Sir, couldn't agree more - however, Agnes was a once in 100 year storm. (for the central PA area) Lived through it. That would not be the real threat.
In this proposed timeline, the bridges would have went down in July. Back up soon after. The real yearly threat to any expediently re-build cross-river structure would have been the next year's spring thaw / flood. Huge broken pieces of ice flowing down river at speed and slamming into bridge supports have been the epitaph of more than one south central PA bridge.
For a long term solution, it would have to be re-built almost immediately out of sterner stuff, unless like the above pic - the stone casements were re-used as supports.
Cheers,
