The Sheppey Crossing was closed twice today after two vehicles broke down in thick fog.

Kent Highways urged motorists to take extra care as a blanket covered the county - and the Met Office issued a weather warning, saying visibility was reduced to 100 metres or less in places.

Police were first called to the Sheppey Crossing at 5.10am when a BMW came to a halt just off the Sittingbourne-bound carriageway.

Due to poor visibility, officers closed the road until the vehicle could be escorted to safety.

It was reopened just before 6am and no one was reported injured.

But the crossing was then closed in the other direction at about 9am because of a stranded minibus.

A police 4x4 was sent to the scene to clear it, while traffic was diverted via the Kingsferry Bridge. It was fully reopened by 10.30am.

The Sheppey Crossing was the scene of a 150-vehicle crash in thick fog in September last year - one of Britain's worst-ever - in which 40 people were taken to hospital.

A mother and her eight-year-old son also died following a crash on top of the bridge on July 1.

Earlier, a Met Office spokesman said: "The public should be aware that this will lead to difficult traveling conditions during this morning's busy period."

Kent Highways said on Twitter: "Areas of low mist and fog across the county this morning. Please drive to the conditions of the road ahead."

The fog was expected to gradually lift and disperse by about 9.30am.
