The Roebling Bridge in Lackawaxen, Pennsylvania, was designed and constructed by John A. Roebling as an aqueduct for D&H Canal Boats to cross the Delaware River. Mr. Roebling was the initial designer of the Brooklyn Bridge, NYC, the oldest suspension bridge in the U.S.
A more complete story of the building of the Brooklyn Bridge is found on the first link. All the links have been posts on the HalfwayBrook site and I hope are of interest to my readers. The Roebling Aqueduct/Bridge is just one of the stories I found fascinating as I researched the Halfway Brook Books.
