Inside RDU's $2.5 Billion Expansion: What's Coming to Raleigh-Durham's Airport

Raleigh-Durham International Airport is in the middle of the biggest expansion in its history — more than $2.5 billion toward new runways, larger terminals, and more. The reason is simple: passenger traffic is exploding. RDU handled roughly 15.5 million passengers last year, and by 2035 it expects to reach nearly 30 million annually. To prepare, almost every part of the airport is changing.

This post walks through what's being built and why it matters for the region. You can also watch the full breakdown here: Inside RDU's Expansion (YouTube).

Why Now?

The Triangle has become one of the fastest-growing metro areas in America, and that growth is fueling massive demand for air travel. RDU now serves around 80 nonstop destinations — the most in its history — and international traffic is climbing even faster, with more than 1.5 million international passengers in 2024, a major jump over pre-pandemic levels.

Airport officials say the original infrastructure simply wasn't built for this level of growth. RDU has earned a reputation as one of the easiest airports in the country to fly through, thanks to short security lines and low crowds, and the goal is to keep it that way. That's the thinking behind its long-term modernization plan, Transform RDU — and its centerpiece is a brand-new runway.

A New Runway Built for Long-Haul Flights

RDU is building a completely new runway, designated 5L/23R, stretching more than 10,000 feet — long enough to handle larger aircraft carrying heavier fuel and cargo loads. That capacity is critical for future long-haul international service.

The airport is also relocating and extending portions of the airfield to add spacing between the runway and Terminal 2. Per planning documents, one runway section will shift more than 500 feet further from the terminal area to improve operational flexibility and make room for future terminal expansion. Crews are already relocating utilities, rebuilding drainage systems, and rerouting nearby roads. The runway is expected to open around 2029, and once complete, it will significantly increase flight capacity while reducing delays during peak travel periods.

Rebuilding Terminal 2

At the same time, RDU is rebuilding major portions of Terminal 2. Construction began with the installation of large floor-to-ceiling walls inside the terminal while crews expand the building behind them. The project includes a larger ticketing hall, expanded TSA checkpoints, bigger baggage claim areas, more international arrival capacity, and upgraded baggage handling systems. Terminal 2 will stay operational throughout, but travelers should expect years of visible construction.

There's a clear reason this is happening now: international growth has accelerated dramatically. RDU now serves 14 international destinations and keeps adding more — an unusually aggressive expansion for a mid-size U.S. airport, and one that's forcing the airport to rapidly scale up its international processing capacity.

The New Flights Driving the Boom

So where are all these new routes going? Some of the most significant recent additions include:

• Lufthansa to Frankfurt, Germany — a direct link into one of Europe's largest global airline hubs.
• Aeroméxico to Mexico City, opening direct connectivity into Latin America.
• Copa Airlines to Panama City, giving travelers easier one-stop access across Central and South America.
• Air Canada to Vancouver and WestJet to Calgary, marking major growth into Canada.
• Avelo Airlines launching RDU's first nonstop flights to Montego Bay, Jamaica, and Punta Cana, Dominican Republic, as low-cost carriers expand aggressively.

Domestic growth has kept pace, too. RDU recently crossed the 80-nonstop-destination milestone after Breeze Airways added new service, with additional routes recently added or announced to Atlantic City, Birmingham, Madison, and San Antonio, among others. Airlines increasingly view Raleigh-Durham as a high-growth market with strong business demand and rising international traffic — exactly why the infrastructure is being expanded so aggressively.

Fixing the Roads

One of RDU's biggest challenges isn't the runways — it's the roads. Anyone who flies through Terminal 2 regularly knows how brutal traffic backups get during peak hours. So the airport is launching a $175 million roadway expansion, which includes widening John Brantley Boulevard from two lanes to four, rebuilding the Terminal 2 departure bridge, redesigning intersections near International Drive, and expanding curbside capacity. At points during construction, portions of Terminal 2's upper-level access may close entirely for extended periods. Officials say the upgrades are necessary because the current roadway system was never designed for volumes approaching 30 million travelers a year.

More Parking, Too

Parking is also being massively expanded. Economy Lot 3 is growing by roughly 3,800 spaces to around 11,000 total. The airport is adding more EV charging stations, expanded shuttle operations, new customer service facilities, and sustainability upgrades for stormwater runoff. In short, every major system at RDU is being scaled up at once.

What's Next

RDU's transformation is a clear signal of where the Triangle is headed — a region growing fast enough that even its airport can't expand quickly enough to keep up.
