The sky was the limit, and then the beam met it. On July 17, 2025, leaders from Houston Airports, United Airlines, Manhattan Construction and dozens of project partners gathered at George Bush Intercontinental Airport (IAH) to mark a major milestone in Houston’s largest active infrastructure project, the $2.55 billion transformation of IAH Terminal B.
The Topping Out Ceremony celebrated the placement of the final steel beam in the structural framework of the new Terminal B North concourses, marking the physical halfway point in a transformational redevelopment.
Terminal B is one of IAH’s original terminals, dating back to the airport’s opening in June 1969. This redevelopment—set for completion in fall 2026—represents a new chapter for Bush Airport and Houston.
Under high ceilings lined with fresh steel and flanked by sweeping airfield views, project partners recognized more than 1,300 workers for their role in shaping the future of travel through Houston. Many signed the final beam before it was hoisted, flanked by an evergreen tree and American flag — symbols of strength, tradition and safe construction practices. The surrounding structure is already taking shape, with floor-to-ceiling curtainwall glass enclosing what will soon become the concourses of the future.
Once complete, the IAH Terminal B Transformation will deliver a modern, intuitive travel experience. It will feature new technology, improved gate flexibility and the largest United Club in the airline’s system. It will also create expanded opportunities for concessions and global connections.
The construction project supports Houston’s broader goals of expanding international air service, attracting new routes and positioning IAH as a premier global gateway. Houston Airports is reinforcing its commitment to world-class infrastructure and sustainable passenger growth by increasing terminal capacity and operational efficiency.
The structure may have topped out, but the impact is still rising.
“This project is very important to the future of Houston,” said Jim Szczesniak, director of aviation for Houston Airports. “This is going to be a crown jewel in the aviation world,” Szczesniak said. “And a source of pride for the people of Houston for generations to come.”
