Queen Elizabeth II Metro Bridge, River Tyne
Nocturne is a permanent light and colour installation built into the fabric of the QEII Metro Bridge between Newcastle and Gateshead.
Visible from many places in and around the Tyne gorge, the work has two elements. By day the two-tone colour pattern on the 360-metre bridge changes its aspect according to the angle from which it is viewed and the time of day. At night led light units create a subtle pattern of colours which changes with the rise and fall of the tides below.
The lights never repeat the same combination of colours twice as pre-programmed barcodes of colour ripple across the structure, rising and falling in brightness and intensity to match the ebb and flow of the tide.
