I have walked and driven across this bridge every since I can remember. Love this old bridge as a part of everyday life in a small town. (Even if a flood happens)

This bridge is like a part of my life every single day. I drive over this bridge at least twice a day and have ever since I was born. You cross this bridge going into Imboden of course coming from Pocahontas I live on Highway 62 going towards Pocahontas. It would be hard to say how many times I've actually crossed it.
