SUPERCARS racegoers have been warned to plan ahead and travel safely ahead of the motorsport event's return to Newcastle streets from Friday.
Police said on Wednesday large crowds are expected and a high-visibility operation will run across the three days.
The Newcastle 500 was last held in 2019, but crowds are expected to remain significant.
Newcastle Airport estimates more than 5000 additional passengers will fly through its halls this week ahead of the season opener, with additional flights running to meet the demand.
"Over 4500 additional seats have been made available through Newcastle Airport with Virgin Australia between Newcastle and Brisbane and Melbourne on top of our normal schedule of over 13 flights," Airport chief executive Dr Peter Cock said.
"More flights and more visitors to our region has far-reaching benefits on the local economy."
Three of those extra flights link with Brisbane, with the remaining 10 Melbourne connections.
The airport's highest ever passenger throughout came the day before the first Newcastle 500 in 2018, a record the airport hopes will tumble this week.
Officers from Newcastle City police district and across the Northern Region will focus on road safety, anti-social behaviour and alcohol-related violence.
Specialist police will also offer assistance to general duties officers.
Northern Region commander Assistant Commissioner Peter McKenna said the event was a highlight for the city that drew thousands of spectators, but warned all to keep the peace.
"Our number one priority throughout Operation NEWCASTLE 500 2023 is to ensure everyone has the opportunity to safely enjoy their time at the event," Assistant Commissioner McKenna said.
"Racegoers and local residents are reminded there are several road closures and diversions throughout the Newcastle CBD, and a number of special event clearways and bus zones are in place.
"Motorists are urged to allow extra travel time and expect heavy traffic and delays on local roads, particularly around times when crowds are arriving at or leaving the event.
Assistant Commissioner McKenna also reminded patrons that Supercars tickets include public transport, urging to take advantage of that to reduce congestion.
Transport for NSW executive director of customer coordination Roger Weeks said major changes would abound until the event was over.
Ferries will operate, with extra buses on routes 11, 13 and 14. Light rail passengers are advised to exit at Queens Wharf during the race.
Trains between Scone, Singleton, Dungog and Maitland will be replaced with coaches on the weekend to allow for more frequent services between Maitland and Newcastle.
"There will be significant road closures and clearways throughout the Newcastle CBD until Monday, and it is best to avoid driving around the city," Mr Weeks said.
"Motorists should consider parking at the commuter carparks at key stations along the Central Coast and Newcastle Line - including Wyong, Morisset and Fassifern - then continue to Newcastle by train.
"Unlike the 2019 Newcastle 500, a park and ride option from Broadmeadow (McDonald Jones Stadium) to the circuit will not be available this year."
Traffic and Highway Patrol commander Assistant Commissioner Brett McFadden APM said speeding, drink and drug driving, and distracted driving remain the biggest killers on our roads despite their preventable natures.
"Police won't tolerate anyone breaking the law through dangerous driving, this includes speeding, drink and drug driving, or driving while distracted," Assistant Commissioner McFadden said.
