Norfolk Southern 4414 leads a freight train westbound across the Rockville Bridge over the Susquehanna River at Rockville, Pennsylvania on the NS Pittsburgh line as they head for Enola Yard at Enola, PA on November 5th, 2021.
According to Wikipedia: The Rockville Bridge is the longest stone masonry arch railroad viaduct ever built, with forty-eight 70-foot spans and a total length of 3,820 feet (1,160 m). 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. Completed in 1902 by the Pennsylvania Railroad, it remains in use today by the Norfolk Southern Railway and Amtrak’s Pennsylvanian route.
The bridge was listed on the National Register of Historic Places in 1975 and was designated as a National Historic Civil Engineering Landmark in 1979.
The first bridge at the site was a one-track wooden truss. It opened on September 1, 1849, when the PRR began operating over it. The Northern Central Railway began to use it after abandoning their Marysville Bridge. It was replaced in 1877 with a double-track iron truss bridge.
The third and current bridge was built between April 1900 and March 1902 by Drake & Stratton Co., which built the eastern half, and H.S. Kerbaugh, working from the west. The laborers were Italian or local.
Control of the bridge passed to Penn Central after the PRR merger in 1968, then to Conrail and finally the Norfolk Southern.
