What would be the difference between this bridge and the past bridges that have fallen into a body of water? How about a torpedoed US Navy ship in some 3rd world country in a 13 foot tidal change in zero visibilty water? Scenarios?? May sound out of this world, but Navy and Commercial divers are trained to dive in theses conditions.

This is not the first bridge that has collapsed into the water. They lost a bridge in the Keys a couple of years ago, one in the Tampa area too. So this is not the first time divers have had to dive in these conditions. That is the reason they are using Navy divers, because they are trained to do this kind of stuff.

For the ROV, the technology has probably changed and my ignorance of new techonlogy shows. In the end they are still going to need divers in the water to attach cables that they are going to use to lift all the debris.
