A fiery truck crash has closed northbound lanes on the M1 Pacific Motorway at Mooney Mooney, north of Sydney, causing traffic chaos and queues up to 14 kilometres.
The accident between a B-double truck and mobile crane about 4am closed lanes just south of the Hawkesbury River bridge, with early-morning commuters advised they will remain closed for around four hours.
The two vehicles were both travelling north when the truck crashed into the back of the crane, with the jack-knifed B-double truck blocking all lanes between a cliff face and the median strip.
Fire fully engulfed the truck, sending thick plumes of smoke into the air and quickly spreading to nearby scrub.
The blaze has since been extinguished, however a large clean-up operation to clear debris, inspect the vehicles and check the road surface is underway.
Authorities are advising motorists to use the Pacific Highway from Wahroonga, adding the M1 will be closed for some time due to large amounts of debris.
School buses in the Berowra and Brooklyn areas are delayed up to hanf an hour.
NSW Police advised both drivers escaped serious injury, with one being treated at Gosford Hospital with minor injuries.
An unrelated multi-car crash on the M5 in Moorebank is also causing major delays for citybound commuters from Sydney’s south-west.
Early morning commuters are queued around eight kilometres onto the M7 and Hume Motorway, with motorists advised to allow plenty of extra travel time.
It’s believed around 11 cars were involved in the crash just before 6am.
