I didn't think so, but in fact it does - then it wiggles down Lambeth Road to St George's Circus, and heads up Blackfrairs from there. Cycle route in joining-up shocker.
I'm pretty chuffed about that - my family are all up norf, so KGX is the station I use to go home. Now I can go from my place in Balham to KGX on superhighways all the way.
I can see how it would be good if you were going up St. George's (oo-er). Does the N-S highway to King's Cross go up there or is it the other turning?
