[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Realistically, it should not take more than a couple or few weeks to open shipping lane. NTSB needs to do their job. Then simply cut up the pieces in the shipping lane and haul out. T[b]he Navy could do this with ease[/b] [/quote]

Really?  There's an absolutely massive amount of twisted steel and concrete submerged in 50 feet of water.  They'll have to cut the debris into pieces under water, bring in giant cranes to lift them up and out, put them on boats and haul them somewhere (where?).  I think you're really underestimating how much work this will be.  [/quote]

Shaped charges would do the trick pretty quickly, no? They don't need to recover portions of the bridge intact since it is quite obvious why it collapsed.[/quote]

No, that won't work too well.  You'd end up with a bigger mess of tangled steel.  They will send in teams of underwater salvage divers to cut and lift pieces that will then be lifted from the surface of the water to a barge.  It will be a very difficult job .  Divers will be limited to 80 minutes without needing to go through decompression on the way up.  Obviously more time since they are all decompression certified.  They may be able to rig some sort of a saturation dive platform that will allow the divers to work without decompression for up to a month.  And remember, the guys who will be working down there will have terrible visibility and that will compound the problems.

Don't hold your breath.  It will be a long time to clean this out.[/quote]

Why decompression?  The amount of time under?  It’s only 50 feet deep. My knowledge of scuba diving is limited. [/quote]
