Anyone who has flown through Tampa International Airport recently may have noticed that something very large is beginning to rise northwest of the Main Terminal.
For much of the early construction period, Tampa International Airport's Airside D project was happening at ground level. Crews removed old concrete, installed utilities, prepared foundations and handled the enormous amount of work necessary before a building of this scale could start taking shape.
Now, you can actually see it.
Structural steel began rising in May, and by August, concrete platforms were appearing throughout the steel framework. A second crane arrived in July to help assemble the more than 7,300 steel members that will eventually form the structure. Precast concrete panels that will begin enclosing the exterior are scheduled to start going up in September.
The construction progress makes this a particularly interesting moment for Tampa International Airport.
Airside D isn't simply another renovation inside an existing terminal. It will be TPA's first new Airside in almost 20 years, its largest Airside when completed, and a critical piece of the airport's plan for handling millions of additional passengers expected to travel through Tampa in the coming years.
For Tampa Bay, the project is also something larger.
You can see the region's growth being built in steel and concrete.
Airside D Is a $1.528 Billion Project
The scale of Airside D becomes much easier to understand once you get beyond the renderings.
The final design approved in February puts the project's estimated cost at $1.528 billion. The building itself will cover approximately 600,000 square feet, making it the largest Airside terminal on Tampa International Airport's campus.
Sixteen gates are planned for the new facility, which will accommodate both domestic and international flights.
Airside D will have two main levels plus a mezzanine. Plans include a new TSA security checkpoint, shopping and dining, two airline lounges, a dedicated international arrivals processing facility and a new shuttle system connecting passengers with the Main Terminal. Delta Air Lines has been announced as the anchor tenant and plans to operate a Sky Club in the new facility.
The project broke ground in December 2024 and is scheduled to open to passengers in 2029.
That makes the construction happening throughout 2026 an important transition.
The airport spent much of the project's earlier stages preparing the site.
It's now building the airport Tampa will actually use.
The New Airside Is Finally Going Vertical
Airside D reached one of its most visible milestones in May when crews began erecting structural steel.
Building the frame is a massive undertaking on its own. More than 7,300 individual steel members weighing approximately 6,200 tons will eventually form the structure. TPA initially brought in a 300-ton crane to begin assembling the frame, with the steel erection process expected to take roughly nine months.
By early August, crews had progressed to the sixth of 19 steel assembly sequences.
Concrete was also beginning to fill in the structure.
Workers have been pouring concrete platforms over reinforced metal decking on multiple levels while completing portions of the ground floor and the enormous aircraft apron surrounding the terminal.
The apron alone provides some perspective on the engineering involved.
Aircraft weighing hundreds of tons require considerably more than an ordinary concrete surface. TPA says the new apron will use 18-inch-thick concrete, with almost 85,000 cubic yards ultimately expected to be poured for that portion of the project.
This isn't construction hidden behind drywall inside an airport people already know.
The physical footprint of TPA is changing.
Even the Old Concrete Is Becoming Part of the New Airport
One of the more interesting details of the project is happening underneath the finished building.
The area where Airside D is being constructed previously contained aircraft pavement. Instead of hauling all of that demolished concrete away, crews have been crushing it onsite and reusing the material as aggregate beneath new construction.
That recycled concrete is being incorporated underneath portions of the new terminal floor and aircraft apron.
It's the kind of construction detail most passengers will never notice once the terminal opens.
Thousands of people will eventually walk through a polished new international terminal without realizing portions of the former airport infrastructure are literally underneath them.
For a project this large, those behind-the-scenes decisions matter. They affect material movement, waste, construction logistics and the amount of new aggregate required for the site.
A New Shuttle Route Is Already Taking Shape
The terminal isn't the only structure becoming visible.
Passengers will need a way to travel between the Main Terminal and Airside D, which means TPA is also constructing a new automated people mover system and guideway.
Crews reached another major milestone this summer when they began installing steel and concrete supports spanning George J. Bean Parkway. Some of the guideway spans reach approximately 160 feet, with individual steel girders weighing up to 80 tons.
By August, the final steel and concrete guideway beams had been placed, and crews were beginning work on the running surfaces for the future shuttles as well as infrastructure supporting baggage delivery.
That's significant because TPA's shuttle-based design is one of the airport's defining features.
Rather than abandoning that system as the airport expands, Airside D extends it.
The Tampa airport of the future will feel familiar in some important ways, even though its capacity will be considerably larger.
Why Does Tampa International Airport Need Another Airside?
The simplest answer is people.
TPA says approximately 25 million passengers traveled through the airport in 2024. Its Master Plan projects annual passenger traffic approaching 35 million by 2037.
That's roughly 10 million more passengers moving through the airport every year.
Existing terminals, ticketing areas, baggage systems, roadways and gates have physical limits. Eventually, improving efficiency within the same footprint isn't enough.
Additional capacity has to be built.
