Town planning and cycling a.k.a bad junctions

If they'd been kept to a single lane all the way over the bridge I am convinced that traffic would have kept flowing, with fewer risks for everyone.

I'll agree, the first couple of weeks will be neck-to-neck congestion before people adapted and either take other transport or direction.

I think Ken Livingstone created further congestion back when he was a mayor which encourage people to take different mode of transport instead.
