Police are warning motorists to expect traffic delays on Sunday as a large boat will be moving across Norfolk and Suffolk under police escort.
The boat, which is more than six metres wide, will leave the village of Ashmanhaugh at 7.30am and travel along the A1151, A149, B1152 and A1064 until it meets the A47 at Acle.
It will then travel west to the A11 and south into Suffolk.
The police escort will continue until it reaches the M11.
Traffic will be stopped in various places whilst the boat passes.
