After four years of construction, including a delay from this past May, the PortMiami Tunnel has opened, giving trucks and other vehicles easier access to nearby highways.

The PortMiami Tunnel will improve access to and from the port, serving as a dedicated roadway connector linking the port with the MacArthur Causeway and I-395, according to facility management. The port is located on Dodge Island, a 518-acre island in Biscayne Bay.

The tunnel provides two dedicated lanes in each direction connecting the airport and interstate highway directly to and from PortMiami. Both cruise and cargo traffic are able to use the tunnel to access PortMiami.

The tunnel restrictions are a maximum height of 15 feet, a maximum width of 8 feet 6 inches, and no placarded and hazmat cargo are allowed in the tunnel. Restricted cargo will continue to use the Port Boulevard Bridge.

Prior to the tunnel being built, the only way into the port was through Port Boulevard. That caused heavy truck traffic, cruise line buses and private cars to congest the narrow central business district, in downtown Miami.

More information about the tunnel is on the PortMiami website.
