Heavy holiday traffic is being affected by a car fire on the Kings Highway and a crash on Mount Ousley, north of Wollongong.
The car fire was reported at Manar, near the Goulburn Road turnoff, between Braidwood and Bungendore, shortly after 1 pm on Monday 1 April 2024.
Emergency services are attending and have advised motorists to take extra caution and allow extra travel time.
Police are directing traffic on site.
The incident happened as traffic began to build for the trip home after the four-day Easter holiday weekend.
Perfect autumn weather boosted the number of holiday-makers enjoying the coast but is likely to contribute to a long trip home for many.
Significant delays are also predicted through Milton/Ulladulla, and a two-car crash at New Mount Pleasant Road on Mount Ousley has also closed a northbound lane.
Authorities are urging motorists to plan their journey and to show extra patience at peak travel times.
