46 overhead gantries are being installed on the West Gate Freeway, M80 Ring Road and Princes Freeway including interchange ramps. These gantries will hold information such as traffic signs or electronic signs that show the speed limit or lane closures. They will also eventually carry toll points as well, when the project becomes operational by 2025.
To install these gantries, there will be a number of overnight freeway closures of the West Gate or Princes freeways in one or both directions at a time to ensure they can be safely installed
Delays are expected.
