All the updates as M4 fully reopens 12 hours after lorry carrying steam roller smashes through central barrier

There were severe delays on the M4 near Bristol and into Wales after a lorry struck the central reservation barrier and shed its load on the motorway. The accident affected the motorway between the M5 junction at the Almondsbury Interchange and the M48 until around 3.45pm when all lanes reopened after emergency repairs to the barrier. The main carriageways were closed after the lorry hit the central barrier shortly before 4am and spilled its load, which included a steam roller, on to the opposite side.

Traffic was using the hard shoulder in both directions before lanes gradually reopened during the day.

The crash scene this morning

By 9.30am, delays were more than an hour and 40 minutes after both carriageways reopened with a lane closure in both directions. By 1.30pm, only one lane was closed eastbound after the vehicles had been removed. There were long delays of up to 16 miles back into Wales with the eastbound M48 being closed to reduce traffic heading towards the aftermath of the incident.

Motorists felt delays to their journeys of up to one hour and 40 minutes. The M5 was also affected. Highways England had warned normal traffic conditions weren’t expected until around 7pm, but repairs were completed and all lanes reopened before the evening rush-hour.
