CityLink is a 22-kilometre motorway. Most of the motorway is eight lanes wide, with four inbound and four outbound lanes.

The Bolte Bridge and the Burnley and Domain tunnels are all part of CityLink. CityLink connects Melbourne’s Monash, West Gate, and Tullamarine freeways.

It also connects the city centre with Melbourne’s major airport and port. The average daily volume of traffic of light vehicles on CityLink is over 800,000.

The contract was awarded to Vitronic Australia in October 2020 by CityLink Motorway Limited, a wholly owned subsidiary of the Transurban Group.

The project involved upgrading the CityLink Roadside System, with the new Vitronic solution replacing video camera systems and tag reader technology modules.

The new upgraded solution from Vitronic was successfully deployed on all 17 toll points and proceeded into live operation in September 2023 with the project reaching completion in May 2024.
