An ambulance transporting a patient caught on fire at the Interstate 66 and Route 28 interchange in Centreville, Virginia, Tuesday evening.
The privately-operated ambulance burst into flames on a new, elevated ramp that sends eastbound drivers on I-66 northbound onto Route 28. Flames were seen ripping through the hood and roof of the vehicle.
The patient was safely evacuated from the burning ambulance and later transported to the hospital in another ambulance, according to a Fairfax County Fire and Rescue spokesman.
The fire was extinguished shortly after 6:30 p.m. The ambulance crew was not injured.
The cause of the fire is unknown.
An inspection of the flyover ramp is expected to take place on Wednesday.
