It's good to have that blocked off, but it precludes making a good protected cycle crossing of Norwood Road. Anyone coming from the nice protected LTN has to either brave the gyratory and south circular, or battle through traffic on Norwood Road before turning off. There's road space for something like:

Which, in combination with a safe crossing of the S.circ at Elmcourt -> Lovelace Road, would provide a safe route all the way up to the protected route on Rosendale Road (soon to be extended all the way to the crossroads at The Rosendale pub)
