The Anaheim Regional Transportation Intermodal Center (ARTIC) provides Southern California with a flexible, futuristic terminal for rail, bus, auto passengers, bicyclists, and pedestrians. The illustrative design concept of diamond-shaped steel arches infilled with translucent ETFE (ethylene tetrafluoroethylene) creates a grand, light-filled atrium reminiscent of the world’s great passenger terminals of the early-20th century.
