A major road in northern Sydney remains closed after a fiery tanker crash on Tuesday that claimed two lives.
Crews worked overnight to clean up debris left behind after a fuel tanker crashed and exploded at Mona Vale on Tuesday afternoon.
AAP reports Mona Vale Road remained closed in both directions between Pittwater and Powder Works roads on Wednesday morning and there was no indication when it will reopen.
Motorists were advised to use Pittwater Road, Wakehurst Parkway and Forest Way instead.
Police said it appears the truck lost control, hit a powerpole and four other cars before ending up on its side, spilling fuel over the road.
Two men in one of the cars died in the blaze just after 3pm on Tuesday and six other people were taken to hospital.
AAP reports the cause of the accident is not yet known.
"At this stage what we do know is the tanker was driving east on Mona Vale Road and it appears to have lost control," Acting Superintendent Mark Cook told ABC Radio.
He said it appears the men's deaths were due to the explosion rather than the collision.
