NSW Fire Commissioner Shane Fitzsimmons said “serious issues” remained across key roads after three major arterials in the state had reopened.
“I understand some highways have now reopened — the three key arterial roads have reopened,” he said on Sunday morning.
“We still have some serious issues along other key roads like the Kings Highway, which are continuing to be affected and closed as a result of these fires.
“While conditions have eased today, it is a good reminder that people need to remain vigilant and stay across what is going on.”
Mr Fitzsimmons urged holiday-makers to use their smartphones to stay up to date, and also monitor the NSW Live Traffic website.
As of 9.45am Sunday morning there were 24 roads closures due to bushfires across the state.
The Kings Highway from Braidwood to Nelligen remains closed in both directions. Araluen Rd from Moruya to Braidwood, while not impacted by fire, is close due to unsafe conditions and is not a suitable detour for the Kings Highway, authorities say.
Motorists can use the Snowy Mountains Hwy via Bega and Cooma as alternative routes.
In the Blue Mountains, the Great Western Highway yesterday reopened in both directions between Katoomba and Lithgow, but Bells Line of Road remains closed, restricting travel in and out of the area.
This morning, the Great Western Highway between Harley Ave and Victoria Palls Rd is heavily congested in both directions due to ongoing backburning operations.
Visitors have been told to avoid the Blue Mountains as Bells Line of Road between Coach House Road and Darling Causeway is closed in both directions, and Darling Causeway is inaccessible between Bells Line of Road and Station Street.
The Blue Mountains Botanic Gardens is also closed.
The Hume Motorway between Campbelltown and Sutton Forest reopened after being closed in both directions yesterday, and the Princes Highway from Falls Creek to Yatte Yattah has also reopened.
NSW Police assistant commissioner Karen Webb said earlier on Saturday the state’s residents should delay all non-essential travel.
“Delay your travel until tomorrow … conditions will be much milder and you can have a better trip,” Ms Webb told reporters.
Ms Webb later said commuters and travellers were “getting the message” to undertake essential travel only.
Fire danger was rated “catastrophic” on Saturday in the Greater Sydney, Illawarra-Shoalhaven and Southern Ranges regions and “extreme” in the Hunter, the ACT and the Central Ranges.
