Illuminated River is a large-scale public art commission which lights up nine bridges in central London across the River Thames. Designed by American artist Leo Villareal in collaboration with British architects Lifschutz Davidson Sandilands, it uses LED light fittings to produce sequenced patterns of moving light across the bridge structures. At 3.2 miles (5.1 km) in length, it is one of the world’s longest ever public art commissions. The first phase – Southwark Bridge, Millennium Bridge, London Bridge and Cannon Street Bridge – was launched on 17 July 2019. It was completed in April 2021 with the illumination of Blackfriars Bridge, Waterloo Bridge, Golden Jubilee Footbridges, Westminster Bridge and Lambeth Bridge. The installation has a minimum lifespan of 10 years. (en)
