Train track abutments that supported train crossing over Delaware River from NJ to PA

These structures date back to the early 1800's. My friend, Gary and I took a canoe trip around them in 2002. They are pretty massive. The one closest to the PA side, as you can see, is falling over. The tracks continued on right into the heart of Minisink Hills and along the Brodhead Creek across from the paper mill (now RockTenn) and connected to train tracks a little past the Interstate 80 overpass. These tracks are still in use today. I have always found these structures fascinating. The railroad that originally built these abutments was called the New York, Susquehanna & West Railroad. The first photo is where the trains tracks used to be. The land around the road is quite marshy on one side and must have been difficult to raise it up about ten to twelve feet to support the weight of trains.
