This stone masonry arch railroad viaduct was built by the Pennsylvania Railroad & consists of 48 arches, each spanning 70 feet. The original bridge at this site was a wooden single-track structure built in 1849. In 1877, it was replaced with an iron 2-track structure. Construction of the current stone structure began in 1900.
The Rockville Bridge is located about 5 miles N of Harrisburg, connecting Perry County (S of Marrysville) & Dauphin county (at Rockville). It is still in use today by Norfolk Southern & Amtrak.
The cost to build the entire Rockville bridge was $975,150 - but a repair made in 1997, after a spandrel wall failed on one of the piers, cost $1 million.
