Infinity Bridge Stockton On Tees England

The Bridge as the shape of symbol infinity.

The Infinity Bridge is a public pedestrian and cycle footbridge across the River Tees in the borough of Stockton-on-Tees in the north east of England. It was built at a cost of £15 million. Its estimated design life is expected to be 120 years. The previous name of project was North Shore Footbridge but later it was named officially as INFINITY BRIDGE.
The name derives from the infinity symbol formed by the bridge and its reflection. The bridge is a dual, tied arch bridge or bowstring bridge. It has a pair of continuous, differently-sized structural steel arches with suspended precast concrete decking and one asymmetrically placed river pier. The tapering arches are fabricated from weathering steel plate box sections. The arches both bifurcate within the spans to form a double rib over the river pier.

Special Feature the Lights:
A special feature is made of the way the bridge is lit at night. This lighting scheme was designed by Speirs and Major Associates designers of the lighting for the Burj Al-Arab. At night the bridge handrail and footway are lit with custom made blue and white LED lighting built into the handrail that changes color as users cross. Attached to the steel cable ties are white metal-halide up-lighters to illuminate the white painted bridge arches, and blue LED down-lighters to illuminate the water and ground surfaces immediately below the deck. At night from certain viewing angles when the river surface is flat calm, the twin arches together with their reflection in the river appear as an infinity symbol ∞, and it is this effect that inspired its name.
