Summary
Significance: The Scarlets Mill Bridge is a cast- and wrought-iron Pratt-type truss with a rolled upper chord arched in the form of an ellipse, one of many built in the 1870s and 1880s for the Philadelphia and Reading Railroad. It is unusual in its use of the elliptical form and in its late use of cast iron for principal structural members. It is one of only two of these "overhead bowstring bridges" known to survive.
