Tasmania Higher Mass Limits (HML) Approved Network

Shows roads in 3 categories: approved (green), conditionally approved (orange) and restricted (red). Tasmania's HML network does not allow access for: (1) Truck and dog trailer combinations - this is provided via the Increased Mass Limit (IML) network. (2) Approved Performance-Based Standards (PBS) combinations unless the road also appears on the applicable PBS network for the combination, in which case the Tier 1 Bridge assessment HML masses are applicable. (3) B-doubles that exceed 21m unless the road also appears on the 23m or 26m B-double network map.
