Re: Minneapolis bridge collapse
Inspections as early as in the 90's found problems with the bridge. Here's the core of the mess:
"....fatigue cracks and corrosion in the steel around the bridge's joints were found as early as 1991. Those problems were repaired. Starting in 1993, the bridge was inspected annually instead of every other year.
State bridge engineer Dan Dorgan said the bearings could not have been repaired without jacking up the entire deck of the bridge. Because the bearings were not sliding, inspectors concluded the corrosion was not a major issue.
After a study raised concern about cracks, the state was given two alternatives: Add steel plates to reinforce critical parts or conduct a thorough inspection of certain areas to see if there were additional cracks. They chose the inspection route, beginning that examination in May."
Everything else is history.
