IAH Terminal B Update: Houston’s bold blueprint for the future of travel
From steel beams to glass walls, IAH's $2.5 billion transformation is now visible in the skies—and on the ground—redefining the way Houston connects.
Jun 18, 2025
Aerial photos of George Bush Intercontinental Airport (IAH) from May 2024 show a bare apron, scattered dirt patches and early groundwork.
Twelve months later, June 2025 imagery reveals dramatic change: a sprawling dual-pier steel structure, newly installed curtain wall glass and a maze of cranes and support vehicles humming across the tarmac.
From the ground, the transformation is even more striking. Glass now stretches across the new Terminal B North concourse, catching reflections of the sky and signaling the terminal’s future form. Massive cranes tower above the construction zone as workers install roof decking, shape exterior cladding and guide heavy steel into place. Progress is layered: steel above, concrete below, and nonstop movement in between.
The Terminal B Transformation is no cosmetic upgrade. Led by United Airlines in partnership with Houston Airports, the project is a complete overhaul that will :
• Add 22 new gates on the Terminal B North concourses, boosting Terminal B passenger capacity. • Upgrade 18 gates at Terminal B South with passenger boarding bridges. • Double the size of the central processing facility used for check-in, TSA and baggage claim. • Expand check-in and baggage halls to handle 36 million passengers annually.
The future is beginning to take shape—literally. The new processor will feature more than 1,000 glass panels. Each panel measures approximately 5 feet wide by 15 feet tall, and the glass height from ground to top will expand up to 45 feet. Once completed, the new Terminal B processor will feature 67,000 square feet of glass, including an unobstructed view of the new Ticketing Hall.
The pace of construction is especially noteworthy considering the airport's record-setting traffic. In 2024, Bush Airport served 48.4 million passengers—its highest annual total to date. United Airlines alone accounted for 34.8 million of those travelers. Construction at Terminal B has advanced through a year of record-breaking summer crowds, as well as busy holiday travel periods, including Thanksgiving and Christmas. The ability to maintain this momentum while delivering daily service at one of the nation's largest hub airports reflects unprecedented coordination, planning and execution.
Terminal B has long been among IAH’s oldest, with the airport celebrating 56 years of operations this June. The terminal’s rebirth positions Houston for even more international markets and global connectivity.
The transformation remains on track to finish by fall 2026. As the steel rises and glass gleams, Houston is making a statement grounded in construction: this city builds not just for today, but for the world it’s ready to welcome.
