 According to the "Miami Herald" the financing structure of the plan is notable for the amount of financial risk taken by the builders in return for the long term concession on the tunnel.Opposition to the project states that it is a waste of taxpayer money, and may become Miami's Big Dig, the nickname of a tunnel megaproject in Boston, which was a $4 billion project that ended up costing $22 billion in cost overruns.Many believe that the Port of Miami Tunnel Project will be likely to have similar cost overruns, even though the Secretary of the Florida Department of Transportation (FDOT) promised that the project would finish on time and without overruns.
