Six percent of Oregon’s bridges are considered structurally deficient. That’s according to a new study by Transportation 4 America.  Chris Rall with the group says the study is meant to draw attention to bridges that carry a fairly large amount of traffic and are structurally deficient; which means they will need some major repair or replacement in the near term. Rall says locally those include the Sellwood and Marquam bridges. But he says overall, Oregon ranks as 7th best in the nation when it comes to the state of its bridges thanks to a "Fix It First Policy."
