Road users in the Westbury, Trowbridge, Melksham and Chippenham areas of Wiltshire may experience delays on Monday 15 April.
An abnormal load is to leave Brook Lane, Westbury at 11 am and travel along the B3097 to Trowbridge, where it will join the A350 before travelling onwards through both Melksham and Chippenham to the M4 at Junction 17.
The packet will consist of the prime mover plus both private and police escort vehicles, with the load itself being a steel fabricated structure, 4.6m in width.
Due to its size, the load will be both slow moving and have the potential to cause congestion in places where oncoming traffic will be required to pull in and wait for the packet to pass. Traffic travelling behind will not be able to overtake.
Wherever possible, disruption will be kept to a minimum although both hauliers and motorists are asked to please be patient should they come across this load. Anyone travelling over this period on time critical matters should allow sufficient additional time for their journey.
Police escorting resources are being provided by officers, paid for by the haulier at no cost to the public.
