There will be no public toilets as part of the new heavy vehicle rest area costing $3.8m on the Princes Highway at Salt Creek.
There have been no such facilities since the Salt Creek Roadhouse closed six years ago.
The toilets were accessed by the public but cleaned and maintained by the roadhouse proprietor at his expense.
The heavy vehicle rest area was announced as part of the 2024/25 State Budget.
Liberal frontbencher Adrian Pederick asked Transport Minister Tom Koutsantonis in parliament what amenities will be included at the new heavy vehicle rest area at Salt Creek.
In reply, Minister Koutsantonis expected there would be a rest area with seating, canopy, table and a bin.
“Are there going to be bathroom and toilet facilities built there, considering its location?” Mr Pederick asked.
“No,” the minister said.
Travellers will continue to travel the 143km between Kingston and Meningie without toilets.
