A burst water main at the intersection of Greenhill and Unley Roads last night is still causing problems in Parkside.
Commuters faced major delays last night and this morning following the burst around 5.30pm when parts of the road sank.
Crews have been working through the night to repair what's believed to be a 50 year old pipe.
Pressure's been shut-off to homes and businesses close-by while some traffic lights are out.
It was thought that water would be back on by midday but crews are still conducting works.
