[1COUNTER-MORTER-68]

Great pic,,,that tells alot,,,that’s an old bridge,,,
1967....Hey that’s not old.
~~~~~~~~~~~~~~~~
From what I can tell from the pics it’s old enough to have been put together with rivets,,,my guess is the iron was being replaced and put back together with bolts,,,
I’m gunna bet “Non-union” Iron workers,,,there was a thread about this awhile back,,,
