Back between the wars a new arterial road was planned running from Chessington to Sutton. It was never built but the route was still being safeguarded when I joined RBK in 1974. We had a map of it in the RBK planning office. While I was working there (c.1976?) the safeguarding was lifted but legacies of this plan remain.
The road (see the Sabre roads website Lost Arterial A24 for more detail) entered New Malden just south of the A3 then would have run along what are now Sheephouse Way and the end of South Lane – now you know why they have such generous grass verges. It would then have run across Malden Park and the railway. The line on the map above (from freemap.org) gives a rough idea of the intended route.
Look at the map and you’ll see a green swathe between Pembury Avenue and Risborough Drive. This was left undeveloped in the when Wates developed this area as the Worcester Park Station Estate in the 1930s and is now called Risborough Green. Rumour has it that its elevated ground level is down to the site being used as a dump for WW2 bomb site rubble.
The site between 133 Pembury Avenue and 200 Kingshill Avenue was also set aside for the new road – it’s now been infilled with a block of flats, Primrose Court. The houses on the other side of the road are much newer too.
Hopefully someone reading this knows a lot more about this road than I do. If so, please add a comment.
