Temporary 42.5 tonne vehicle mass limit for San Remo / Phillip Island Bridge

A temporary 42.5 tonne vehicle mass limit will be in place for the San Remo / Phillip Island Bridge from 1 July 2024 until late September 2024 as part of Westernport Water’s Pipeline Bracket Renewal project.

The project will refurbish the main drinking water and sewage infrastructure connected to the underside of the bridge.  Scaffolding needs to be suspended under the bridge so workers can safely access the pipes while minimising impacts to traffic and pedestrians.

The 42.5 tonne vehicle mass limit is needed while the scaffolding is installed for the three central spans of the bridge.

Vehicles weighing 42.5 tonne or below will be able to access the bridge as normal. Trucks that are used to supply groceries, household goods, petrol, and events at the Phillip Island Grand Prix Circuit will not be affected as they typically carry loads of 42.5 tonnes or below.

Mass limits also apply for certain heavy vehicle types outside the 1 July to late September period, until December 2024.

Heavy vehicle operators are advised to visit Westernport Water’s website or the National Heavy Vehicle Regulator’s National Network Map for up-to-date information on network access and mass limits before they commence their journey.

“To lessen impacts to the local economy, the mass limit of 42.5 tonnes will be in place over winter when construction projects typically ease.”

“The freight industry has been provided with sufficient forward notice of the temporary mass limit reduction, allowing them time to plan ahead and adjust their operations accordingly.”
