The Port of Portland officially completed the $2.15 billion main terminal reconstruction at Portland International Airport on 30 June 2026, concluding an 11-year infrastructure program executed on-time and on-budget without a full airport shutdown. The redevelopment doubles passenger capacity to 35 million annually by 2045, adds 27% more gate capacity, and features a nine-acre mass timber roof sourced within 480km of the runway, establishing a distinct Pacific Northwest architectural identity. Phase II, the final phase, is now open with construction walls removed, delivering faster exits and a fully modernized passenger experience. While the main terminal is complete, ongoing improvements including baggage claim upgrades remain scheduled without specific future dates.
