Infinity  Bridge is a pedestrian footbridge across
the River Tees in the borough of Stockton-on-Tees
in England. Built at a cost of £15-million, it has
a pair of continuous structural steel arches with
suspended precast concrete decking and one
asymmetrically placed river pier. On the surface of
the bridge, light is programmed to respond to the
presence of pedestrians, guiding them down the
walkway with 200 custom made blue and white LED
units concealed under the handrail. As pedestrians
cross the bridge, sensors trigger a change from
blue to white, leaving a ‘comet’s trail’ in the persons
wake.
