Jim Drago and Bing Wu inspect the bottom of the concrete structure. The bridge was widened in 1972.

When a bridge fell in Washington last month it rekindled questions about the state of our nation's infrastructure.

That span over the Skagit river had been rated both "functionally obsolete" and "fracture critical" prior to collapse. Right now in California there are more than 600 bridges labeled either functionally obsolete, fracture critical or "structurally deficient," but experts say the labels are misleading.
