More than half of the Adelaide 500 track will need to be resurfaced before the supercar race in December and traffic disruptions are expected.
SA Motor Sport Board chief executive Mark Warren briefed the Adelaide City Council on Tuesday night about what work would need to be done to get ready for the race in less than six months.
"We've found the track surface in quite a dilapidated state," he told the meeting.
"A lot of the surfaces haven't been replaced since the grand prix days."
He said pit paddock in Victoria Park had "deteriorated beyond its design life" and had become unsafe and an "eyesore".
Mr Warren told the council that he wanted to extend the concreted part of the pit area.
Resurfacing will take place from the Britannia roundabout, down Wakefield Road, through Victoria Park and to the corner of Hutt Street and Bartels Road.
Work is set to start on August 1.
"I think there's going to be some minor road closures but a lot of the works are actually done overnight, and [we are] looking at how we might have some lane reductions and things like that, but generally it's well managed," Mr Warren said.
In the latest South Australian budget, the state government allocated $18 million to bring back Adelaide 500 in December, following through on a Labor election promise.
Victoria Park, which has been used as a major COVID testing drive-through site since 2020, will close on July 1 to make way for race preparations.
