Either that or they decided to postcard a flood for whatever reason.

Somebody in the postcard world apparently let their imagination run away with them....

Yes Tunkhannock Viaduct is in Nicholson PA. There is an active Factoryville Tunnel on the NS line and here's a link to the abandoned tunnels http://www.undergroundminers.com/factoryvilletunnel.html

I was on an abandoned rail site and the Nicholson Viaduct was mentioned.Is this the Nicholson Viaduct?

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.
