The $667 million PortMiami Tunnel (POMT) project was built by MAT Concessionaire, LLC, in partnership with the Florida Department of Transportation (FDOT), Miami-Dade County and the City of Miami.
By connecting SR A1A/MacArthur Causeway to Dodge Island, the project provides direct access between the seaport and highways I-395 and I-95, create another entry to PortMiami in addition to the Port Bridge to keep PortMiami, the community’s second largest economic generator, competitive.
Additionally, The POMT improves traffic flow in downtown Miami by reducing the number of cargo trucks and cruise related vehicles on congested downtown streets, and aids ongoing and future development in and around downtown Miami.

The project consisted of three components:
- Twin tunnels under Government Cut
- Connections to PortMiami’s roadway system
- MacArthur Causeway Bridge widening, realignment of eastbound State Road A1A/MacArthur Causeway lanes and reconstruction of Parrot Jungle Trail frontage road
