I have finished laying down the course of the routes that make up a revitalised London Cycling Network. As always, these maps are best viewed with the terrain box ticked.
Navy Routes
Side-to-side routes 205.8 mi
Additional routes 45.1 mi
Total 250.9 mi
Red Routes
Side-to-side routes 221.4 mi
Additional routes 54.7 mi
Total 276.1 mi
Green Routes
Side-to-side routes 236.4 mi
Additional routes 35.3 mi
Total 271.7 mi
Cyan Routes
Side-to-side routes 255.2 mi
Additional routes 45.3 mi
Total 300.5 mi
Orange Routes
Side-to-side routes 213.2 mi
Additional routes 66.5 mi
Total 279.7 mi
Circular Routes
Total 11 mi
Grand total: 1389.9 mi
Average (not including Circular Routes) 275.8 mi
North-south ('cold' colours) 551.4 mi
East-west ('warm' colours) 555.8 mi
Certain sections of these routes are coded with more than one colour (bridges, for example), so the actual network distance is going to be somewhat less than the stated total. Something a little over 2200km would be my guess. But the LCN was 3000km, the LCN+ was 900km, and the Cycle Superhighways are whatever they are, and when you consider that pretty much all three networks are incorporated into this new design, you'd have to say that 2200km of network is not excessive, not by any stretch of the imagination.
Granted, the network as shown does not cover all of the Greater London area, and working out which routes should make up the rest of the network, and how they should be coded - which I have looked at, but not for a while - is something that will need to be addressed.
