Port Tunnel
Budget: $915 million
Scheduled Completion: Summer 2014

Scheduled for completion in Summer 2014, the Port Tunnel will improve access to and from PortMiami serving as a dedicated roadway connector linking Port facilities with Florida’s Interstate System. In addition to providing quicker access for Port-bound trucks and automobiles, the Port Tunnel is designed to reduce traffic congestion on downtown Miami streets.

The tunnel is comprised of two side-by-side tubes that will carry traffic underneath Biscayne Bay. The project includes roadway work on adjacent roads and the widening of the MacArthur Causeway Bridge that links downtown Miami to Miami Beach.

The public-private partnership project includes the following participants:

  • Florida Department of Transportation
  • Miami-Dade County
  • City of Miami
  • Miami Access Tunnel
  • Bouygues S.A.


Nearly 16,000 vehicles travel to and from PortMiami through downtown streets each weekday. Truck traffic makes up 28 percent of this travel. The tunnel will make downtown streets safer and reduce traffic. As part of PortMiami's sustainability initiative, the tunnel will reduce idle vehicle time as well as cut on vehicle emissions.
