Traffic delays Sunday 30 July as giant transformer on the move

On Sunday 30 July National Grid will be transporting a very large piece of new equipment to Iron Acton substation. The lorry carrying it will be 57 metres long by 5 metres wide and weigh 231 tonnes. Due to the size and weight, the lorry will travel between 10 and 15 miles per hour.

The vehicle will start from Avonmouth Port in Bristol on 30 July at 9.00, arriving at Iron Acton substation in the late afternoon. It needs to avoid hazards such as weak bridges and narrow turning points, so the route is quite indirect:

Avonmouth docks - M49 - M4 - M5 northbound to Junction 13, then returning southbound to Junction 14, where it will exit onto the B4509.

Then Cromhall, Bagstone and Rangeworthy, and then following the B4059 until it reaches Latteridge village, close to its final destination.

If anyone has questions or concerns, they can contact National Grid's Community Relations team on 0800 073 1047. They are available seven days a week 7.00 – 19.00.
