A southbound lane of the M1 was closed for several hours on Tuesday after a potato truck caught on fire.
Fire and Rescue NSW said crews arrived to the motorway at Cooranbong near the Freemans Drive overpass about 3pm to find large amounts of black smoke and a truck that was "well alight".
Both southbound lanes were closed while Fire and Rescue and Rural Fire Service firefighters extinguished the flames.
One southbound lane remained closed until about 9pm while transport crews cleared the potatoes from the road.
