Southwark, London, England

The lights are programmed to correspond with the highs and lows of the pedestrian flow in the tunnel. During quiet times, there is a twinkling star effect, and in times of increased activity the firework effect builds up momentum, reaching a striking display climax.

The Clink Street tunnel project marks another success of the Light at the End of the Tunnel (LET) program. The program was launched to transform the 6 mile (10 km) stretch of disused Victorian viaducts south of the Thames River in Central London. This stretch consists of 97 roads and pedestrian tunnels, many of them dark and unwelcoming to pedestrians. The hope is that invigorating and unifying these areas with light will encourage investment, leading to jobs and other economic growth for the riverside communities.

"Southwark will become famous for the way it has transformed spaces that were previously dark and unattractive into bright and interesting routes for people to enjoy and walk through. Not only do the tunnel installations in many of the borough's historic railway arches enhance the original structures, they also provide a safer environment for pedestrians during the evening, "said Councillor Fiona Colley, cabinet member for regeneration at Southwark. "In addition to the sophisticated LED display fitted above pedestrians as they walk through this popular thoroughfare, Halo Lighting has also improved lighting along the footway, making it safer and more appealing for the public."
