The $407.5 million duplication of the Southern Expressway will deliver an 18.5 kilometre multi-lane, two-way expressway between Bedford Park and Old Noarlunga. It is a key part of creating a free-flow north-south corridor and will provide people living in Adelaide’s south with improved access to employment, education, shopping and community facilities.

The duplication will put Adelaide’s southern beaches and the McLaren Vale wine region within easier reach and make getting to and from the Fleurieu Peninsula easier, likewise Kangaroo Island.

This project will also support economic activity in Adelaide’s southern commercial and industrial areas like Reynella, Lonsdale and Noarlunga Centre as well as help the state achieve identified targets in the South Australia Strategic Plan.
