They've just slapped down some nice new blue-paint squares on Cycle Superhighway 3 (Barking to Tower Gateway) here on Narrow St, just south of Limehouse Basin, a couple of miles east of Tower Bridge.
The squares aren't joined up, like most of London's cycling policy, but we assume that in due course, blue strips will extend continuously along both sides of the road. Um, won't they?
(Just west of here, bound up to the Superficial Cycleways route by some arcane 4D Riemann transformation comprehensible only to topographical maths genius Grigory Perelman, is the bizarre Horseferry Road contraflow, which I blogged about in February.)
Now, I'm no expert on etymology, but I suspect it's possible that Narrow Street's name may be related to its restricted width. And at the moment, as the picture (right) shows, it's clearly too narrow to have two Superficial Cycleway lanes, two lines of traffic, and parking spaces.
So what's going to happen to the parking spaces along this road? Will they be removed, and the blue squares joined up, to make CS3 'safe, direct and continuous'?
There may be a satisfactory transformation that doesn't involve losing all that valuable onstreet parking, but you'd need Mr Perelman to work it out. And another couple of dimensions.
