Correct about bridge in background is Wabash bridge. The bridge in the foreground in front of Market Street bridge is the Milwaukee Rd's downtown Ottumwa branch. The bridge is over the mill race and not the main channel of the Des Moines River.
The bridge past the Market Street Bridge is the Wabash Railroad Bridge. That bridge is now used as a hike/bike trail connection to the southside of Ottumwa near the John Deere plant.
