During my UK swing my first day in London I was told to go check out this new cycle track recently installed on College Street. It's wonderful. It reminds me of the Tactial Urbanism style of Mike Lydon or Jason Roberts. Very exciting, the street has a protected bike lane on one side and on the other a contra-flow, parking protected bike lane going the other way on a 20mph street. The coolest part though are the very lovely planters and armadillos bolted into the pavement to keep drivers from driving or parking in them.
And it has a fun cycle counter to boot!