Airside D is the centerpiece of the third and final phase of Tampa International Airport's current Master Plan, which was developed to reduce congestion and prepare the airport for future passenger demand. Earlier phases delivered projects including the Rental Car Center, SkyConnect automated people mover, roadway expansion, Blue Express Curbsides, Main Terminal improvements and SkyCenter One.
Airside D tackles one of the biggest remaining pieces of that growth plan: gate capacity.
Tampa Bay Is a Much Bigger Region Than It Used to Be
Airport expansion doesn't happen independently of the place an airport serves.
Tampa Bay has spent years adding residents, businesses, corporate investment, major developments and visitors. That growth eventually shows up at TPA.
New residents travel to see family. Companies bring employees and clients into the region. Conventions generate passenger traffic, while vacationers use Tampa as the gateway to beaches, attractions, cruises and destinations throughout West Central Florida.
An airport has to absorb all of those patterns simultaneously.
That's what makes Airside D an interesting Tampa Bay development story rather than simply an aviation story.
Infrastructure tells you what a region expects from its future.
Tampa International Airport isn't investing more than $1.5 billion because today's passenger traffic requires a shiny new terminal. It's building capacity for the Tampa Bay it expects to serve a decade from now.
International Travel Is a Major Part of the Plan
Airside D is particularly important for TPA's international operations.
The new terminal will contain a dedicated U.S. Customs and Border Protection facility designed to process arriving international passengers. International travelers will be able to move from their flights into a purpose-built arrivals area rather than relying entirely on facilities designed around the airport's existing capacity.
The design includes a secure arrivals corridor around portions of the terminal that directs international passengers toward Customs processing.
That additional infrastructure matters if Tampa wants to continue expanding its role as an international gateway.
Airlines considering new routes have to look at more than whether people want to travel between two cities. Airport capacity, gate availability, passenger processing and the ability to efficiently handle international arrivals all become part of the equation.
Airside D gives TPA significantly more room to grow that side of its business.
The New Terminal Is Being Designed Around the Passenger Experience
Capacity may explain why Airside D needs to exist, but TPA isn't designing it as a giant waiting room with 16 gates.
The final design includes a central area known as the Oasis, along with extensive greenery, dining and shopping, a dedicated children's play area, a quiet room and numerous power outlets for travelers. The airport is also planning its first sensory room as part of the project.
Two lounge spaces will occupy the mezzanine level, including the Delta Sky Club.
Glass passenger boarding bridges are planned to preserve views of the airfield as travelers board aircraft, while large windows and open interior spaces are intended to bring natural light into the terminal.
These details are significant because airports increasingly compete on experience as much as infrastructure.
For many visitors, Tampa International Airport is their first physical interaction with Tampa Bay.
The airport is effectively part of the region's front door.
Airside D Is Also a Huge Construction Story
A $1.528 billion airport project involves far more than constructing a building shell.
TPA describes Airside D as a collection of interconnected projects involving the terminal itself, shuttle guideway, aircraft apron and fueling infrastructure, passenger boarding bridges, baggage systems and automated people movers.
Utilities are being installed throughout the construction site. Elevators and escalators are already being fabricated. Road alignments are changing to accommodate service access, while baggage infrastructure has to connect the new Airside with the rest of the airport.
Meanwhile, airport operations continue around the construction.
Planes still have to move. Passengers still have flights to catch, airport employees need access to their workplaces, and construction activity has to coexist with one of the busiest transportation facilities in the region.
That complexity is part of what makes airport construction so different from developing an ordinary commercial property.
The jobsite can't simply take over the site.
The airport has to keep working around it.
The Investment Extends Beyond Airside D
Airside D may be TPA's most visible construction project, but it isn't the airport's only major investment.
The Hillsborough County Aviation Authority's fiscal year 2026 capital program includes 34 projects totaling approximately $835.5 million. Among them are a $298.6 million modernization of the airport's checked baggage system and a $285.7 million expansion and renovation of the Main Terminal Ticketing Level.
The baggage project is intended to create a more centralized system serving all of TPA's Airside terminals, with completion currently scheduled for late 2028.
Ticketing Level improvements are designed to add counter space, reorganize airline offices and create more room for passenger queues and check-in kiosks. That project is currently scheduled for completion in late 2029.
Put those projects together and the scale of TPA's transformation becomes clearer.
Airside D isn't being attached to an airport that otherwise stays frozen in place.
Multiple parts of the passenger journey are being rebuilt for higher capacity.
Major Airport Growth Creates Business Opportunities Too
Infrastructure spending at this scale creates economic activity far beyond the airport's own employees.
Design, engineering and construction are obvious beneficiaries during the building phase, but the opportunities continue once the terminal opens.
Sixteen additional gates create space for airline operations and the businesses supporting them. New concessions mean opportunities for restaurants and retailers. Larger passenger volumes can support transportation companies, hospitality businesses and other companies serving travelers throughout Tampa Bay.
TPA has specifically identified opportunities for small and disadvantaged businesses as Airside D progresses, including contracting and future shopping and dining operations.
The economic impact can also extend outside airport property.
A larger airport capable of supporting more passengers and international service makes Tampa Bay more accessible to visitors, employers, investors and event organizers.
