I am going to look at the Silver lining here. As frustrating as having these two bridges destroyed has been for everyone that uses them, I think it has been blessing that it has happened the way it did. Clearly these bridges were rotting out. If they had not been accidentally destroyed, they would still be in use (and unrepaired) and still rotting even more. Eventually these bridges would have reached the point where foot traffic would have brought them down, and that could have had tragic consequences. I suspect that all of the bridges in the trail system are in a similar condition and should all be inspected, repaired or replaced before some group of young children brings a bridge down and all end up falling 10 feet into icy water on top of broken bridge detritus.
