Thanks to Lance Myers himself, this has been cleared up, the original photo I had used was indeed Stone Creek II but the bridge and it's info are from the smaller one known as Isenberg-Crossing or Stone Creek I. So to clear up all the confusion this is Isenberg aka Stone Creek Bridge on the old Right of Way on the future Rail to Trail along the Juanata.
This bridge is getting confused with Stone Creek Bridge II http://bridgehunter.com/pa/huntingdon/bh52643/
I do think this photo is NOT for the Isenberg Bridge which is located at 40.565266,-78.064224 but for Stone Creek Bridge II.
The photograph above is the old PRR bridge over Standing Stone Creek in the Borough of Huntingdon, PA. It was built
between the Summer of 1848 and Spring of 1850. The abandoned bridge was never used for pedestrian traffic.
Sadly no, I couldn't find much about this bridge aside the name and local history. I know that it was part of a rail-line and was nearly destroyed in the biggest flood of the 1940's but that's really about it.
Do you have a construction date for this bridge or other stone arch bridges in this area?
