A huge 87 metre long transformer struck a motorway bridge as it made its way through Kent at just 12mph.

The load, which is an electricity transformer, left the Port of Dover at 11pm last night, on its way to a substation in Sellindge.

It was said to be the size of a one-bedroomed house and nearly six metres wide.

Witnesses reported seeing it hit a bridge.

All lanes of the M20 have now reopened after the accident on the London-bound stretch of the motorway between J11A (Channel Tunnel) and J11 (Hythe/Westenhanger).

A police spokesman said the accident happened at 2.30am today, but the transformer is said to have just "brushed under" the bridge.

There are no reports of structural damage.

Two lanes were closed while the accident was dealt with.
