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.

Professor Paul King is an expert on Roebling and teaches at CityTech in Brooklyn, near the base of the Brooklyn Bridge. 

This Saturday, August 31, at Noon, he will speak at the D&H Canal Interpretive Center in Summitville, NY, focusing on Roebling’s contributions to the D&H Canal through his suspension aqueducts and their significance in the history of the Catskills.

Professor King appeared on Radio Chatskill with Tim Bruno.
