Dubai's Roads and Transport Authority (RTA) has upgraded 39 tunnels and road crossings around Dubai.
Traditional lights at the tunnels and road crossings have been replaced with 14,400 eco-friendly LED lights over the course of six months.
Some of the tunnels that have been upgraded include the Airport Tunnel, Shindagha Tunnel, Dubai Mall Tunnel and the Dubai World Trade Centre Tunnel.
The LED lights consume 60% less energy when compared to the previous lighting fixtures used, and have a life span of 50,000 hours.
Maitha bin Adai, CEO of Traffic and Roads Agency at RTA said, "RTA carefully evaluated the level of brightness and colour clarity inside Dubai's tunnels when installing the new lighting units to ensure optimal visibility for road users, consequently enhancing traffic safety. The LED lighting units offer a lighting intensity of 6000 lumens compared to 4000 lumens for older lamps, improving the lighting quality. These units do not include environmentally harmful chemicals, like mercury found in traditional lights, which serves RTA and Dubai's vision of achieving environmental sustainability."
