Westernport Water is upgrading the main drinking water and sewage pipeline, fixtures and fittings under the Phillip Island bridge.

The underbridge pipelines are a critical part of our region’s water infrastructure, supplying drinking water to customers on Phillip Island, and transporting wastewater from San Remo to the Cowes Wastewater Treatment Plant.

Works will take place between August 2023 and October 2024. Suspended scaffold will be used under the bridge so workers can safely access the pipes while minimising impacts to traffic.

Timeline

  • Under Bridge Pipe Inspection

    August, 2023

    Westernport Water conducted an inspection of the pipes underneath the Phillip Island Bridge as part of preparations for the San Remo Bridge Bracket Renewal Project. An Under Bridge Inspection Unit (UBIU) was used for the inspection.

  • Trial works

    • Proposed from mid until late November, 2023.
    • Access will be via standing scaffold at the San Remo end of the bridge.
    • Water and wastewater services will continue as normal while the works are occurring.
    • Cars will be able to cross the bridge as normal while works are occurring.
    • Pedestrian access across the bridge will remain open at all times, as will the pedestrian access track under the bridge at each abutment/end.
  • Main works

    • From 15 January 2024 until October, 2024
    • Suspended scaffold will be used under the bridge so workers can safely access the pipes while minimising impacts to traffic.
    • Water and wastewater services will continue as normal while the works are occurring.
    • Marine users can expect some changes to clearance and navigation under the bridge while the works are happening. A middle section of the bridge will remain clear of scaffolding at all times to ensure tall marine vessels have full clearance under the bridge.
    • Heavy vehicle operators are subject to General Mass Limits (GML). A GML of 43ton applies to semi-trailers and a GML of 63ton applies to B-Doubles.
    • Cars will be able to cross the bridge as normal while works are occurring. On rare occasions, one lane of the bridge may need to be closed while scaffolding is being installed and relocated. This will happen at night to minimise disruptions to traffic.
    • Pedestrian access across the bridge will remain open at all times, as will the pedestrian access track under the bridge at each abutment/end.
