Find out about the state road network in South Australia.
State road network
The state government through the Department for Infrastructure and Transport manages around 25% of South Australia's total road network, including:
- 13,000 kilometres of sealed roads
- 10,000 kilometres of unsealed roads.
Local government is responsible for maintaining 75,000 kilometres of local roads.
How traffic on state roads is monitored
Traffic volume figures estimate the number of vehicles on roads maintained by the state government. They are used to help manage, maintain and improve the traffic network. The two main measures are:
- annual average daily traffic estimates
- commercial (heavy) vehicle estimates.
Estimates of traffic volumes for metropolitan roads and rural roads are available as a series of maps.

Transport corridors
Transport corridors managed by the state government, including public transport, freight, bicycle, pedestrian and car movements, have an important role in achieving the state's goals.
The draft document A Functional Hierarchy for South Australia's Land Transport Network (9.3 MB PDF) guides the use of all transport corridors for which the state government is responsible.
