A short section from Well Hall Road to Eltham Road had been completed by 1930, aside from a bridge underneath the Hither Green – Dartford railway, and the road had been built as far west as Burnt Ash Hill by the middle of the decade. Sir Charles Bressey's "Highway Development Survey" (also known as the Bressey Report), published in 1937, showed a -long South Circular that would have a new-build section near Wandsworth Bridge (then being rebuilt) but otherwise be a series of online improvements to existing roads.
