Tunkhannock Viaduct

Over this past weekend I went to Pennsylvania to visit my friend and watch the new Star Wars movie. It is sort of a tradition we have. With some time to kill on Saturday, he decided to drive me around and show me a couple of train bridges. One of them was the famous Tunkhannock Viaduct, which was built by the DL&W from 1912 to 1915. While the bridge is a fascinating study in old engineering techniques compared to today's bridge construction, it was just impossible to take it all in from the ground. It was too cold to go exploring, but some day with nicer weather I may venture down again and check out their visitor's center.

Some information about the bridge: it is 2,375 feet long and 240 feet high. When completed, it was the largest concrete structure in the world. It is still used by Norfolk Southern, though sadly we didn't see a train on it when we were there.
