Also at Limehouse Basin is a swing bridge. If you're unlucky, it's swung when you arrive, and you have to wait a couple of minutes while river traffic shuttles between basin and Thames. 
No. The actual barrier across the CS3 is further on, here in East India Dock. If you can find it after the blue paint mysteriously runs out for a few hundred yards. 
Dr Bike sessions are pretty regular things round London: council-subsidised roadside stalls where you can stop off on your morning or evening commute. 
We were at last Thursday's very well-attended Oval one (above and right), and it's the best site we've seen for a Dr Bike: right on a major commuting route, and prominently visible to cyclists stopped at the lights just beforehand, giving them plenty of time to see the stall and decide to stop.
These are popular. The wait for a free mechanic can be half an hour in peak time. While waiting, you can stroll across to Oval station and pick up your free Evening Standard to read cover to cover. Still leaves another twenty-seven minutes to fill, though.
Still, they're there for a good purpose. We need the signs to give us directions and information. 
Just west from here is the start of the new CS3, from Barking to Tower Bridge. Obviously, being a Cycle Superhighway, the cycle track is different from the sort of nonsense you see here. 
The Cycle Superhighways were officially launched this morning in a marquee on Clapham Common.
Funny, though: the water bottles were superbly branded with 'Cycle Superhighways' on the outside, but when I examined the contents, there was nothing but hot air.
But in the Speeches, David Brown of TfL made a valiant effort to justify the multi-million pound expenditure on the cobalt-coloured calamities. 
Still, after a reassuringly dull speech from a Barclays rep - reassuring because I don't want a comedian looking after my mortgage, thank you, I want a reliable plodder – you could sense the relief when Boris stepped up to the plate. 
Yes, he'd cycled here, at "the pace of an elderly French onion seller", obeying all the traffic signals and "stopping like a pillar of salt at the lights". Yet it had taken him just 35 minutes from Islington, during which time he had overtaken a boy-racer several times in an open top sports car. 
The Cycle Superhighways launch tomorrow, and the last-minute preparations were being done on CS7 yesterday when we cycled along it from Tooting to Southwark Bridge.
There's even a 'north' pointer set in the pavement at the bottom, so you can reorient yourself after a bus knocks you off your bike.
The chaps installing the info post joked that the pink logo of the bike rider is based on Boris Johnson. As the rider appears to have no grip on any steering mechanism, perhaps that's appropriate.
We think this is a splendid idea, as it adds yet another useful piece of route labelling. You need this a lot on CS7, where the blue stripe disappears constantly under parked cars, and the blue squares in the middle of the road are submerged by buses.
While this - which reminds me of those student graduation projects for a 'radical new design of bike' - adorns the entrance gate to Regents Canal towpath on Lisson Grove in Islington, just down from the Beatles' Abbey Road crossing.
And this is the Bicycle Magic shop in Greatorex St, near Brick Lane, in east London. We like this.
This stretch of the Safe, Direct and Continuous new magic carpet for cyclists is on Southwark Bridge Road.
As the mayor Boris Johnson said when the Superficial Cycleways were first announced, "these are routes where the bicycle will dominate"!
Most of them are covered in black plastic bin liners for now, which is possibly a comment on the standard of the facilities they advertise. 
A sign on the top of the stem reminds you not to go up the inside of lorries. We hope there's a complementary sign inside that HGV cab from Lithuania that scythed horribly across me at the Elephant the other day. 
And, like me, you're probably not claiming enough road space. For instance, when waiting at a junction with oncoming traffic to turn right, you're waiting too far over to the right, then getting squeezed between the oncoming traffic, and traffic going straight on that you've therefore allowed past. 
Women are much more likely to take cycle training than men. The blokes, apparently, think it's a bit juvenile, and smacks too much of boyhood and Cycling Proficiency adverts with Keith Chegwin (right and below right). 
After all, it's the same trick TfL have pulled with the 'conversion' of existing cycle routes to 'Cycle Superhighways'.
Take this example. You're heading north-east up Kennington Park Road, just past the Oval cricket ground (top three, and bottom two, pics). 
It seems that the engineers, acknowledging that there is no safe way, in the present road layout, for cyclists to make the straight-ahead movement, have decided not to commit themselves by recommending a way. 
The CSs are not even 'just a blue stripe'. In many places - such as Narrow St (right) on Superficial Cycleway 3, Barking Mad to the Bloody Tower Gateway - they're a disjointed series of hopscotch squares. 
They add no new safety features. (Some bits of the existing bike routes, such as Cable St and the Elephant and Castle by-pass, have been smoothed, resurfaced, and slightly widened in very short stretches. And that's good, thanks - but that's all stuff that should have been done anyway.)
They're not continuous. (They stop wherever there's a bus stop or a parking space - that parked car is there quite legitimately.)
However, someone ought to have a word with them about their bike. It appears to lack independent front brakes, thus contravening the Pedal Cycles (Construction and Use) Regulations 1983 (Statutory Instrument 1983 No. 1176). 
Nevertheless, watch and learn. Such tumbling and manoeuvring skills will be very useful for negotiating the dog-legs, hairpins and discontinuities of the Cycle Superhighways opening later this month.
Further along the CS7 route, on Southwark Bridge Road, is this van. The blue stripe for the Superficial Cycleway 7 will go here, right along this stretch of double-yellow-line no-parking mandatory-cycle-lane. Let's hope the van isn't still parked in it when they bring the tin of paint round, or it won't be a white van much longer.
So, overnight, like a silent fall of cobalt snow, Kennington Park Road now has its own stretch of Superficial Cycleway, out of a tin. Like spray-on blue tan, it's that easy!
