A street party at Tailem Bend will open next month's second running of the OTR Super Sprint at The Bend Motorsport Park.
Race cars and their drivers, vintage vehicles, food and merchandise stalls, music and a kids' zone will fill Railway Terrace on the Thursday afternoon and evening before racing starts on Friday, August 23.
The Coorong council estimated the celebration would draw about 1000 or more visitors into the town and, with any luck, entice them to spend more of their money at local businesses.
The event will be managed by Tailem Bend RSL.
Meanwhile, the Big Four holiday park at the race track, completed in December, is already fully booked for the Super Sprint and will accommodate more than 1400 Supercars fans.
Another 600 are expected to camp along the track, many more will fill the Rydges Pit Lane Hotel, and thousands more will commute from Adelaide or elsewhere for one or more of the event's racing days.
As they arrive and leave, at least one extra entrance and exit will be in operation to help avoid a repeat of last year's traffic jams, while more parking attendents will be employed and an extra, temporary, turning lane will be provided for vehicles attempting to get onto the Dukes Highway.
The race venue itself has also been upgraded since year one.
More than 3000 trees have been planted across its previously dusty expanse.
A new, permanent grandstand is also being built on pit lane, replacing a temporary structure brought in for the 2018 race.
The Bend Motorsport Park's managing director, Sam Shahin, said he had received a lot of feedback from people who attended the inaugural Super Sprint.
"We have been working hard to make sure that year two is bigger and better," he said.
"The venue is constantly evolving, and we are looking forward to providing another first-class experience for visitors.
"Our internal circuit shuttle will allow fans to jump on and off at different stops; and, due to the popularity of 'park and view', we've also increased the capacity and split it into two zones.
"Seeing cars parked and campers lining the circuit ... so close to the action creates such a unique atmosphere."
The event had already been advertised by race organisers before it was formally approved by the Coorong council last week.
