The Bolte Bridge, built in 1999, spans Melbourne’s Yarra River. Named after Sir Henry Bolte, the former Premier of Victoria, it features two 140m high silver towers situated on either side of the road at the midpoint of the bridge’s span.
Pharos partner ULA was invited to design and supply a lighting solution to revolutionise the iconic towers of the Bolte Bridge. It was an opportunity to both enhance the lighting and to meet stringent Australian sustainability energy reduction targets.
Pharos LPC Controllers transmits a DMX signal from one of the towers via a Lumen Radio Flex outdoor transmitter and receiver to dynamically colour-change all seventeen Griven LED exterior wash luminaires. These replaced the old halide lights and were installed on newly erected platforms at the base of each bridge tower to achieve even coverage and maximum light output.
By bathing this Melbournian landmark in different hues, the system can be used to support and involve the bridge in special cultural and sporting events. Energy usage was reduced by an incredible 89% after the new lighting scheme was installed.
