Construction of Concourse K at Miami International Airport (MIA) is in its initial construction phase, following a ceremonial groundbreaking on June 24, 2025. The project represents a $600.6 million investment, funded through airport revenue bonds and state/federal grants, including $91.2 million from the FAA. The project also marks a major step in the airport’s $9 billion “Future-Ready Modernization in Action” initiative aimed at overhauling air travel infrastructure.

The development will transform the airport’s capabilities, delivering six new gates, an aircraft apron with a fuel hydrant system, and significant improvements to both ground operations and baggage handling. A new ground support equipment maintenance facility and two additional baggage make-up carousels are also part of the design. Importantly, upgrades will link the existing systems between the Central and South Terminals, boosting efficiency across the board. Once Concourse K is operational, the airport plans to demolish the aging Concourse G to make room for further Central Terminal expansion.

MIA like many US airports underaking upgrades has reached its operational ceiling, having served 56 million passengers and moved over 3 million tons of cargo in 2024 alone. With projections estimating passenger volume could reach 77 million and cargo up to 5 million tons by 2040, this expansion is not only timely — it’s essential. The airport has one of the longest airports in the USA at a length of 3900 metres allwoing the largest aircraft int he world to land.

Airport Director Ralph Cutie and his team, backed by the Board of County Commissioners and numerous aviation partners, are spearheading what they describe as a “future-ready investment” aimed at building an airport that meets the evolving needs of the region and the globe. “This isn’t just about more gates — it’s about reimagining how our airport can serve as a powerful economic engine, global gateway, and symbol of progress for Miami-Dade,” Cutie said in a statement.

Who’s Leading the Build?

The design and construction work will be led by Perez & Perez Architects Planners, Inc., with Lemartec-NV2A JV, LLC named general contractor for the project. Targeting LEED Silver certification, the project places a strong emphasis on sustainability and modern design practices.

Concourse K construction will play a central role in enhancing MIA’s infrastructure, allowing for greater operational flexibility, smoother passenger experiences, and improved turnaround times for aircraft. The addition also reflects a broader strategic vision: positioning MIA not just to grow, but to lead among the world’s premier international airports.

Tampa International Airport is also expanding with its Airside D terminal — which the Hillsborough County Aviation Authority approved for final design and funding in February 2026, clearing the way for construction to begin this year and a planned 2029 opening — highlighting a broader trend of major airport growth across Florida alongside Miami’s Concourse K project.
