NT Legislation specifies maximum dimensional and mass limits for vehicles which may travel on public roads in the Northern Territory.
These limits are necessary to enhance the free flow of traffic to control damage of the infrastructure and to promote the safety of all road users.
The NT Legislation does recognise the possibility that sound reason may exist for allowing vehicles and loads that exceed these limits to operate on all or part of the road system by permitting exemptions to be granted.
As of 5th January 2015 the next stage of construction works will begin to progress the duplication of Tiger Brennan Drive. A guard rail will be constructed to the left of the West-bound (inbound to Darwin CBD) lane of Tiger Brennan Drive. The guard rail will run the length of Tiger Brennan Drive from the Berrimah Road intersection to the Woolner Road intersection and is expected to be in place for a minimum of 18 months. For more details regarding the project please visit the Department of Infrastructure’s projects website at www.nt.gov.au/infrastructure/projects/index.shtml
The installation of the guard rail will result in a corridor restricting the safe movement of any wide loads over 4.0m. This route will be closed to all wide loads exceeding 4.0m in width. If an alternate route is not available for a proposed load, approval must be sought from the Department of Infrastructure via the usual permit application process (form VS6).
Notification of the restriction will be published on the NT Road Report website at www.ntlis.nt.gov.au/roadreport.
On-site signage will also warn drivers of the restriction.
