Arizona ties Minnesota for last in bridge spending

Are bridges full of rush hour motorists going to collapse in Arizona as happened in Minnesota last year, killing 13 people and injuring more than 100? A new report prepared for the U.S. House Transportation Committee, chaired by Minnesota Democrat Jim Oberstar, ties Arizona for dead last with Minnesota in the amount of federal bridge money we spend. Of course, Arizona probably has far fewer rivers, and as for upkeep, so many of our freeway overpasses are much newer than in most states. Still, it's been a good 15 years since many of our Valley freeways and their interchanges were built. That seems like a good time to check in on how structurally sound they are and what maintenance they may need.
