The Minneapolis I-35W bridge that collapsed in 2007 supposedly had bad gussets. Yet it had barely passed previous inspections; in 2005 it was deemed to have met "minimum tolerable limits to be left in place as it is".
In 2005 the US said it was in the same condition as 75,000 other bridges in the US: 'structurally deficient', which is also what the US called it in 1990. I'd guess that the same quality of decisions brought down Arecibo. Gotta pay the piper.
