A new arts project in Glasgow will see one of the busiest road bridges in Europe bathed in light, which will pulsate in time with the traffic.
The Kingston Bridge will be bathed in light
Lighting fixtures on the banks of the River Clyde will project colour onto the underside of the Kingston Bridge.
The £300,000 project, funded by Glasgow City Council, is the work of New York artist Leni Schwendinger and Scots architect Ian Alexander.
The lighting sequence, beginning on Monday, is linked to traffic levels.
The city began its lighting strategy in 2002 and has allocated more than £5m up to 2007.
The Kingston Bridge switch on takes place at 1030 BST.
Prominent buildings that have been lit up include the Gallery of Modern Art, the Glasgow Royal Concert Hall, City Chambers, St George's Tron Church, Tollbooth Steeple at Glasgow Cross and Anniesland Tower.
On the Clyde, George V Bridge, Glasgow Weir, Victoria Bridge and Glasgow Bridge are illuminated.
The Mitchell Library and the Kelvingrove Art Gallery and Museum are due to be lit up in the next year.
The Kingston Bridge opened to traffic in June 1970 and now carries more than 180,000 vehicles per day across the river.
Mr Alexander, of JM Architects, said: "It is our hope that the lighting for the bridge will reveal the heroic qualities of this structure and allow onlookers to reappraise such a significant structure in the centre of Glasgow."
Leni Schwendinger said: "Two concrete structural arcs make up the Kingston Bridge. This canvas consists of the bridge's grand concrete swaths; the underside and two inward faces that connect the arcs.
"My refined palette selection and highly orchestrated programming allows for 144 sequences of unique colour mixes - which will be linked to the actual traffic patterns as data flows through sensors to the lighting control board."
Baillie Allan Stewart, convener of Glasgow City Council's Lighting Strategy (Policy & Resources) Working Group, said: "It is part of the council's wider commitment to our lighting strategy which highlights some of our best architectural assets and at the same time ensures a safer, brighter street environment for our citizens."
