Illegal path diversion? (Sustead FP 10)

Between the grid references TG 1967 3653 and TG 1971 3627 the path (as depicted on the Norfolk County Council map at http://maps.norfolk.gov.uk/ highways ), both in terms of what is apparent on the ground and what has been signposted by the Norfolk County Council (as a "Norfolk Trail"), has effectively been diverted onto a completely different line running to the east.

The mapped (correct) path line is substantially obstructed.

The signposted diversion is itself subject to a stile in a poor state of repair (no limitations are recorded on the definitive line) and overhanging vegetation. The photographs all show the signposted diversion.

Message to Norfolk County Council: How has it come about that you, as the highway authority, have signposted the wrong path line? Why have you failed to signpost, and assert and protect, the correct line? What are you going to do to put things right here, and when?
