M4 Closure Westbound, Greater London. Monday 23 May 2016
The M4 in Greater London had 3 lanes (of 4) closed between J4 – J4B on the morning of Monday 23rd May due to a heavy goods vehicle (HGV) overturning and spilling diesel on the carriageway.
At approx. 07:17hrs the Metropolitan Police notified our East Regional Control Centre that they were getting reports of a serious collision on the M4 Westbound between J4 (the exit for Heathrow Airport) and J4B (the exit for the M25).
A 7.5 tonne lorry had turned over and spilled a significant amount of diesel across the carriageway. An ambulance attended promptly (at scene by 07:27hrs) and thankfully only a slight injury was reported. The M4 westbound was initially blocked and London Fire Service were asked to attend, with a view to preventing further diesel being spilled onto the road surface.
Our Traffic Officers were also in attendance and helped to re-open lane 4 (of 4 lanes) past the scene of this incident, at approximately 07:41hrs.
It was quickly established that nearly 100 litres of diesel had been spilled onto the road surface. Our Managing Agent Contractors arrived at scene within 1 hour of this incident occurring.
At 09:51hrs, the recovery team at the scene of this incident established that the HGV was too heavy to lift. It took approximately 30 minutes to ‘decant’ the contents of this lorry to a safe area. The HGV’s load was food based, including drums of oil and frozen meat.
The carriageway was assessed to see if resurfacing was required and at 11:21hrs, the outside 2 lanes (lane 3 and 4) had re-opened.
Our contractors advised us at 13:19 that it would not be necessary to resurface the carriageway and at 13:28 all lanes were fully re-opened
There were severe delays throughout the incident which were particularly high (above 70 minutes) from 08:50 to approx 11am, unfortunately affecting traffic near Heathrow. Upon re-opening of the carriageway the delays had all but cleared and traffic was flowing well.
