An Iowa Department of Transportation worker checks out the supporting ironwork of the east/southbound Interstate 74 Bridge between Bettendorf and Moline. The span has a 66 "sufficiency rating" in the Iowa DOT's bridge analysis, while the older west/northbound structure has only a 43 rating. The lowest rated bridge structure in Scott County is the Lincoln Road I-74 overpass in Bettendorf with a 33 rating. The overpass was struck by a semi-trailer truck carrying a tall load nearly a year ago, and one lane of the overpass remains blockaded.
