Upper Delaware Scenic and Recreational River is the home of the oldest existing wire suspension bridge in the United States - the Delaware Aqueduct, or Roebling Bridge as it is now known. Begun in 1847 as one of four suspension aqueducts on the Delaware and Hudson Canal, it was designed by and built under the supervision of John A. Roebling, future engineer of the Brooklyn Bridge.
Portions of the D & H Canal, including the Delaware Aqueduct, were designated a National Historic Landmark in 1968. The Delaware Aqueduct is also designated a National Civil Engineering Landmark. The Delaware Aqueduct continued to function as a vehicular bridge until 1979. In 1980, the National Park Service purchased the aqueduct to be preserved as part of Upper Delaware Scenic and Recreational River. Almost all of the Delaware Aqueduct's existing ironwork — cables, saddles, and suspenders — are the same materials installed when the structure was built. Today, you may walk across the former aqueduct, following the path taken by canalers and their mules over a century ago. Where canal boats once slowly floated, modern vehicles now cross the Delaware River effortlessly.
