Thirty firefighters are still putting out flames after a huge fire closed part of the M1 and a busy stretch of the North Circular over the weekend.
More than 100 firefighters tackled the blaze, which started in a woodyard in Staples Corner, north London, on Saturday afternoon.
Smoke is still blowing across the road on the A406 Westbound.
Traffic is also moving slowly on road because of the closure of a slip road as a result of the fire.
An investigation into the fire is under way.
