The Modernization In Action Plan
Pardon our progress as MIA gets
Miami International Airport soared to unprecedented heights in 2024, marking a historic year of accomplishments in passenger and cargo traffic, as well as substantial investments in maintenance and capital improvements. MIA achieved its highest-ever annual passenger total, handling 55.9 million travelers in 2024, for an impressive 7% increase over the previous year's record.
MIA has been welcoming these record numbers on a 24/7 basis while simultaneously working to modernize each touchpoint along the passenger journey airport-wide, from the airplane cabin to the airport curb.
Through the Modernization in Action (M.I.A.) Plan, 126 passenger boarding bridges, 196 public bathrooms, and 600+ conveyance units (elevators, escalators, and moving walkways) are being renovated in phases over the next 5-7 years.
Aging areas require being out of service for up to a year for renovations or repairs. Out of MIA’s 330 elevators, 186 escalators, and 100 moving walkways, less than 10% are out of service for maintenance on an average day, but we know that may still disrupt your travel journey and we apologize for any inconvenience.
Under the leadership and guidance of Mayor Daniella Levine Cava, we are working diligently and ask that airport patrons please pardon our progress while we get MIA Future-Ready to keep you connected with more than 170 destinations across the world.
We appreciate your patience while the M.I.A. Plan makes traveling through MIA easier than ever before. Learn more about each project in the tabs below.
A modernization plan is underway to fully rebuild and/or replace most of the 616 conveyances at MIA (330 elevators, 186 escalators, and 100 moving walkways), which represents half of all the conveyance units at Miami-Dade County government facilities. To keep MIA accessible for those using wheelchairs, elevators have been prioritized for modernization and eight elevator units have already been completed. So far, 34 units have been upgraded, and another 38 units are under contract to begin the modernization process in 2023 and 2024.
A full conveyance modernization typically requires 16 to 20 weeks on average to accomplish the precision fabrication of replacement components, as well as the specialized equipment and rigging needed to remove and install extremely large parts in challenging locations. For example, a modernized 40-step escalator is comprised of over 12,000 moving parts.
As we install new and rebuilt devices, we have found it difficult to obtain parts because of continued supply chain delays. It is taking as long as eight months to receive parts. In addition, some of our devices are obsolete and parts literally are built from scratch. Additionally, routine maintenance and inspections are required, which further reduces the number of units in service. The remaining units will be in some stage of modernization within the next seven years.
What’s the first place most of us go to after a long flight? You guessed it – the bathroom. MIA’s restroom modernization project includes the renovation of 196 public access restrooms located on all three levels of MIA’s terminal and concourses. As of August 2025, 44 restrooms have been modernized.
Renovations include interior demolition, new partition walls, new toilet partitions, new restroom finishes including flooring, walls, ceiling, new vanity countertops, new plumbing fixtures, new accessories, and new lighting fixtures.
Phase 1, which included 10 public restrooms in Concourse H, was completed in Winter 2023.
Phase 2, which includes 22 restrooms in Concourse D, 12 restrooms in Concourses E, F, and G, and 16 public restrooms in Concourses H and J, is scheduled for completion by Fall 2026.
Phase 3, which includes the remaining bathrooms across the MIA terminal, is scheduled for completion in stages over the next six years.
Project Benefits:
Under the leadership of Miami-Dade County Mayor Daniella Levine Cava and with the support of the Board of County Commissioners, Miami International Airport’s $9 billion Modernization in Action (M.I.A.) maintenance and capital improvement program is on schedule to completely transform the global hub over the next 10 years. Renovation and expansion projects in the M.I.A. Plan are paving the way for the airport to welcome more than 77 million travelers and four million tons of freight by the year 2040.
The comprehensive future-ready program is designed to modernize every passenger touchpoint from the cabin to the curb and beyond through unprecedented investments, including a total redevelopment of the Central Terminal between concourses E and G, a new Concourse K that expands the South Terminal, renovated Concourse D gates to serve larger aircraft and more flights, a new four-star hotel with a business center and conference space, and upgrades to all of the airport’s elevators, escalators, moving walkways, and bathrooms.

A passenger's first step from the airplane to the airport is onto a passenger boarding bridge (PBB). MIA is improving that first impression by replacing or refurbishing all its 126 passenger boarding bridges. The first 32 bridges, including two glass bridges, have been installed. Another ten are pending solicitation. By 2028, 94 of MIA’s 126 bridges will be replaced.
This project also includes the design, fabrication, transportation, and installation of pre-conditioned air units, baggage chutes, and ground support equipment for each boarding bridge.
