questioning all pedestrians walking the bridge.[4]

It was listed on the National Register of Historic Places in 1988.
