Thorn Lighting has illuminated the Queensferry Crossing – an impressive new bridge spanning the Firth of Forth on the eastern side of Scotland. A selection of Thorn luminaires has been chosen to illuminate the imposing structure, creating a striking stream of light that stretches across the Forth Estuary. 
     With a length of 2.7 kilometres, the Queensferry Crossing is the longest three-tower cable-stayed bridge in the world. The towers, each more than 200 metres high, are connected to the roadway by 37,000 kilometres of cabling - almost enough to go around the earth. The structure is positioned upstream from the famous Forth Railway Bridge and is expected to serve around 24 million vehicles each year. 
     The lighting scheme was developed to enhance the strong aesthetics of the bridge and ensure excellent energy efficiency. The lighting technologies and luminaires were carefully selected to fulfil various specific functions, utilising lenses and precise focusing to maximise effectiveness and minimise stray light and glare. 
     Altis floodlights illuminate the towers and highlight the distinctive shape of the bridge at night. This high-performance fitting incorporates a patented optic that offers a unique range of photometry, including outstanding levels of vertical illuminance that accentuate the north, south and central towers. Excellent thermal management and IP65 protection help maintain a consistent and stable light output.
