Maintaining heavy vehicle access through work sites
Provide detours on infrastructure projects that affect heavy vehicle routes.
Infrastructure project teams must consider large and heavy vehicles when planning roadworks.
You must provide detours if your project affects access for any heavy vehicle that is operating:
- on Victoria's heavy vehicle networks
- via an NHVR permit.
View planned and unplanned disruptions as a layer on the national network map.
Detours can be:
- existing heavy vehicle network routes
- arterial roads outside the existing network (if we agree to this)
- local roads outside the existing network (if the relevant local council or other road manager agrees).
Planning resources
The flowchart below details best practice for maintaining access during roadworks, particularly for restricted access vehicles like B-doubles, cranes, over-size over-mass vehicles and vehicles operating under performance based standards.

It's intended for use by project teams, contractors, local government and agencies delivering infrastructure that limits or restricts heavy vehicle access.
It helps identify if and how roadworks might affect heavy vehicle access and the steps that need to be taken to formulate alternatives.
