Tasmanian declared Higher Mass Limit (HML) network
This network shows roads mapped in three categories: Approved (green), Conditionally Approved (orange) and Restricted (red). Click on a route or bridge to show any conditions that apply. Tasmania's HML network does not allow access for:
Restricted structures (red dots) must not be crossed.
Roads not shown as approved (green) or conditionally approved (orange) require road manager approval for access by permit. Application for access by permit is to be made through the NHVR. It is permitted to travel off route if the road is marked with detour signage or if directed by an authorised officer.
Operators must check for road closures and road conditions prior to travel to ensure clear passage. For roads managed by Department of State Growth this information is available on the Department of State Growth website and by selecting the “show state growth road works” button on this map.
