Location: We closed CityLink in both directions between Footscray Road and the West Gate Freeway, including the Bolte Bridge.
Timeframe: Sunday 5 May 2024, 6:00am - 11:00am.
What did we do?
In a unique intersection of aviation and energy expertise, we successfully removed four redundant aircraft warning marker balls from the overhead transmission lines next to the Bolte Bridge.
The marker balls, each measuring one metre in diameter and weighing two to five kilograms, were originally installed in 1997 to aid Police Air Wing navigation.
After being bolted to the transmission lines for over 27 years, these marker balls are no longer required and due to their age were removed for the ongoing safety of motorists and the community.
This complex operation saw us team up with our trusted delivery partner, Zinfra Power Services, with a linesworker in a specialist helicopter navigating the cityscape to remove the devices. This required careful handling given their size and high altitude, not to mention nerves of steel!
