Major gate and baggage-handling expansion aims to increase capacity and enhance the passenger experience
For contractor Hensel Phelps, lead designer Corgan and Southwest Airlines program manager William Manning, the $470-million expansion of the west concourse at Houston’s William P. Hobby International Airport means coming full circle.
The team had built the original five-gate international terminal and Federal Inspection Station facilities for the Houston Airport System, completing them in 2015. Now, the reunited team is adding seven new gates, a modern baggage handling system with two additional carousels, and a weather-protective canopy connecting the parking garage to the terminal.
Hensel Phelps began work on the construction manager-at-risk project in 2024, topping out the concourse structure last fall. Completion is slated for 2027.
