Turkey Knob Bridge
Posted July 29, 2008, by steven tygart (stygart [at] alltel [dot] net)

This bridge you call the Turkey Knob Bridge is a bridge that I have always know as the Orleans Bridge. Since it is at the site of the town of Orleans,Mo. which is know longer there. The only thing that is lift of Orleans is the school house at the top of the hill to the east of the bridge.