Airports don't create regional growth by themselves, but they can make that growth easier to sustain.
September Will Bring Another Visible Change
One of the next construction milestones is scheduled to happen this month.
TPA says precast concrete panels are expected to begin going onto the exterior of Airside D in September.
That will change what people see from nearby roads and the existing airport.
Steel framing shows the shape of a building. Exterior panels begin making it look like one.
The construction timeline currently calls for Airside D to reach approximately 75 percent completion by late 2027, with substantial completion expected in late 2028. Passengers are scheduled to begin using the new terminal in 2029.
There is still a lot of work ahead.
But we're past the point where Tampa Bay has to imagine what this expansion might look like.
It's rising out of the ground.
Tampa International Airport Is Building for the Region Tampa Bay Is Becoming
Airports are unusual pieces of infrastructure because their growth reflects so many other things happening around them.
Population matters. Tourism matters. Business investment, conventions, international connections and the attractiveness of a region as a place to live all eventually influence passenger demand.
TPA's expansion is therefore another useful measure of Tampa Bay's trajectory.
The airport that comfortably served this region years ago isn't necessarily the airport capable of serving it in 2037.
Airside D is being built to close that gap.
By the time passengers begin boarding flights there in 2029, the steel, cranes and concrete visible today will have become another ordinary part of traveling through Tampa.
Right now, however, we're getting to watch one of Tampa Bay's biggest infrastructure projects take shape in real time.
And every new floor makes the scale of what's coming a little harder to miss.
Tampa Bay Is Building for What's Next
The transformation happening at Tampa International Airport is one of many signs that this region is preparing for another decade of growth.
For Tampa Bay businesses, that growth means a larger market, more visitors and new opportunities. It also means competing for attention in a region where customers have more choices than ever.

FAQs
-
Tampa International Airport is expanding because its existing facilities need additional capacity to accommodate the region's expected passenger growth. TPA handled approximately 25 million passengers in 2024, and the airport's Master Plan projects annual passenger traffic could approach 35 million by 2037.
Airside D addresses that growth by adding 16 gates capable of serving domestic and international flights. The roughly 600,000-square-foot terminal will also provide additional security, baggage, customs, dining, retail, lounge, and passenger-processing capacity.
The expansion reflects a larger change happening throughout Tampa Bay. Population growth, tourism, business investment, conventions, and increased demand for air service are putting more pressure on the region's transportation infrastructure. Airside D is being built around the number of travelers TPA expects to serve in the future rather than waiting for the existing airport to reach its limits.
-
Airside D is currently scheduled to open to passengers in 2029. Construction began following the project's December 2024 groundbreaking, and work became considerably more visible during 2026 as structural steel, concrete floors, the shuttle guideway, and other major components began taking shape.
The current construction schedule calls for the project to reach approximately 75% completion by late 2027, with substantial completion expected in late 2028.
A project of this size involves much more than completing the terminal building. Crews also have to construct and integrate baggage systems, passenger boarding bridges, aircraft infrastructure, utilities, security facilities, international arrivals processing, and a new automated shuttle connection to the Main Terminal before passengers can begin using the Airside.
-
Airside D is being designed to accommodate both domestic and international flights, with dedicated infrastructure for processing international arrivals.
Plans include a new U.S. Customs and Border Protection facility and a secure arrivals corridor that will direct international passengers from their aircraft into the appropriate processing area. This gives TPA additional capacity to handle international service as passenger demand grows.
The additional gates could also give the airport more flexibility as it pursues future air service. Airlines evaluating potential international routes consider factors beyond local passenger demand, including available gates, airport capacity, connecting infrastructure, and the ability to efficiently process arriving passengers. Airside D strengthens the physical infrastructure Tampa needs if its international route network continues expanding.
-
Airside D is the centerpiece of TPA's current expansion, but several other major infrastructure projects are underway or planned as the airport prepares for higher passenger volumes.
The airport's fiscal year 2026 capital program includes a major modernization of its checked baggage system and an expansion and renovation of the Main Terminal Ticketing Level. The baggage project is intended to create a more centralized system serving the airport's Airsides, while ticketing improvements will add counter space and create additional room for passenger queues and check-in kiosks.
Together, these investments address different pressure points in the passenger journey. Adding gates alone wouldn't solve future capacity problems if baggage handling, ticketing, security, or other airport systems couldn't accommodate the additional travelers using them.
-
A $1.528 billion terminal expansion is a significant indication of how much passenger demand Tampa International Airport expects the region to generate over the next decade.
Tampa Bay's airport traffic is influenced by more than tourism. Population growth creates additional travel demand from residents, while corporate investment and business activity bring employees, clients, and investors into the region. Conventions, sporting events, cruise traffic, beaches, and other attractions add another substantial source of visitors.
That makes Airside D more than an airport construction project. It is infrastructure being built around expectations for a larger, busier, and increasingly connected Tampa Bay. By creating capacity before projected passenger demand reaches existing limits, TPA is preparing for growth that could shape the region well beyond the airport property itself.
