Good thing they evacuated it because Hurricane Sandy entirely flooded the Brooklyn Battery Tunnel. The MTA just released video taken during Governor Cuomo's tour of the tunnel this afternoon and holy crap the recently renamed Hugh L Carey Brooklyn Battery Tunnel is really, really flooded:

How eerie is that? Between this video and the one of the South Ferry and Whitehall subway station completely submerged, the MTA certainly is putting everything out there. Oh and by the way? According to the MTA there are about 43 million gallons of water in each of the tunnel's tubes.
