    The structural design, with its sinuous form, required careful study to ensure that the bridge was properly and sensitively illuminated. Concealment of fixtures, minimizing disability glare, and maintainability were all key issues.

    The goal of the lighting design for the bridge’s approach was to graphically illuminate the form of the arches, which are lit white, in contrast to the suspended pedestrian walkway, which is lit with a less obtrusive blue light.

    Cantilevered brackets from the deck hold white metal-halide fixtures that carefully illuminate the majority of the arch with very fine rotatable, lenticular lenses to generate a very thin line of light. Each fixture is carefully aimed onto the structure, overlapping the lines of light, ensuring that the form of the bridge is expressed, guaranteeing minimal light trespass.

    The fixtures and lenses on the handrail were locked into place to ensure future foolproof maintenance. The hinged brackets were designed to allow the cantilever arms to be pulled up to the edge of the deck where maintenance can be carried out easily with no safety equipment required. The walkway is lit by custom LED fixtures, which are located below the handrail. Each has two blue and two white 1W LEDs and a durable radar sensor.

    The bridge is normally lit blue. As a person activates the sensor, the white LED in the unit changes from blue to white with a one second fade. As soon as the sensor loses contact, the white LED cross fades back to blue over four seconds. This effect gives people who cross the bridge, the feeling as if they are leaving a comet trail of light behind them.

    At each end of the arch, the structure touches down almost to a point mid-way within the pedestrian walkway. It was critical to the design that the lit structure should continue all the way down to this “cool” connection. Recessed metal-halide fixtures in the deck graze up the structure to ensure this continuity exists.

    Blue metal-halide fixtures directed downward onto the adjacent river walk engage with pedestrians walking along the rivers edge, and onto the water to create a curtain of light that engages rowers that regularly use the river for training.

Designed to encourage development in the areas on both sides of the River Tees in Stockton-on-Tees in northeast England, this bridge takes speculative design to a new level. The city wanted the bridge's image to be as powerful at night as it would be by day. So the designers worked with the client and the city to encourage pedestrian traffic.

The lighting design uses white and blue light, and the colors complement each other to outline the bridge's form. The bridge's main upper structure—a sinuous wave curve—is lit from end to end with metal halide sources positioned in cantilevered brackets mounted at the deck. The fixtures are concealed to minimize glare, but still allow for easy maintenance: The cantilevered arms are on hinged brackets and they can be pulled up and relamped without the need for additional equipment. The rotatable lenticular lenses produce a thin line of light, and aiming was key so that there is no light spill.

Along the walkway, the designers combined two blue and one white 1W LEDs with a durable radar sensor in a custom handrail. The combination creates an unexpected interactive feature, which is revealed when a person starts to cross the bridge: As the sensor is activated, the LED changes from blue to white with a one-second fade. When the sensor looses contact, the white LED cross-fades back to blue over four seconds and the pedestrian experience is completely transformed as people become “painters” and leave a trail of light behind them.

Jury Comments: The pedestrian experience through the entire crossing is considered, including the exit and entry points in and around at each end of the bridge. • The lighting engages with the individual.
