Illinois state transportation officials are reviewing all highway bridges scheduled to be built or re-constructed. They want to make sure the bridges can handle the extra weight of construction materials. This scrutiny follows a federal report released Monday. It says a design error involving support plates led to the deadly collapse of a Minneapolis bridge last summer.
Federal officials also blame construction materials that added about 300 tons to the bridge the day it collapsed.
The Illinois Department of Transportation has inspected Illinois' 31 deck-truss bridges with those kind of support plates. Inspectors say they found no reason to worry.
