ROAD CLOSURE PROCEDURES IN SYDNEY
To minimize traffic jams in the city center and on major roads out of Sydney, the City's highway department will not agree to road closures scheduled for weekdays or Saturdays. On minor roads outside the city center, weekdays and Saturdays may be considered. You must apply for approval to do roadwork and other road-related activities, tree cutting and use of very large construction machinery, ladders, etc. Please note that approval is needed if you plan to block the road or footpath.
Applications to have a road closed to traffic must be completed and sent to the Department's Traffic Calming Committee at least a month before the scheduled date.
Roads can be closed partially or fully, depending on your requirements. Partial road closures are only allowed in light traffic areas where there will be at least 1 lane for traffic with extra traffic control measures to make sure 2-way traffic can continue to run for the duration of the work. Any change of traffic flow will require the proposal to be treated as a full road closure. For further information about a partial road closure, please refer to Contacts.
If you are organizing a parade, march or other type of street-based event, approval is also required and we recommend you choose one of our 4 preferred routes. Choosing an existing route reduces the amount of planning you will need to do.
