The A4 Hogarth Lane is currently closed in both directions after an HGV collided with the central reservation overnight, resulting a large diesel spillage damaging the road surfacing on both carriageways. All six running lanes need to be resurfaced over a 30 metre long stretch of road between Junction 3 of the M4 and the A4 Hogarth Roundabout.

Garrett Emmerson, TfL’s Chief Operating Officer for Surface Transport, said: “Following a lorry collision a large amount of diesel was split, damaging all six lanes of the A4. I would like to apologise to motorists for the disruption and reassure them that we are working hard to reopen the road as quickly as possible. The carriageway needs to be completely resurfaced over a 30 metre length which we expect to be completed by mid-afternoon.”
