In Fall 2019, Portland International Airport (PDX) bid farewell to a dim, crowded Concourse A, demolishing this aging wing of the airport in favor of a bright, airy, and more modern Concourse B. The completely redeveloped and expanded concourse, which opened to travelers in December 2021, complements the ongoing redevelopment of PDX’s main terminal (with phase one of the project opening in spring 2024 and final completion in December 2025), continuing its calming passenger experience with Pacific Northwest-influenced design elements throughout.
A two-story addition features 10 new arrival/departure gates serving Alaska Airlines and their subsidiary Horizon Air. The double-height volume allows passengers to easily locate their gates as they descend from the upper level—with two concession areas stacked vertically to make all options visually accessible.
The concourse was designed with a strong connection to nature to increase the quality of the passenger experience and reduce the stress of traveling. Full-height windows offer expansive views out to the airfield and increased natural light which filters through the interior plantings with exterior sunshades that provide maximum comfort. Daylight optimization went beyond the façade design; the ceiling is designed to hit the optimal level of light reflectance value (LRV), a process that involves the color, perforation size, surface glossiness, and selection of light fixtures. The design allows daylight to penetrate deep into the space to further improve passenger comfort.
Importance was placed on the selection of sustainable and locally sourced materials, examples of which are featured prominently throughout the concourse. Along the main circulation of the double-story space, 9,000-board-feet of FSC-certified Oregon White Oak was sourced from within a 60-mile radius of Salem, Oregon. The wood provides acoustical benefits which balance the hard terrazzo flooring, contributing to volume control for greater passenger comfort. Hold rooms also feature the iconic “PDX carpet”, which the airport is well-known for, offering both comfort and familiarity. A wood ceiling in the main circulation area serves to differentiate the space from the ceiling tiles in the hold rooms.
Pacific Northwest-inspired biophilic—or nature-based design elements—reference Oregon flora and are part of the elevated new washroom design incorporated throughout the airport. The entry to the restrooms in Concourse B is marked by graphic, oversized, mosaic ferns in calming shades of green.
