LISTEN: Jeanette Unsworth from the National Grid gives details of a giant transformer passing through Kent - 17/08/18

A giant transformer will be travelling over the Dartford Crossing this evening - potentially causing delays for drivers.

The 143-tonne structure is set to make its way over the QE2 bridge at 10, which will be closed for about 20 minutes while it makes the crossing into Kent.

A 68 metre long transporter will carry it at 12 miles per hour from Essex to a substation in Weybridge.

Jeanette Unsworth is from the National Grid.
