Yes, it was to have continued as far as Balham, from where spurs would

In which case it really WOULD have become the 'Gateway to the South'

LOL! Although I think Balham's grand vista of ever-changing lights (red,
red and amber, green, amber and then red again) might have been a bit
sub-optimal for a motorway.

(According to the WIKI entry on Balham, "Gateway to the South" was an
actual advertising slogan used by the Southern Railway in 1926 when the
Northern Line tube station opened adjacent to their own station - but I
find it hard to believe!).
