A three-kilometre stretch of the South Eastern Freeway at Monarto will be made safer after winning $340,000 in black spot funding.
The funding, approved by the federal government before the current election campaign, will be used to seal the road shoulder and install a wire rope barrier.
State Transport Minister Stephan Knoll and Liberal Member for Barker Tony Pasin visited the problem site, the scene of several accidents in the past, last week.
Mr Pasin is the chair of a consultative panel which allocates funding to black spots on South Australia's roads.
He said the government was committed to helping Australians get home safely from every journey they took on the nation's roads.
The federal and state governments are continuing to work towards a target of reducing road deaths and serious injuries by 30 per cent between 2011 and 2020.
A total of 103 people died and 932 were seriously injured on South Australian roads in 2011.
The number of serious injuries has reduced significantly since then - there have been 146 so far this year - but the road toll is currently on track to surpass the 2011 total.
