Ledges State Park Des Moines River Bridge
Posted January 3, 2013, by Don Morrison

Fascinating.

Spent a lot of time in the area and on the river and never knew that this bridge ever existed. Looks like a pair of lally columns at 41.998616,-93.904142. Must've crossed from Moingona road to Camp Hantesa. Bird's Eye view turned to south gives a good view of the bridge remains and the road near the camp.

Cool find.
