Some delays are expected on the M6 this weekend when a ‘supergrid transformer’ is escorted along the motorway.

National Highways say the abnormal load transport will take place on Sunday (January 18), but no time has been provided at this stage.

The massive transformer will be loaded onto the transporter at Heysham Port and leave for the motorway at around 8am.

It will join the M6 at junction 34 (Halton Interchange) at Lancaster and slowly make its way north for 70 miles to Carlisle.

It'll arrive at National Grid's Harker substation in the afternoon, subject to traffic and weather conditions.

The journey is expected to take between three and four hours, with an average speed of around 20mph.

It will be joined by an escort to help manage traffic. The agency is advising motorists to allow extra time for their journeys.
