A lot of us, including I, have worked on ways to save at least the Dakota Co. side of the bridge and to a certain degree the swing span. However after reading the news story, chances of that happening right now are slim. I'm inquiring more about the incident and will post the latest as it arrives.

Thanks for the news, though.

Per our local paper, part of this bridge collapsed last week due to a buckled beam. It was going to be preserved as part of a riverside park, but now it's going to be torn down as it's too unsafe to save.
