Motorists in Gloucestershire and Wiltshire are being warned that an abnormal load will be travelling through the counties tomorrow morning.
A Boeing 737 fuselage will be transported from RAF Kemble to Hereford starting at 7.15am, and escorted by police.
From Kemble the convoy will travel along the A429 towards Cirencester. It will then travel south on the A419, before joining the M4 westbound at junction 15.
Due to the size of the transporter it will be slow moving and will have the potential to cause congestion. While travelling on the A419 it will take up both southbound carriageways.
Police advise motorists to allow extra time for their journey if travelling around this time.
