Pam Key alerted me on the Old Iron Bridge in Nevada County. Nachitoch Bluff Crossing on Little Missouri River 6 miles North of Prescott. The bridge was built in 1908. Through the 1970s, this was a favorite picnic spot and swimming hole.
Now there is a major move to restore it. Check out and join their facebook page to show your support! The Bridge Hunter also provides more photographs and more information.
