Excerpt:
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.
...A German immigrant, and graduate of the Royal Polytechnic School of Berlin, Roebling came to the United States in 1831. It was not until 1845 that he built his first suspension structure. From 1845 until his death in 1869, he designed five major suspension bridges. Two — the Cincinnati-Covington Bridge and the Brooklyn Bridge — are still standing.
