An abnormal load, weighing the same as 14.5 double decker buses, will be escorted from Ipswich to Cambridge this weekend at a top speed of 20mph.
The load, a National Grid electrical transformer weighing 184 tonnes, is being moved from Cliff Quay in Ipswich to a substation in Burwell, Cambridge, on Sunday, June 6.
It measures 6.67m long, 5.35m wide, 4.67m tall and the total length of the transport vehicle will measure 60m.
While driving through built-up areas, the vehicle will travel at walking speed, then should be able to get up to 20mph on main A roads — over the Orwell Bridge it will move between 10-15mph.
Specialist trailers will need to be used to support the weight of the transformer and alleviate pressure on the roads.
Suffolk Highways has been working with Highways England, Suffolk and Norfolk police, Allely, and Cambridgeshire County Council to prepare for the next abnormal load.
Suffolk Highways has already carried out some preparatory road sign removal works on Landseer Road and Nacton Road in Ipswich, as well as the A142 Fordham Road, Newmarket.

The road signs will be reinstated the following day at 7pm each evening, with temporary traffic signals in place for approximately three hours while the work is carried out.
Lanes on the A14 at Newmarket will briefly close to let the load cross over the westbound to eastbound carriageway for the A142 slip road.
To get around permanent street furniture, the load will be on the opposite side of the carriageway at times. Police will enforce rolling road blocks at crucial points, such as crossing the Orwell Bridge, where both carriageways will be closed.
There will be stop off points where traffic will be released to mitigate congestion.
