National Grid will be transporting new transformers to the Iron Acton sub-station on Sunday, July 30, to replace old equipment at the site.

A heavy haulage lorry will carry the transformers, which are needed to change the voltage of electricity before it is transmitted through the power network.

The vehicle is due to set off from Avonmouth at 9am but due to the indirect route it will follow, won’t get to Iron Acton until between 3pm and 3.30pm.

Measuring 187ft (57 metres) in length, the lorry will weigh in at 231 tonnes and due to its size and weight will only be able to travel at between ten and 15mph.

National Grid said a police escort and haulage team would accompany the lorry to ensure the safety of the public and its team.

The police will also manage traffic and stop vehicles for a short time at certain places, such as when the lorry needs to straddle two road lanes, turn or travel along narrow roads.

 The route chosen avoids weak bridges, narrow turning points and other hazards and after leaving Avonmouth on the M49, will go east along the M4 before joining the northbound M5.

It will then continue to junction 13 at Stroudwater before returning on the southbound carriageway to junction 14 at Falfield, where it will join the B4059 and head up Tortworth Hill.

 The route then goes through Cromhall, Bagstone and Rangeworthy to Latteridge and its final destination. 

Paul Taunton, project engineer at National Grid, said the route had been planned with Allelys Heavy Haulage to keep disruption to a minimum.

However, he said: “There are likely to be some delays on the Sunday morning on the motorway and on smaller, narrow roads close to the sub-station. 

“Our last delivery to the sub-station was successful with little disruption to roads in the area and we expect the same this time.”
