Susquehanna River and Rockville Bridge, looking East. Marysville Pennsylvania


Opened in 1902 under the direction of Chief Engineer William H Brown, the Rockville Bridge is the longest masonry arch railroad viaduct in the world. Built by the Pennsylvania Railroad, the 3820' long span is made of 48 seventy foot spans over the Susquehanna River, connecting the PRR Harrisburg Terminal and Buffalo Line with the Mainline West, and connection to the sprawling Enola Yard complex through a complex junction in Marysville PA. This area of the PRR was the Eastern Hub of lines coming from New York, Philadelphia, Baltimore, Buffalo, and Hagerstown, creating a westward funnel, concentrating mainline traffic to Pittsburgh and points west.

While the terminal deserves more in depth coverage, the Rockville Bridge and supporting approaches particularly on the West Bank in Marysville, represent the forward thinking of PRR engineers in designing and managing traffic flow of passenger, thru freight and terminating/ originating freight without interference and delay.

Today this bridge faithfully serves the Norfolk Southern Corporation seeing heavy freight traffic and a round trip of daily Amtrak NYC-Pittsburgh service trains. While the track layout has been altered over the years, changing from the original 4 track system, to three, to the current two track layout, the bridge's appearance is still just as impressive as Griff Teller's "1949 Main Lines-Passenger and Freight" commissioned  for PRR advertising purposes. Located on the West side, in Marysville, is a personal favorite location, to view the traffic crossing the mile wide river. Like many, I never seem to get enough of this impressive structure, another historic piece of the Standard Railroad of the World!
