Investigations following the collapse of the bridge in Minneapolis will tell us how it occurred and whether anyone bears responsibility for the failure.
In Tennessee, it would be very difficult for a case to be brought the most obvious potential defendants. Our state and local governments have a damage cap that make it impossible to economically pursue claims after such a disaster. Our "architects, engineers and contractors immunity act" make it impossible for them to be held responsible more than four years (ok, four plus one years) after construction (absent a showing of fraud). Our products liability act gives manufacturers of any component parts a get-out-of-jail-free after ten years.
Of course, perhaps contractor(s) working on the bridge at the time may be found to have some fault and perhaps a private firm did an inspection and did not perform it carefully – the facts will trickle out over the next few days. But in Tennessee the ability of these potential defendants to assert fault against the potential defendants mentioned above and have that fault reduce the recovery of the plaintiff (the magic of several liability and allowing fault to be placed on immune non-parties) make these cases a challenge, too.
