A major motorway has been shut following an oil spill causing massive delays for motorists.
Drivers on the M4 are experiencing lengthy queues between junction 12 for Theale, Berkshire, and junction 11 – the A33 connection at Reading south, which remains closed this morning.
A diversion route is taking traffic through Reading itself, which has now become heavily congested. An overnight collision led to oil being spilt across the carriageway, with emergency teams still working to clear the mess.
National Highways states: “A full closure has been implemented to allow service providers to work on scene to resurface the road.”
National Highways has provided the following diversion route:
- Exit the M4 at J12 Theale Interchange and at the roundabout take the first exit on to the A4 Bath Road towards Reading.
- Continue on the A4 towards Reading and at the traffic light controlled junction with the A4155 near Southcote turn right to remain on the A4 (Berkeley Avenue).
- At the traffic light controlled junction with Rose Kiln Lane turn right.
- Follow the Rose Kiln Lane to the traffic light controlled junction with the A33 Basingstoke Road and turn right.
- Follow the A33 Basingstoke Road southbound to the M4 J11 Three Mile Cross Interchange.
- At the Interchange roundabout take the second exit to re-join the M4 eastbound.
