Trilby Rd, Cibber Rd, Vestris Rd, Farren Rd, and Shipman Rd form a strange warren of roads that are possibly harder to police - plus the lack of road access to Sunderland Rd does not help.

It is very odd how this should come about - does anyone know?
Even the old map of 1799 shows a prototype Vancouver Rd cutting through the stansted Rd/Perry Vale/Catford Hill triangle in an orderly way, seemingly headed to directly link up with London Rd on the other side, only to be brought to a sudden dead end just about where this knot of roads is today.
Curious.
