Tunkhannock Viaduct
Posted July 5, 2010, by Barry Lauver (bllauver [at] toad [dot] net)

If you have never visited this bridge, it is worth the trip. It is even bigger than you imagine. Its nearby cousin to the north is nearly as large. Also the nearby Starucca Viaduct is a beautiful bridge.

When I traveled in England I went to see Thomas Telford's Severn River Bridge at Ironbridge. I was not disappointed, nor was I disappointed with the Tunkhannock (sometimes called Nicholson) Viaduct.
