To unify several new family-oriented neighborhoods and connect an extensive trail system in Irvine, Calif., a pedestrian/cycling bridge was developed to span a major boulevard that divides the developments. Breaking from the tradition of classic train-style bridges used elsewhere in the city, the team strove to create an iconic element that would inspire awe visually while making the overcrossing experience more exciting. Hidden linear LED RGBW fixtures by Lumenpulse wash the inside of each structure with colored light. Full color changing fixtures provides infinite flexibility for the appearance across the bridge, using DMX controllers. The team decided to keep things simple, however, and not regularly change color, rather, choosing impactful colors, changing them only for holidays and special events. Enhancing the main structural elements of a bridge, a series of gateways were created by steel paneled columns. The gateways increase in stature to build excitement as users travel toward the center of the development and the expansive sporting complex at its core. Lighting the interior of the metal structures without visible lighting fixtures showing provided a challenge to the team, as well as a study in the nature of lighting. Initial designs featured a recessed product between the bridge guardrail and the interior face of the gateway.

Hidden linear LED RGBW fixtures are mounted on the gateways below the guardrails to wash the interior walls of the gateways with colored lights. The top left image is the view to the south; the lower left image is the view to the north.
