Description

The Port of Miami Tunnel improves access to and from the Port of Miami, serving as a dedicated roadway connector linking the Port (located on an island in Biscayne Bay) with the MacArthur Causeway (State Road A1A - which connects Miami to Miami Beach) and I-395 on the mainland. Previously the Port was linked to the mainland only by the Port Bridge. The tunnel: (i) improves access to the Port helping to keep it competitive and efficient, (ii) improves traffic safety in downtown Miami by removing cargo trucks and cruise line buses from congested city streets, and (iii) facilitates ongoing and future development plans in and around downtown Miami.
The project includes a tunnel under the Main Channel (the shipping channel between Dodge and Watson Islands), roadway work on Dodge Island and Watson Island/MacArthur Causeway and widening the MacArthur Causeway Bridge. Twin tubes, each 3,900 feet long and 41 feet in diameter, reach a depth of 120 feet below the water.

The project has been developed as a public-private partnership with Miami Access Tunnel, LLC (MAT). The state agreed to pay for approximately 50 percent of the capital costs (design and construction) and all operations and maintenance, while the remaining 50 percent of the capital costs is provided by the local governments.

Under the concession agreement, FDOT paid MAT a total of $100 million in milestone payments during the construction period between 2010 and 2013 and a $350 million final acceptance payment upon construction completion. This is followed by 30 years of availability payments during the operating period. The annual payment is $32.479 million (2009$), with adjustments for inflation. Deductions are made from this amount if MAT's operation of the facility does not meet prescribed performance standards.

Availability payments are pledged to secure the TIFIA loan.
