The $407.5 million duplication of the Southern Expressway is a key part of the development of Adelaide's north-south corridor and, when complete, will deliver an 18.5 kilometre multi-lane, two-way expressway between Bedford Park and Old Noarlunga by mid-2014.

This will provide people living in Adelaide’s south with improved access to employment, education, shopping and community facilities and will put Adelaide’s southern beaches and the McLaren Vale wine region within easier reach.

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.
