Notes
  • Significance: When completed in 1908, the bridge was the world's longest concrete arch bridge. Taking inspiration from a 1904 masonry arch bridge in Luxembourg, Webster, and Quimby's two-rib, open-spandrel design uses a minimum of reinforcing steel. The bridge crosses Wissahickon Creek in Fairmount Park.
