Description 

The Christiana Borough Bridge is a rare survivor of the Whipple truss bridge structure with wrought iron Phoenix columns. Built in 1893-95 by the Pennsylvania Railroad during a period of railroad expansion, it replaced a timber pony truss bridge. As originally designed, the truss was intended to carry heavy railway loads. In this instance, however, because the bridge was built to carry highway traffic over the railroad, the design was modified to carry a lighter load.

-- Historic American Engineering Record

The cast portal bracing pattern was normally used prior to 1888. This bridge was likely originally built in the early 1880s and was repurposed and relocated as a grade separation project in 1893-1895. It's original build location is presently unknown -- Art S.
