SA’s most dangerous roads list reinforces RAA’s call for highway upgrades

24 March, 2023

New data has revealed South Australia’ most dangerous roads, with several highways that have been identified by RAA as priorities for upgrades making the list.

SA Police figures show August Highway was the state’s most deadly road over the last five years, with 44 fatalities recorded. Next on the list was Sturt Highway with 36, followed by Princes Highway (22) and Dukes Highway (19).

The most dangerous metropolitan road was Main North Road (17).

RAA Senior Manager Safety ad Infrastructure Charles Mountain said RAA’s most recent election priorities included completing the duplication  of the Augusta Highway, together with a program to also duplicate the Sturt Highway and Dukes Highway, which would substantially improve safety on these roads.

“This new data confirms RAA’s position that there are highways in South Australia that are yet to be duplicated and are posing the most danger to motorists.

“RAA believes a long-term commitment to fully duplicate the Augusta, Dukes and Sturt Highway will greatly improve road safety outcomes on these corridors, particularly as over 30% of all vehicles using these routes are heavy commercial vehicles, including road trains.

August Highway, South Australia’s most dangerous road

“The Augusta Highway, for example, is the principal route to the north of the state for freight, agriculture and tourism, carrying more than 4,000 vehicles per day.

“Historically this road has accounted for more than 5 per cent of lives lost on South Australian roads.

“RAA welcomes the State Government’s commitment to duplicate this corridor and supports the investment to date, including $124.5m for the overpass at Port Wakefield.

“But it needs to be fully duplicated as quickly as possible.

“Duplicating these roads would also support economic recovery and enhance freight productivity in our regions.”
