## Ambitious Terminal Transformation

Spokane International Airport has launched its $335 million Terminal Renovation and Expansion program, known as TREX. This massive project aims to modernize the facility by constructing a 255,000-square-foot Central Hall. The development will fundamentally change passenger navigation by centralizing security screening and baggage claim operations for all airlines serving the airport.

## Solving Connectivity Limitations

The current terminal layout forces many connecting passengers to exit the secure area and undergo TSA screening again when transferring between concourses. This physical separation between Concourse C and the main terminal complex creates unnecessary delays. The new Central Hall project is specifically designed to provide fully integrated airside circulation for travelers.

## Centralized Passenger Experience

Once completed, the Central Hall will serve as the heart of the airport, consolidating security checkpoints for all concourses. Passengers will be able to move between Concourses A, B, and C without returning to the public side of the terminal. This intuitive layout aims to reduce confusion and improve overall operational efficiency.

## Complex Utility Relocation

Before construction of the new building begins, crews must relocate vital underground utilities, including water, sewer, and gas lines. This preparatory work is essential to clear the site for the massive structure. These infrastructure adjustments have forced the airport to reorganize vehicle access and pedestrian pathways around the main terminal area.

## Traffic and Access Disruptions

Since October 21, 2026, a major portion of the terminal curbside has been closed to accommodate construction. Motorists are now directed through a temporary two-lane bypass road, which is expected to remain in place until 2030. This change reduces traffic capacity and may cause congestion during peak arrival and departure periods.

## Impact on Airline Operations

Airlines including Alaska, Allegiant, and American are directly affected by the decommissioning of the existing baggage claim in Concourse C. Passengers flying these carriers must now use a temporary baggage claim facility located in the Concourse C plaza. This interim arrangement will remain operational throughout the duration of the construction project.

## Parking and Passenger Advice

The airport's hourly parking lot is closed for construction staging, requiring travelers to use alternative parking options. Management recommends that passengers arrive at least two hours before domestic flights to navigate the new routes. Travelers should follow updated signage and utilize the Cell Phone Lot when picking up arriving friends or family.

## Foundation of Phase One

The Central Hall project follows the successful completion of the Concourse C expansion in June 2026. This earlier phase added 144,000 square feet, three new gates, and additional ticket counters to the facility. This initial investment provided the necessary operational capacity to support the airport while the more complex central terminal redevelopment proceeds.

## Future Construction Milestones

While site preparation is currently underway, the official groundbreaking for the Central Hall is scheduled for the second quarter of 2027. The airport must maintain normal flight operations throughout this multi-year process. The project remains a long-term commitment, with the current traffic and passenger arrangements expected to persist through the year 2030.

## Long-term Strategic Importance

The $335 million investment represents one of the most significant transformations in the history of Spokane International Airport. By addressing longstanding terminal design weaknesses, the airport aims to enhance its convenience for travelers across the Inland Northwest. Success hinges on delivering a seamless, consolidated experience that justifies the years of construction disruption.
