View all latest news from the Southern Expressway project.

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.

Opening the Southern Expressway to two-way traffic is scheduled to occur in late July/early August 2014 – subject to weather conditions.

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.
