There were severe delays this morning after a circus lorry caught fire in a car park.
The blaze happened at Zippos Circus in Brent Cross and 21 firefighters and four fire engines rushed to the scene.
The exit slip road on the A406 northbound near the Holiday Inn is still shut.
Meanwhile, the trailer is still alight and firefighters are trying to cool a number of propane cylinders.
They fear they could explode when exposed to heat.
