Additional southbound lane restrictions for the Darlington Upgrade Project

Monday, 6 May 2019

The Department of Planning, Transport and Infrastructure (DPTI) advises motorists that lane restrictions for southbound traffic on Main South Road will be in place at the Darlington Upgrade Project for remediation works in the lowered motorway caused by recent rain.

Main South Road southbound between Sturt Road and Flinders Drive will be reduced to three lanes during peak periods, and two lanes during inter-peak. There will be no lane restrictions in place for northbound traffic on Main South Road.

This restriction is due to damage to a section of shotcrete (spray-on concrete) in the lowered motorway. It is anticipated that the restrictions will be in place for the next six weeks.

Motorists are advised to expect delays and to allow additional travel time. To ensure the safety of motorists and workers, please adhere to all lane restrictions and speed limits.

We thank motorists for their patience while these works are undertaken.
