Blackfoot River Bridge

I dropped the ball with communicating about the blackfoot river bridge. I believe it may just be forgotten about. I don't know any specifics about it other than it was somehow made in Missoula Montana in 1907 and I would bet there aren't any others from that period still around. Just hate to see it get to the point where it has to be torn down. It is currently still in use.

Jim, I would start with contacting local and state preservation groups to try and drum up support. If the bridge was truly a local product, then it would be worthwhile to get some records about it's construction if they are available. And getting support from the local residents is helpful as well.

Is the bridge in imminent danger, or are you just wanting to garner support in an attempt to keep that from happening?

how do you find out how to get a bridge restored rather than torn down? who to contact.This bridge is a possible candidate as it is one of the few left that was made in Missoula Montana.
