The Rockville Bridge, at the time of its completion in 1902, was, and remains, the longest stone masonry arch railroad viaduct in the world. Constructed between April 1900 and April 1902 by the railroad, it has forty-eight 70-foot spans, for a total length of 3,820 feet. The bridge crosses the Susquehanna River about 5 miles north of Harrisburg, Pennsylvania. The eastern end is in Rockville and the western end is just south of Marysville.
The original bridge on the spot opened on September 1, 1849, when the railroad began operating over it. The current bridge was built by Italian laborers, who worked for two contractors, one on the east side of the Susquehanna River and one on the west. Local people from the Harrisburg area also worked on the bridge. For most of its life the bridge carried 4 main line tracks. In the late 1990s an intermodal container was blown off a freight train and landed in the river, prompting the railroad to reconfigure the track layout. This reduced the number of main line tracks to two, but left a buffer zone on either side to prevent further containers ending up in the river, although high winds from the departing December 2010 North American blizzard resulted in a similar outcome on December 27, 2010. The bridge was listed on the National Register of Historic Places in 1975.
