    In out of the rain at PDX


    The design for the bridges evolved from a linear to an S-shaped form in order to align the two existing structural cores where the elevator, stairs, and escalators are located. Changing the shape of the bridges made the physical connections more passenger-friendly and created a dynamic element within the large space.

    Fixed attachments anchor the canopy and skybridges to the parking garage, while flexible joints at the terminal building columns and bridge connections allow the structure to expand and contract with temperature changes. This design also accommodates structural movement during a potential seismic event.

    PDX has been one of the fastest growing airports in the United States. In order to accommodate such growth, the airport launched PDX 2000, a three-phase development program. This first phase improves access and increases close-in parking by enlarging and expanding the parking garage. The original three-story parking garage has expanded to seven levels, more than tripling in capacity.

    Inside the terminal, the main building's east wall moved 25 feet further east, enlarging the ticket-lobby and baggage-claim areas. In addition, new elevators, escalators, and stairs were built east of their previous locations to improve circulation.

    The goal of the program is to meet the demands of greater traffic while maintaining the superior facilities and service. The design solution illustrates how wayfinding can be improved at existing terminals.
