not only do I believe you, Stowie, I've cycled past the signs saying 'no cycling'. And I was, by a stretch, the fastest thing on the road - despite my advanced years.Not only would it be deeply unpleasant to cycle on the A12 link road (never tried, but I can use my imagination), it is actually illegal. Check out street view at the Green Man junction Leytonstone if you don't believe me. Or the Leyton junction next to the Olympics.
The A11 isn't too bad until before Bow flyover, and then it becomes diabolical (in my humble opinion). And it is much worse at the moment since the bus lane into Stratford is closed for road-works so one has the task of either fighting through traffic in the busy times or trying to prevent close passes by maintaining as primary position as one dares when the traffic is light. And, call me cynical, but the reason the CSH will stop at Bow is that the bow flyover is a problem that will require significant cash and / or reduction in road capacity for cars if anything is going to help cyclists on this stretch. Still, there is a consultation for extension, which sounds promising that TfL at are least looking at it.
And, yes, we agree entirely about Stratford. The CSH's (sorry) funk some big choices which is why we await the west London CSH's with some uncertainty. I don't personally think that capacity is the problem at the roundabout, because it's the northbound on-ramp that causes the problems. I'd have thought a first step would be consideration of the kind of junction we have under the A20 at Kidbrooke, or the A406 at Ilford (but upside down, if you see what I mean)
Wood Street is a mess (I've not been down it for a long time) but it's not an arterial road. It's one of those roads which is just the wrong width. Ken wanted to simply cut out parking on streets like Wood Street, but Johnson is of the opposite persuasion. Either way the design of the parking scheme is pretty silly, but I'm not sure that you can lay it at the door of TfL. It's a B-road. Is it on the TfL Road Network?
