The irony is that while the traffic in Sydenham around the roadworks is slow, it still moves faster than the traffic on Dartmouth Road when it bunches, especially mid-afternoon between 3pm and 5pm. Recently, and more than once, it has taken me 20 minutes to get from the library to FH station at that time of day. Quicker to head to Cobbs Corner in Sydenham and wait for the temporary lights to change or head up the hill to the Horniman and back around via the South Circ where traffic flows well.
