Infinity Bridge, Stockton, England

Infinity Bridge in Stockton, England cuts an uncommon silhouette across the River Tees. It is a 230m long concrete structure supported by a pair of asymmetric steel arches that appear to skip across the river like a pebble skimming water.
The lighting is made  in such a way that the iconic twin arches reflect in the water at night to form the mathematical symbol for infinity.
The designers bounced blue light off the water to light the underbelly of the deck and form a blue zone above the water. Cold white light was used to reveal the structural form and create the sense of a floating wave hovering just above the deck..
Along the surface of the deck, light is responding to the presence of people, guiding them down the walkway or signaling  the approach of visitors. There are blue and white LED units concealed under the handrail. When people cross the bridge, the sensors trigger a change from blue to white, leaving a ‘comet’s trail’ of light in the pedestrians’ wake.
No other bridge is known to have quite the same design. Competing in the awards for Structural Engineering Excellence against over 100 global entries, the Infinity Bridge went on to win the overall Supreme Award.
