Updated access for 35 metre Modular B-triple, Lachlan Valley Way
Published today 24 June 2026, in line with the above, is an update to the 35 metre Modular B-triple access on Lachlan Valley Way from the Hume Highway near Yass to Wongajong Road, Forbes.
This temporary emergency access has been approved as part of the National Fuel Security Plan. This will also assist to ease productivity burden for freight movement between the Central West and Sydney due to the Great Western Highway closure.
We strongly recommend all operators review the updated National Network Map in detail for any conditions that may apply to road segments and/or structures but wish to draw particular attention to the following restriction:
There will be no changes to axle mass limits or gross combination mass limits for these higher productivity vehicles or existing heavy vehicles. Productivity improvements are achieved by enabling appropriate vehicle configurations to carry more freight per trip, rather than increasing vehicle weight.
TfNSW are continuing to investigate options to enable greater access for higher productivity vehicles and will provide more information on future changes as assessments are completed.
TfNSW is working with the NHVR to develop and publish a separate Notice for access moving forward, however an amendment has been made to the existing 35 metre Modular B-triple network in the interest of time.
During this fuel response, heavy vehicle safety and compliance will be critical. To ensure road safety and infrastructure protection outcomes are maintained,
Transport for NSW will use network-based monitoring equipment and partner with the National Heavy Vehicle Regulator through on-road and off-road compliance activities.
