Exciting developments on the horizon for airports in the United States: Prepare for a revamped air travel experience.
In 2025, the airport industry is currently undergoing a pivotal moment with investments in modernization and expansion surpassing USD 1 billion. Fueled by the “Infrastructure Investment and Jobs Act” (IIJA) and the escalating demand for more advanced services, these large-scale projects are aimed at enhancing the passenger experience, boosting operational capacity, and promoting sustainability. The following are the most notable initiatives that are set to revolutionize the sector.
Highlighted Projects Redefining Infrastructure
The John Glenn International Airport in Columbus, Ohio, is at the forefront of transformation with a $2 billion project that includes the construction of a modern terminal spanning 92,900 m² and a parking facility capable of accommodating 5,000 vehicles. The new terminal, designed to cater to over 13 million passengers annually, will incorporate seven extra gates and innovative spaces such as a central market, iconic entrances, and a pedestrian bridge. Led by Hensel Phelps, the project commenced in late 2023 and is projected to be finalized by 2029, marking a significant milestone in Ohio’s aviation history.
Pittsburgh International Airport is undergoing a transformation with an investment of $1.57 billion, featuring a distinctive terminal that consolidates all operations under one roof, along with an upgraded road network and multi-level parking facility. Inspired by the local environment, the design includes tree-shaped columns and sustainable materials like local wood and efficient glazing. The endeavor aims to reduce greenhouse gas emissions by 20% by 2028, with ongoing focus on the interior following the completion of the exterior.
Tampa International Airport is gearing up for the future with a new terminal as part of its $1.5 billion expansion, catering to the anticipated regional growth of 35 million annual passengers by 2037. The Airside D terminal, boasting 16 gates for international flights, is slated to open in 2028, emphasizing commercial spaces and passenger processing areas.
Sustainability and Expansion: Cases in Nashville and Sacramento
The Nashville airport is embarking on a $1.5 billion “New Horizons” plan, encompassing expansions, runway system enhancements, and road modernization to meet the surging passenger demand by 2028.
Meanwhile, the Sacramento airport is implementing improvements amounting to $1.3 billion, which include a pedestrian walkway adorned with public art and a parking facility with over 5,500 spaces, equipped with electric vehicle chargers. These innovations are anticipated to be operational by 2026, setting a new benchmark in airport design.
Newark Liberty International Airport: Long-Term Planning
With almost a century of operation, Newark Liberty airport is planning to replace its terminal B, upgrade terminal C, and revamp roads and runways. Although final costs are pending definition, the project has already secured $55 million for preliminary designs, marking the commencement of a comprehensive modernization effort.
Future Outlook for Airports
These mega-projects will not only reshape the immediate passenger experience but also establish the foundation for the future. Through the integration of technology, enhanced operational capacity, and bioclimatic design, these airports will adapt to the escalating air traffic and the preferences of environmentally conscious travelers. Nonetheless, these initiatives pose significant challenges in terms of financial planning and logistics. Each remodeled terminal, expanded parking facility, and restructured road system will represent a milestone in the development of airport infrastructure, reinforcing the United States’ dominance in this critical sector.
