Weekend Works – Marion Road entry ramp and Panalatinga exit ramp

Weekend works will be undertaken at the entry ramp at Marion Road Interchange, Sturt and the exit ramp at Panalatinga Interchange, Reynella, to undertake the asphalt works for the Southern Expressway Duplication project.

The works will be undertaken on Saturday, 30 August and Sunday, 31 August 2014 between the hours of 7.00 am and 7.00 pm.

The expressway will remain open except for the southbound entry ramp at Marion Road and the exit ramp at Panalatinga Interchange, which will be closed for the weekend duration.

Signage will be in place to alert motorists of the changes to traffic conditions and speed restrictions will be in place

Southern Expressway open to two-way traffic

The Southern Expressway opened to two-way traffic on Sunday 3 August 2014.

Works after opening to two-way traffic

Some construction activities will continue including interchange ramp road works, activation of the new two-way electronic signage system, landscaping, fencing, construction of the new western recreational pathway and noise barrier installation.

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.

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.
