A transformer the size of a house is set to complete its 10-hour journey through Kent tonight.

The supersized load, which weighs in at 318 tonnes, is due to leave Port of Dover at 9pm tonight on a specialist vehicle, which measures in at 87 metres long and 5.8 metres wide.

It follows two false starts, when the scheduled journey was cancelled twice this week.

The large load will be joined by Kent Police and it's so big that it needs two trucks, one at the back and one at the front, to propel it.

The transformer will be travelling at a top speed of 12mph.

It is scheduled to travel along the A20 to the Alkham Valley Road junction (A260 – Canterbury Road), onto the A259 to get onto the M20 at junction 13.

The transformer will leave the M20 at junction nine and re-join it to travel back to junction 10. It has to go back on itself because of weight restrictions at the junction.

It will then leave the M20 at junction 10, travelling along the A20 and Church Lane before reaching the Sellindge electricity converter station.

The transformer is expected to arrive at around 7am tomorrow.

National Grid's project engineer James Sheridan earlier said: "If people could please avoid parking on the route - particularly on narrow areas - it will ensure we get the transformer from the Port of Dover to Sellindge converter station as quickly and efficiently as possible."
