The Anaheim Regional Transportation Intermodal Center is a hub for rail, bus, auto and bike travel, and is also ready for high-speed trains and street cars. The Center serves three million Orange County residents and 40 million visitors annually. The terminal building, which houses a grand hall, ticketing and retail space, sits beneath a 250 feet long, 184 feet wide roof – a soaring, exposed steel structure of crisscrossing parallel arches which provide a high-tech take on the simple lines of old airship hangars and the light-filled grandeur of historic train stations.

Judge's comment:

The judges were impressed by the elegant and clearly legible diagrid arch structure, which has inherent structural stability and redundancy, and whose toroidal geometry helps to maximise its efficiency.  The way in which the tall curved glass end walls provide restraint to the roof and also support the cantilevered overhangs was also noted as being particularly successful.  Elegant detailing completes an altogether excellent structural design.
