Architecture + Environment

Designed by Expedition Engineering and architect Stephen Spence, this slender bowstring bridge in Stockton-on-Tees cuts a distinctive silhouette, inspired by the movement of a pebble skipping across water.

Our design creates a strong reflection of the asymmetric steel arches in the water, forming an image of the bridge at night that appears to be the mathematical symbol for infinity (∞) – hence the name.

Highly regarded locally, when it first opened the deck lighting trended on social media for several weeks as the must see event in the City.

We created the effect by bouncing blue light off the water to light the underbelly of the deck, forming a blue zone above the water. Cool white light picks out the structural form and creates the sense of a floating wave hovering just above the deck.

On the deck we programmed the light to respond to the presence of people, to both guide them down the walkway and to signal the approach of oncomers. LED units that light the deck are triggered to change from blue to white as people pass, leaving a ‘comet’s trail’ of light in their wake.

We also took great care to carefully conceal the lighting equipment, positioning it within the handrail and mounting it on outriggers away from the bridge, to preserve the magic of the effect and to protect pedestrians from glare.
