Southern Expressway Duplication

The $407.5 million duplication of the Southern Expressway is a key part of the development of Adelaide's North-South Corridor. It’s  an 18.5 kilometre multi-lane, two-way expressway between Bedford Park and Old Noarlunga.

Key benefits

This expressway:

• gives people living in Adelaide’s south improved access to employment, education, shopping and community facilities
• puts Adelaide’s southern beaches and the McLaren Vale wine region in easier reach
• supports economic activity in Adelaide’s southern commercial and industrial areas like Reynella, Lonsdale and Noarlunga Centre
• helps the state achieve identified targets in the South Australia Strategic Plan.
