What PennDot has not done is consider the opinion of someone that can and has restored historic bridges with similar faults.
PennDot needs to think out of the box.
PennDot is not accustomed with restoration.
As shown by an outside consultant brought in by DCS, the NY side support can be repaired. This will result in an opportunity to get on top of the bridge and install netting under bridge.
Then the historic can be restored.

Skinners Falls Bridge needs to be saved, not taken down.
