This video footage shows the extent of the huge out of control bonfire - and the impact it had on traffic.
The Transport for London (TfL) traffic cam footage shows traffic building up near the A40 Western Avenue after the fire resulted in the closure of two lanes near the Polish War Memorial.
It is thought the fire started shortly after 5pm on Tuesday (October 31), with TfL not announcing the reopening of all lanes until close to midnight.
The footage shows large plumes of smoke drifting off into the sky at Ruislip , while the flashing lights of emergency services can also be seen.
A second video shows the impact it had on roads, with a long stretch of traffic seen backing up along the A40 Western Avenue and into the distance.
London Fire Brigade said 30 tonnes of waste caught fire in open land close to Western Avenue between the RAF Northolt and the Polish War Memorial.
Six pumps were sent from Northolt, Southall, Ruislip and Hillingdon to tackle the blaze.
With visibility affected, congestion stretched back all the way from Westway to White City on the A40.
