This was built between April 1900 and March 1902 by the Pennsylvania Railroad and has forty-eight 70-ft spans, for a total length of 3,820 feet (1.164 km). It was was the longest such bridge in the world at the time, and that remains the case. It is 52 feet (15.9 metres) wide and 43 ft (13.1 metres) high.

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.  It is now on the Norfolk Southern system.
