This bridge is actually on 110th Street, just off of Hwy 169 south of Algona, and the bridge has been closed to traffic. Just drove past it on the way to a track meet in Algona yesterday and it was definitely closed. Not sure if it's still open to pedestrian traffic, though.
This bridge is no longer here. I went back to take a winter photo after our last snowfall and to my suprise it was gone! I was just there this last October so I have no idea when they tore it out.
