Bridges: 77,000 deficient, 750 have I-35W design

At Bridge Site, Search of River Moves Slowly - New York Times

... Dan Dorgan, a state bridge engineer for the Minnesota Department of Transportation, said a “deficient” designation did not mean a bridge needed to be immediately replaced; 77,000 bridges across the country, he said, have a similar designation...

Elsewhere I read that 750 bridges have the same design as our fallen I-35W bridge. I wonder what percentage of those are rated as deficient?

Maybe Google will start attaching design and deficiency rations to Google Earth/Maps. I bet that would be a good way to attract users.

This accident may end up costing billions ...

8/3/07 Update: I thought a bit more about how Google could accelerate the infrastructure review. A "route around risky bridge" option for Google Map directions would concentrate minds wonderfully. One can readily imagine icons for bridges with the I-35W design and risk designation. Did I say "billions"? Sorry, I meant tens to hundreds of billions ...

8/9/07 Update: My wife points out that as much as we may despise Pawlenty, it was the Ventura administration, albeit as part of a GOP initiative that returned a state budget surplus to the taxpayer rather than, say, use it to repair bridges. So Jesse Ventura deserves a chunk of the I-35W bridge for his desk.
