Due to ongoing coastal erosion in this area, this bit is no longer considered safe to drive on and on the inner corner a triangular area has been surfaced to create a diagonal connection between the Beach Road and the car park. It's clear this is no longer considered a t-intersection as is drawn on the map, but this is the main course of the road now. Until the Sea takes more I guess. Also, if the line with the triangles is supposed to indicate the edge of usable land, it needs updating since the erosion has already reached the Blake Cottage fence and the corner of the eastern car park.
