Unnamed Creek Bridge
Posted October 19, 2008, by Bob Davis (bobdaviscfi [at] earthlink [dot] net)

Here's a couple of photos of this bridge on 155th Avenue over Rock Creek as identified on local topo maps. It is just downstream of Rock Bluffs on the southwest side of the Des Moines River above Ottumwa.
