New overtaking lanes to improve safety on Horrocks Highway

Wednesday, 14 June 2023

The construction of two new overtaking lanes is the latest step in the Horrocks Highway upgrade project, delivering safer journeys along the key freight route.

One overtaking lane is now open in each direction southbound and northbound just south of Tarlee, with all speed and lane restrictions removed.

The final layer of asphalt has been laid and line marking completed, after some areas of the new lanes were identified as in need of remediation during construction.

Improvements to the Horrocks Highway are jointly funded by the Australian and South Australian governments on an 80:20 basis.

The package of works is delivering infrastructure upgrades along the 245-kilometre section between Wilmington and Gawler to improve safety, connectivity and freight efficiency, while also supporting jobs.

Works include shoulder sealing, pavement rehabilitation, lane widening, sealing of local road approaches, new overtaking lanes and overtaking lane extensions, bridge upgrades, safety barrier, audio tactile line marking on edge-lines and centrelines, and improvements to the Gladstone rail corridor and level crossing.
