It sounds like how Railton used to be pre-LTN. Sorry I don’t know much about the local road layout but here, Dulwich road takes the traffic, could Acre/Bedford do the same if ferndale was blocked off?It’s still congested at times, new rush hours at various times including for Ubers at the weekends. Noise and arguments still happening - the increased traffic on Ferndale Road West as the only entry/exit is not nice for peoples mental health.
