Road Safety Program

We're delivering critical road safety upgrades and improvements on remote, regional, urban roads, footpaths and cycle paths around South Australia. The $168 million program is jointly funded by the Australian (50%) and South Australian (50%) governments over three years.

These upgrades will support:

improvements to freight movements
regional economic growth
improved safety for all road users.

Minor projects and resurfacing

Under the Road Safety Program, we did some minor resurfacing projects. Works include shoulder sealing and shoulder widening to:

provide a greater sealed road width
allow more opportunity for a vehicle to recover safely if it moves from the travelling lane.

Works along Black Road, between Main South Road and the Happy Valley roundabout were completed in May 2025.
