Spokane International Airport Begins $335 Million Central Hall Project; Terminal Curbside Closed Until 2030 Bypass
Why It MattersLarge regional airports are rebuilding terminals around a single consolidated checkpoint and baggage hall, accepting years of reduced curbside capacity and temporary facilities while the work proceeds.
Spokane International Airport (GEG) is building a 255,000-square-foot (23,690 square meter) Central Hall, an estimated $335 million project that forms the centerpiece of Phase 2 of its Terminal Renovation and Expansion (TREX) program. The building will consolidate security screening and baggage claim into one facility, with a centralized checkpoint serving all airlines and a post-security connection linking Concourses A, B and C. The aim is to end the need for some connecting passengers to leave the secure area and clear TSA screening again.
To prepare the site, crews must first relocate underground water, sewer and gas utilities. On October 21, 2026, a major portion of the main terminal curbside was closed to vehicles and pedestrians, and all vehicle traffic is now routed through a newly built two-lane bypass road expected to remain in place until 2030. The Spokesman-Review reported that the airport previously had three inbound traffic lanes, so the temporary layout reduces capacity. Pedestrians using the parking facilities must reach the terminal through the sky bridges.
The existing Concourse C baggage claim is being decommissioned and demolished. Passengers on Alaska Airlines, Allegiant Air and American Airlines, which operate from Concourse C, will collect checked bags at a temporary baggage claim in the Concourse C plaza, expected to be used through 2030. The hourly parking lot has been closed for construction staging; the airport recommends the first floor of the parking garage for stops under two hours and the Cell Phone Lot for those waiting to collect arriving passengers.
