 The general contractor Bouygues was fined $115,000 for every day that the tunnel was not open, losing millions of dollars.In March 2011, one of the sub contractors of Bouygues fell under criticism for the dumping of tunnel fill on sensitive wetlands on Virginia Key.They were supposed to be dumping the fill on Virginia Key on the degraded northwest side, but were found dumping it 80 to 100 yards (73.1 to 94.5 m) from the designated spot, where they damaged wetlands and killed about 40 mangrove trees with a piece of equipment that got stuck.
