The Rockville Bridge, at the time of its completion in 1902, was the longest stone masonry arch railroad viaduct in the world.[1] Constructed between 1900 - 1902 by the Pennsylvania Railroad, it has forty-eight 70-foot spans, for a total length of 3,820 feet (1,164 m).[1]

The bridge crosses the Susquehanna River about 5 miles (8 km) 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 PRR began operating over it. The Northern Central Railway built the Marysville Bridge to the north in 1858, and later moved to the expanded Rockville Bridge. The current bridge was built by Italian laborers, who were working for two contractors (Drake & Stratton), one on the east side of the Susquehanna River and one on the west.[2] For most of its life the bridge carried 4 main line tracks, but which was reduced to three in the 1980's when the PRR Main Line was modernized across Pennsylvania. In the late 1990's a shipping container was blown off an intermodal freight train and landed in the river prompting Norfolk Southern to reconfigure the track layout, terminating the wye track to Enola at the west end of the bridge. 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. Currently, the bridge is used by the Norfolk Southern and Amtrak. The bridge was listed on the National Register of Historic Places in 1975.[3]

On July 2,1986 a 25 ft (7.6 m) tall replica of The Staute of Liberty was erected on one of its piers in the Dauphin Narrows of Susquehanna River. The replica was built by a local activist Gene Stilp. It was made of venetian blinds and stood 18 feet (5.5 m) tall. Six years later, after it was destroyed in a windstorm, it was rebuilt by Stilp and other local citizens, of wood, metal, glass and fiberglass, to a height of 25 feet.
