While Tasmania's highway network has been constructed to a high standard, its grade-separated freeway network is limited. In the past, Hobart and Launceston have each had comprehensive transport studies conducted, proposing grade-separated freeways running through and around them. While some of these roads have been constructed, the majority are limited access featuring at-grade intersections. Devonport and Burnie are the only major population centres with freeway standard roads linking each other. There have been repeated proposals in recent years to fully upgrade the Midland Highway to grade-separated freeway standard.^[8][9]
This List is limited to Tasmania's freeway-standard roads.

• Brooker Highway (Rosetta to Granton)
• Midland Highway (Brighton Bypass)

• Tasman Highway (Tasman Bridge to Hobart Airport)

• Southern Outlet (Hobart to Kingston)

• Channel Highway (Kingston Bypass)

• Bass Highway (Burnie to Devonport and Prospect to Illawarra Main Road)
• Midland Highway (South Launceston to Breadalbane)

Victoria has the second largest number (behind New South Wales) and highest density of freeways in Australia, with the majority being located in Melbourne City or the metropolitan areas. While most of Australia has a low population density over a large area, where towns are sparse or located a significant distance from each other; Victoria has towns located throughout the entire state, with large numbers of inhabitants, in both urban and rural areas (many of which are major) such as Ballarat or Bendigo. In addition to the roads listed below, Victoria has a number of dual carriageway standard Highways that are given an "M" designation.
