Structural safety in doubt after Mall of America parking lot accident.
It's such a tragedy that someone got killed by going to the Mall of America with a U-Haul truck ("Mall of America ramp remains closed," Aug. 7). I see that the mall and local police are being very mum about how a small, unloaded truck could take down a major support beam. An independent panel of structural engineers should investigate, to determine how this could happen and what can be done to prevent it from happening again. If this ramp is built like some other buildings I've seen, the beams just sit on a step in the vertical post. Just a small bump, and the beam slips off the step, and the thing comes down.
