Minneapolis Bridge Scored 50 Out of 120 in Inspection
White House spokesman Tony Snow said the Interstate 35 bridge that collapsed in Minneapolis on Wednesday had scored 50 on a scale of 120 in a 2005 inspection, which means it was rated as "structurally deficient." But The Swamp notes that Snow added that this did not mean there was a risk of failure -- or that "the national system of inspecting bridges will be reevaluated."
Transportation Secretary Mary Peters agreed, saying that the ratings didn't mean there was any danger.
"What that rating of 50 means is that the bridge should be repaired, should perhaps be considered for replacement at some point in the future," Peters said. "It was by no means determined that this bridge was not safe. Had that been the case ... Gov. Pawlenty would have shut this bridge down immediately.
OK, let me get this straight. Scoring 50 out of 120 does not mean there was a risk of failure? In almost everything else I can think of, scoring 50 out of 100 (let alone 120) doesn't mean there is a risk of failure -- it means failure. In fact, Thomas Rooney, a civil engineer interviewed on Day to Day, said he wasn't exactly sure what the problems were, but he believed the score meant the bridge should not have been in use. As he said, 50 out of 120 would not mean a pass even in a fifth-grade elementary class.
Even if bridges have an evaluation system that's different from school test scores, it would seem to me that the inspection would raise a flag somewhere in some state or federal department. Officials say that as many as 80,000 bridges in the U.S. share a similar score -- no doubt in an effort to show that getting such a score is not such a big deal.
I'm not so sure people who now have to drive over these bridges feel the same way.
