Key takeaways about the condition of US bridges and their role in the economy

==========

The collapse of a Baltimore bridge highlighted the importance of bridges in the US. Thousands of bridges in the US are in poor condition, with four-fifths having problems with their substructures or superstructures. Iowa has the greatest number of poor bridges, followed by Pennsylvania, Illinois, and Missouri. Bridge collapses due to ship or barge collisions are rare but have occurred in the past. Bad bridges can eventually collapse due to lack of maintenance and repair. When bridges close or collapse, there are financial consequences. Federal funding of $40 billion has been directed to bridge repairs, but it is still a fraction of the estimated $319 billion needed nationwide.
