This is the footbridge over the River Tees designed by Expedition Engineering for Stockton-on-Tees Council. Speirs and Major Associates designed the lighting in such a way that the twin arches reflect in the water at night to form the mathematical symbol for infinity (∞).

The light concealed under the handrail is a custom designed LED product manufactured by ACDC Lighting. Each unit uses max. 3W for both colours, but seeing as the blue and the white are never on at the same time, the true figure is closer to 1.5W for each unit. There are approx. 200 units lighting the deck of the footbridge.

The video shows how the lighting reacts to the presence of people, leading them down the bridge and signaling the presence of oncomers. Blue and white LED units are installed under the handrail. When people cross the bridge, handrail sensors trigger a change from blue to white, leaving a comets' trail of light in the pedestrians wake.
