Sussex police have warned of temporary disruption on roads between Patcham and Lewes on September 27 as three large loads will be moved to a wind farm.
The loads will be moved from docks at Purfleet in Essex into Sussex down the M23, then on to the A27 at Patcham, turning left along the A27.
They will then continue through Cuilfail tunnel on the A26 at Lewes, before heading up the B2192 towards Ringmer and then turning right into New Road.
Motorists on these roads are advised to take extra care while driving on Tuesday afternoon when the loads, believed to carry the base, pillar and turbine elements of one wind tower, will be transported.
A Sussex Police spokesman said: "The loads should be travelling at up to 40mph so we hope that the whole exercise will be completed before the afternoon rush hour starts.
"However there may be some delays as the first of the three loads manoeuvres onto the A27 at Patcham, and again as it goes through the Cuilfail tunnel, which will have to be briefly closed to other traffic."
