View An Excerpt of a Historical Article About A Previous Wooden Rockville Bridge

This amazing bridge was the longest stone arch bridge in the entire world when built and research appears to show that it remains the longest stone arch bridge in the world even today. As such, this bridge has national (and indeed global) significance as a bridge of record length, both when built and still today. It is also a significant monument to the might of the Pennsylvania Railroad, one of the most noteworthy railroad companies of its time. The bridge also retains excellent historic integrity with no major alteration aside from the addition of a plate girder at one end and repair of a spandrel wall with concrete toward the center of the bridge.

The stone arches are built with Clearfield County sandstone. The bridge has a concrete interior which was employed to reduce costs and increase construction speed.

Is is known that earlier bridges at this location, also undoubtedly among the longest of their kind, existing here. One was built in 1849 and was a wooden bridge following Theodor Burr's Burr Arch type. A number of Burr Arch bridges were built on the Susquehanna River. However, it is believed that the below unidentified photo may be the Rockville Bridge. This bridge was replaced in 1877 by a metal truss bridge, also shown below.
