Its a nice looking bridge that follows a standard plan for girder bridges in Iowa. However, under the 10 point Historic Significance Rating I use over at HistoricBridges.org, the highest value I would assign this bridge would be Six Points in Local Significance and Five Points in National Significance. I gave a similar bridge I visited a 4-6 National-Local rating.
