A petrol station in Fontwell remained closed today after being engulfed by a blaze.
The Shell business just off the A27 is set to be shut for some time after the fire on Monday.
No-one was injured by the fire but nearby premises were evacuated by the police as a precaution.
Eyewitness Jason Green, who lives in Arundel Road, in close proximity to the garage, said: “My family and I were just finishing breakfast when we heard a small bang.
“I dismissed this as one of the local vehicle recovery lorries, bumping over the speed humps, as they do. But the second band was much, much louder.
“You could feel it through the floor of the house. We decided to investigate so we went outside and saw huge plumes of black smoke, and the undeniable smell of burning rubber.
“We walked down to see what was going on. The emergency services were on site within minutes and we continued to watch the fire service attach to the hydrant and start soaking the flames and the police cordoned off the immediate area.
“The garage forecourt has been destroyed by the heat and most of the roof structure buckled.”
The first reports of the blaze were received at at 9.31am on Monday.
West Sussex Fire and Rescue Service received multiple calls to say a campervan was on fire on the forecourt of the Shell garage in Fontwell.
At about 10.30am a spokesman said: “We are currently in attendance at a fire at a petrol station in Fontwell off the A27.
“Police also at the scene. Please avoid the area.”
“Three pumps were mobilised along with a water carrier. Six breathing apparatus, two jets and one foam jet were used to extinguish the fire.
A police cordon was set up and a number of nearby businesses and properties were temporarily evacuated as a precaution.
“The incident was handed over to police and we left the scene at around 2pm.”
