A FIERY crash between a B-double truck and a mobile crane is blocking all northbound lanes on the M1 Pacific Motorway at Brooklyn, north of Sydney.

The two drivers escaped serious injuries in the accident at 4am on the motorway about 2km south of the Hawkesbury river.

Both vehicles were travelling north when they collided.
 

But their badly damaged vehicles are still blocking all lanes between the cliff face and median strip.

The accident also caused a scrub fire on the median strip which has now been extinguished.

One driver was taken to Gosford Hospital with minor injuries, while the second driver miraculously escaped unharmed.
