More than a quarter of bridges in Pennsylvania are structurally deficient, giving the state the highest rate of unsound bridges in the country, according to Transportation for America. The number of structurally deficient bridges in the state will likely increase over the next several years as funding for bridge projects in the Pittsburgh region is expected to decrease, says the Pennsylvania Department of Transportation. "Nationally, things aren't much better; engineers are constantly doing triage to keep bridges open and safe," says ASCE's president-elect, Andrew Herrmann.
