Officials in Miami-Dade County are exploring the possibility of establishing a direct train service connecting the Miami International Airport and PortMiami. These two key facilities are in pursuit of expansion and modernization but currently lack a swift and direct public transportation link.
This initiative stems from a feasibility study released in September 2025 by the Miami-Dade Transportation Planning Organization (TPO), with funding support from both the U.S. Department of Transportation and the county itself.
The proposed project aims to offer a non-stop rail service enabling travelers to move between the airport and port in under 30 minutes, bypassing the traffic congestion typical on busy embarkation days.
Exploring Feasible Options
The study considers two technically viable alternatives. The first is an extension of the Metrorail spanning approximately 10 miles, with a projected capital cost ranging from $700 to $800 million and operational expenses of $12 to $15 million annually. This option would provide greater passenger capacity and a more direct route.
The second option is an automated people mover system, akin to the MetroMover, covering about nine miles. It is estimated to cost between $600 and $700 million, with operational costs between $9 and $11 million per year. While its capacity is limited to about 50 passengers per car, its implementation would be swifter.
Both alternatives include a new 1.9-mile elevated section from the Overtown area to PortMiami, crossing the intracoastal waterway via a newly constructed bridge.
Projected Demand and Current Challenges
Usage projections estimate between 1.1 and 2.1 million passengers annually by 2050, according to the TPO study.
The demand is pressing and increasing: PortMiami concluded the fiscal year 2025 with a record of 8.56 million cruise passengers, marking a 4.02% year-over-year growth. Its Master Plan 2050 anticipates reaching 24 million passengers.
Meanwhile, the airport handled nearly 56 million passengers in 2024 and is projected to accommodate 77 million by 2040. It ranks as the second busiest in the U.S. for international passengers and the top for international cargo.
Currently, the only public connection between these points involves using the MIA Mover to the Miami Intermodal Center, then taking the Metrorail to Government Center, and finally a bus or taxi to the port, a journey that can exceed an hour during peak demand.
Addressing Specific Needs of Cruise Passengers
The study highlights specific challenges in the cruise market: passengers often travel with substantial luggage, prefer door-to-door transfers, and their travel patterns are concentrated at specific embarkation and disembarkation times.
A key opportunity noted is facilitating luggage transfer from the airport to the port, providing seamless handling similar to airport-hotel shuttle services, which could make the transit more appealing by easing the passenger's burden.
Airport CEO Ralph Cutié acknowledged at the "State of the Port" event in April 2026 that "Metro Rail systems are quite expensive, and we need to assess their economic viability."
Strategic Importance for Miami-Dade's Economy
Internationally, Vancouver's Canada Line on the SkyTrain, connecting the airport to the cruise port in 25-26 minutes since 2009, serves as a frequently cited benchmark for such a direct connection.
For short-term solutions, the study suggests implementing branded PortMiami shuttles from key stations, integrated fares with a single ticket, improved tourist signage, and agreements with cruise lines to include transit in the cruise fare.
The project is categorized under "Priority IV" in the county's Long Range Transportation Plan 2050, indicating it lacks secured funding and its execution will depend on political decisions and budget priorities.
Mayor Daniella Levine Cava emphasized the strategic importance of these infrastructures by stating, "14% of the state's economy is here in Miami-Dade, with the port and the airport," reinforcing the urgency to enhance connectivity between the airport and port in anticipation of projected growth in the coming decades.
FAQs on Miami's Proposed Airport-Port Train Connection
What are the two proposed options for the train connection?
The two proposed options are a 10-mile extension of the Metrorail and a 9-mile automated people mover system, similar to MetroMover.
Why is the train connection between Miami's airport and port important?
Improving connectivity is crucial due to the increasing number of passengers at both the airport and port, and the current lack of a direct and efficient transit option.
What is the expected annual passenger usage by 2050?
The study projects an annual passenger usage of between 1.1 and 2.1 million by 2050.
