A21 southbound and northbound slip roads at North Farm interchange

Incorrect and unnecessary elements on the roundabout map signs on both slip roads at this interchange make the signs confusing and load unnecessary information on drivers. The roundabout signs on the slip roads do not need the A21 panel as drivers have just left the carriageway, and the roundabout cut out and width of the vertical arms are incorrect. Something similar to a redesign I did a while ago (pictured for the southbound slip road) would be better (note: my design includes an additional tourist and lorry destination sign that would be placed a distance after the roundabout sign)
