Pennsylvania & New Jersey Railroad, Delaware River Bridge, Spanning Delaware River, south of Betsy Ross Bridge (State Route 90), Philadelphia, Philadelphia County, PA

Significance: Because of its location on the lower Delaware River, the bridge has a collection of extremely long and heavy spans. These include the world's heaviest center-bearing swing span, completed in 1896, and longest double-track vertical-lift span, added in 1959. Both movable spans are still present, which is an unusual occurrence. The bridge is also significant as the first Delaware River crossing at Philadelphia, supplanting a ferry crossing for passengers and freight bound for southern New Jersey.
