ONE of the largest loads to ever be moved through Wiltshire is expected to cause congestion at the weekend.
A giant transformer will be ferried from Avonmouth Docks to a substation in Melksham on Sunday morning.
The specialised transporter and its load will measure 5.10m wide, just shy of 65m long and weigh 254 tonnes.
It will leave Avonmouth at around 6:45am and travelling at a maximum of 12mph, it is expected to take five hours to reach Leigh Delamere services on the M4.
From there it will leave the M4 at junction 17 heading south on the A350 towards Chippenham and then onto the A4 towards Corsham. This section is expected to take around three hours to complete.
The final two hours will see the transporter turning onto the B3109 and then the A365 towards Melksham.
Because of the size and slow speed of the transporter Wiltshire Police are advising people to ensure they allow plenty of time to complete any planned journeys.
