Beyond Purple Haze: light show on Zagreb’s Hendrix bridge triggered by trains

Philips Lighting has given Zagreb’s Hendrix bridge a unique lighting makeover with a spectacular LED light show that is triggered by trains passing over it.

The 300m-long Zeleni Most (Green Bridge) carries the railway over the River Sava in the Croatian capital. Most people in the country simply know it as the ‘Hendrix bridge’ ever since graffiti with his name appeared on the bridge in 1995.

At night the bridge is bathed in an almost ethereal white light showing off its arch, spans and graceful design. However, as a train approaches, it is detected by a sensor and the white light fades to black causing the bridge to seemingly disappear. Then, as the first coach behind the locomotive crosses the bridge, coloured lights come on in sync with the speed of the train crossing the bridge. Both the bridge and train are bathed in a moving ribbon of colour worthy of a riff from the bridge’s namesake. As the train disappears the white light returns.

Dean Skira noted that the bridge itself provided the starting point for the design. “Most bridges are utilitarian in appearance; few of them possess the architectural or structural ingredients required to be able to use light as a medium to enhance the beauty of the engineering. What we created with Philips Lighting was something very special.”

The revitalised railway bridge makes the surrounding area more attractive for locals and visitors. “The goal was to upgrade the visual identity of the City of Zagreb. It is part of our plan to enhance city life around the Sava river,” said Ivan Babic, Head of the Infrastructural Services Department for the city. “The innovative LED lighting highlights the grandeur, colour and the beauty of the bridge. It’s become a tourist attraction with people often stopping to take pictures in front of it.”
