The B359 is a short road in Hampton Wick, on the edge of Bushy Park, whose existence is disputed.
It starts on the A308 Hampton Court Road, to the west of Kingston Bridge. It heads north along Church Grove for under a quarter of a mile before ending on the B358 Park Road.
According to OS mapping, and the single sign showing the junction, the southern end of the B358 has now moved and taken over the entire route of the B359, making that road number redundant. However, A-Z mapping still shows the road as live, and Richmond-upon-Thames council's own road list agrees with them. While the council - responsible both for its own list, and for the signage - cannot make up its mind, the question of the number of Church Grove is unlikely to be resolved any time soon.
