I've always crossed the "closed" bridge without worrying about it; it didn't fall down while I was on it!
I'm glad it FINALLY got replaced. The "closure" of the bridge endangered countless hikers. I am relieved no one was seriously injured trying to cross the brook elsewhere, at high water, while the bridge was signed as "closed."
My understanding was indeed that it was bogged down in the design phase. There was a battle between the "natural materials" folks and the "build a bridge that will last" folks in a couple State agencies.
(Another constituency, the "tear out all the bridges to restore the wilderness" folks, apparently did not get traction here, thank heaven.)
Based on the description, it sounds like we built a bridge that will last. I think that's great, because the next replacement cycle will probably take even longer.
