Use of Lighting Architectural lighting was very important in the overall design concept for the gateway and influenced the design of the vertical elements and the guardrail walls. The custom Haw Creek Bridge integrates 10, 27-foot tall spires into the bridge railings that extend down to the top of the bridge abutments. The spire and outer "wing panels" feature precise laser cutouts. The shapes of the perforations are mechanical parts fabricated from local manufacturer Noblitt Fabricating, Inc. The cutouts create shadows and patterns on the element during the day and were designed to take on a different effect at night. Two narrow- beam Jet luminaires with a 3000K LED color by Ligman Lighting USA are mounted behind the perforated panel 'wings' to backlight the cutouts. Custom mounting was designed so that the fixture could be installed through the access door on the trail side. An up light, 'Odessa 2' LED floodlight, also by Ligman, is hidden in a niche at the upper body of the element to illuminate the upper spire from the trail side. A recessed channel is designed into the face of the vertical element to accommodate a pair of ModaLight Super Neon Edge light strips that offers a solid line of light in 2700K color temperature. All internal wiring is accessible through the integrated locked access doors at trail level. 1: Haw Creek Bridge now accommodates a 10' wide trail on the north side (pictured), and a 6' wide sidewalk on the south with a protective barrier between traffic and pedestrians. The short outside railings were replaced with a 54" custom cable railing. The vehicular guardrail (left) has a 26" tall cast-in-place concrete base and a red powder coated steel rail mounted on top. 2: The spire and outer 'wing' panels of the vertical elements have precise rectangular laser cutouts laid out in geometrical patterns. An Odessa 2 LED floodlight is hidden in a niche of the upper body of the paneling to illuminate the metal from the backside. Two narrow-beam Jet luminaires with 3000K LEDs are mounted behind the perforated panel wings to backlight the cutouts. 3: A recessed channel in the vertical element accommodates a pair of ModaLight Super Neon Edge light strips that create a solid line of light in 2700K color temperature. 4: The 5 wall-recessed luminaires (11-watt LED lamps) set into the concrete bases are vandal resistant and energy efficient.
