America's first cast iron bridge bridge not only still stands at Brownsville, Pennsylvania, but continues to carry daily traffic. The 150-year-old Dunlap's Creek Bridge was constructed by John Snowden, the proprietor of Brownsville's Vulcan Iron and Machine Works, and John Herbertson, foreman in Snowden's machine shop. Its designers were engineers Captain Richard Delafield and George W. Cass. The history of Dunlap's Creek Bridge is retold in this article.
