Well, I am glad that someone is advocating for it.

Robert: Its like you read my emails today, as I indeed referenced the Book Bridge to PennDOT and the importance of its preservation in light of these losses!

Nathan:

Hopefully, the Book Bridge is safe. As you say, the demolition of these two structures really does illustrate the need to get these bridges marketed successfully. I also feel the same way about abandoned bridges that are in danger of collapse - whether relocated or restored in place.

Robert: I immediately contacted PennDOT Cultural Resources when I learned of this, and this bridge was demolished without their knowledge either, which has led to a discussion of the need to try to market these bridges for reuse before such horrific actions are unleashed.

Its little brother also got bulldozed: http://historicbridges.org/bridges/browser/?bridgebrowser=pe...

This bridge had multiple unusual features. This is a significant loss.
