A four-stage $3.05 million road resurfacing project along Victor Harbor Road began this week, with an estimated completion date of mid 2021.
The project will target four separate sections of road between Willunga and Mount Compass and involves spray-seal and asphalt resurfacing.
Works on two sections of road at Willunga Hill and south of Yundi Road totalling 1.7 kilometres began on Wednesday, March 10.
Stage three works between Lanacoona Road and Sand Mine Road will begin on Sunday, March 14, while works on the final section at Mount Compass are expected to start in early April.
The project is being jointly funded by the Australian and South Australian governments on an 80:20 split and Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development Michael McCormack said the federal government was investing in the works to deliver a smoother and safer road network for drivers in the region.
"This is what the Australian Government's $110 billion infrastructure investment pipeline is all about - getting Australians home sooner and safer while boosting local economies as we bounce back from the COVID-19 pandemic," Mr McCormack said.
Two sections of works will be undertaken at night, while the remaining two will be carried out during the day and traffic delays are expected.
Victor Harbor Road will remain open to traffic, however speed restrictions and traffic management will be in place and traffic will be required to stop at times.
South Australian Minister for Infrastructure and Transport Corey Wingard said a $16.7 billion infrastructure investment by the state government would ensure the safety and quality of regional roads.
"This $3.05 million project forms part of the jointly funded $52 million Regional Road Network Package, which is delivering pavement treatments, shoulder sealing and safety enhancements to benefit the freight industry and regional communities across the state," Mr Wingard said.
Senator for South Australia Andrew McLachlan also welcomed the funding as a win for the region and thanked road users for their patience.
The works are expected to be completed in mid-2021, weather permitting.
