Like the idea of the town square around the station, as the station is very much the reason why Forest Hill actually exists at all: it was the railway that came first, then the houses.
What's really wanted in FH is a by-pass road, to get rid of the through traffic.
Just try crossing the road by the launderette to get to the station and stand back when those massive artics manage to just make the turn: watch your feet!
The S. Circular Road has very few dual carriageway sections; it is just a collection of local roads with difficult junctions like FH and Catford. The big trucks have to use it because of weight restrictions, but it brings noise, dirt and danger to many communities in S. London.
In the 1960's the GLC (Greater London Council) had plans for the "London Ringways", and the S. Circular should have been upgraded to to Ringway 2, but public opposition (and the proposed demolition of so many properties) meant that the plans were dropped.
And there was also that idea about the road tunnel under Horniman's ....also long forgotten.
