standard gauge railroad tracks, with a total length of 52 feet (16 m).^[1]

Precursors

The first bridge at the site was built by the

Pratt truss in 1890.^[4] By around the start of the 20th century, however, the double-track bridge was proving to be a bottleneck in the quadruple-track main line on both sides, and plans were made for a bridge that would carry four tracks across the Brandywine Valley.^[5]

Construction and history

While the PRR had been using steel bridges since the 1880s,^[5] and was constructing others nearby at the time, such as the High Bridge at Downingtown,^[6] President A. J. Cassatt decided in favor of a stone bridge at this location and elsewhere. This reflected the influence of PRR Chief Engineer William H. Brown,^[5] who rebuilt many of the railroad's bridges in masonry during his tenure.^[7] While more expensive than steel, Brown felt that stone bridges were stronger and more durable,^[8] and less expensive to maintain in the long term.^[5]

Work on the bridge began in November 1902, locating it slightly to the south of the double-track bridge.^[5] The bridge was completed on 1 September 1904^[9] and the main line was realigned to cross it, abandoning the old bridge. The realignment reduced the curvature in the area and completed the PRR's four-track main line from Philadelphia to the Conestoga River bridge near Lancaster.^[1]
