The MLIT (Mickey Leland International Terminal) Renovation and Expansion at George Bush Intercontinental Airport (IAH) encompasses a comprehensive modernization and capacity enhancement program aimed at transforming the existing international terminal into a unified, state-of-the-art facility capable of accommodating long-term passenger growth and evolving airline operations. The project scope includes the renovation of existing terminal spaces to improve passenger processing, security screening, customs and immigration facilities, and baggage handling systems, alongside the expansion of concourses, gate areas, and hold rooms to support additional wide-body aircraft and increased international traffic. Key elements involve upgrading building systems (mechanical, electrical, plumbing, and IT infrastructure), enhancing ADA accessibility, improving passenger amenities and concessions, and implementing energy-efficient and sustainable design features. The program also integrates airside improvements such as apron reconfiguration, utility relocations, and aircraft support systems, as well as landside enhancements including roadway modifications, curbside improvements, and connections to parking and ground transportation. Phased construction sequencing will be required to maintain ongoing airport operations, minimize passenger disruption, and ensure safety throughout the project lifecycle, ultimately delivering a cohesive, modernized international gateway aligned with Houston Airport System’s long-term strategic vision.
