The old iron truss bridge at Whitford, Pennsylvania spans the existing Amtrak/Septa line into Philadelphia. The bridge was built in 1904-05 by Pennsylvania Steel Co. (Steelton, PA) to a design by H. R. Leonard.
At 373' -1" long this is an exceptionally long example of a "pin-connected Parker through truss" construction, exceeding the commonly accepted practical limit of 300'-0" for Parker-Type bridges.
The Whitford Freight Bridge was part of the late 19th century line modernization which separated freight traffic from passenger trains. It has been out of service since about 1990.
