The Port of Miami Tunnel
The Port of Miami Tunnel improves access to and from the Port, serving as a dedicated roadway connector linking the Port with the MacArthur Causeway (State Road A1A) and I-395. The Tunnel is open to everyone – both cruise and cargo traffic.
Nearly 16,000 vehicles travel to and from PortMiami through downtown streets each weekday. Truck traffic makes up 28 percent of this travel. In addition to providing quicker access for Port-bound trucks and automobiles, the Port Tunnel is designed to improve traffic flow in Downtown Miami.
As part of PortMiami's sustainability initiative, the tunnel reduces idle vehicle time as well as cut on vehicle emissions.
