Motorists in Suffolk are being warned to watch out for traffic delays as three abnormal loads slowly make their way along the county’s roads over the next two weeks.

The massive cargo, weighing around 140 tonnes, includes two electrical transformers and two electrical reactors, all destined for the Galloper Wind Farm at Sizewell.

The first transport, carrying electrical transformers, will hit the road today, Wednesday October 26, as part of its 170 mile journey from the Immingham Terminal in Lincolnshire, travelling at no more than 20 mph all the way.

The next two transports, both carrying electrical shunt reactors, will hit the road on Monday, October 31 and Thursday, November 3.

The slow-moving vehicles will be 38 metres long and three metres wide - the length of two HGV’s end to end - and will hit the road between 12pm and 4.30pm.

The planned routes will see the huge transports travel through the county along the A14 eastbound before taking the slip road at the Seven Hills roundabout onto the A12.

They will then make their way along the A12 past Martlesham, Woodbridge, Wickham Market and Saxmundham before turning onto Middleton Road (B1122) to the Sizewell Gap.

Toby Edmonds, Galloper Wind Farm project director, said: “We are genuinely sorry for any delays or disruption the deliveries might cause but it is essential that the journeys are trouble free. “These components will be vital to enable electricity generated by Galloper Offshore Wind Farm to reach homes and business. “Once operational in 2018, the wind farm will be capable of generating enough energy for over 300,000 homes.”

The abnormal loads will be escorted by heavy-load specialists Collet and Sons Ltd, who transported a 170-tonne National Grid transformer to the Sizewell onshore site on October 1.
