Road infrastructure in Canberra

Route numbers
The ACT generally does not number its highway and freeway grade roads; those that are numbered, are interstate highways and their connecting roads. The ACT has introduced the NSW alpha-numeric route system for these thoroughfares. The new system was implemented in 2013 at the same time as NSW completed its own transition to alphanumeric numbering.

Road hierarchy
The ACT classifies its roads into four groups, depending on its physical properties and role within the road network:

Arterial roads
These roads serve long distance travellers within or between districts, and support large volumes of traffic. They may be limited access, or controlled-access. A small number of these roads have relatively high levels of property access due to city design requirements at the time.

Major collector roads
These roads serve local area traffic distributing to or from minor collector roads, and also link to the arterial network. Well designed property access is permissible.

Minor collector roads
These roads serve neighbourhood traffic, and provide access from the major collector roads into residential areas. Normal direct property access is permissible at this level. Secondary links to the arterial network are possible.

Access streets
These streets are the lowest road type in the hierarchy, and provide access to the bulk of residential homes.

Controlled-access roads
Controlled-access roads in the ACT are often known as parkways either by name, or at some stage during their development, these generally (but not always) travel through peripheral areas between urbanised regions. *Partially limited-access

There are also memorial parks and rest areas along the route which honour Australia's Victoria Cross recipients.
