I have never seen a TFL map available online showing the various cycle superhighways; however, someone did put one together recently and the pattern of the routes is striking, see link below. Hint: it's not what is there, but what isn't there.

Here is the Google map.

Yes, we have a quietway close by, but a quietway is defined as routes to "overcome barriers to cycling, targeting cyclists who want to use quieter, low-traffic routes, providing an environment for those cyclists who want to travel at a more gentle pace" (source). This does not support people who are commuting into London.

I was not living in SE London when the cycle superhighways were first introduced, but I do wonder whether the response from our local government at that time was apathetic, or just pathetic.

There is seemingly no will to invest/improve the road network passing through Forest Hill as noted by Chrisse, the only hope for improved rail links will be when London Bridge re-opens, there is scope for improved bus links (why is it so hard to get to Clapham, for example -- there isn't even a bus route following the south circular), and there is scope to improve the cycle routes into Central London.
