The duplication of Main South Road between Seaford and Sellicks Beach aims to improve road safety, as well as improve traffic flow and increase capacity.
The duplication will be delivered in two stages.
- Stage One will involve the duplication of approximately 10 kilometres of Main South Road from south of Griffiths Drive in Seaford to Aldinga. This will include the duplication of the Pedler Creek Bridge at Seaford Rise.
- Stage Two will include a ‘2+1’ lane road layout for approximately six kilometres from Aldinga to Sellicks Beach.
The Government of South Australia will also duplicate Victor Harbor Road, between Main South Road and the McLaren Vale turn off.
