Plenty of jobs don't stop at a boundary. A trench runs from a local road onto a state highway. A resurfacing job sits on a road that two councils share. A traffic management layout on a council street needs to extend onto the highway it joins. Historically that meant two applications, two sets of attachments and keeping two approvals in step.
One worksite, more than one road authority
When both road authorities are on myWorksites, you create the worksite once and add the second authority to it. The application, the extent and the documents flow through to both. You don't download an approved copy from one system to upload it somewhere else, and you can see where each authority is up to in the same place.
With the entire state highway network on myWorksites, this covers any job that touches a state highway as well as one that crosses between councils already on the platform.
What still differs
Each road authority makes its own decision about its own network. Lead times, conditions, fees, peak-hour restrictions and local operating procedures can all be different on either side of the boundary. Check each authority's guidance, allow for the longer of the two lead times, and expect conditions from both.
Your traffic management plan needs to work across the whole site, including the transition from one road to the other. A layout that suits a 50 km/h local street may not suit the highway it joins.
When one of them isn't on myWorksites
If the other road authority uses a different system, you'll still need to apply to them separately. You can check which councils are on myWorksites on our councils page. If yours isn't, tell us where you're working. It helps us understand where contractors are being asked to use two systems.
