Believe it or not, our Good Facility this week is in the London borough of Westminster - not exactly well-known for doing things well.
The northern end of Ebury Street has been closed to motor traffic - only bicycle traffic (and pedestrians) can exit here. You even get a cycle-only stage on the lights, allowing you to sail through this large, horrible junction in complete isolation. But you can't turn right. Or go straight ahead. These are one-way roads. And the whole area is awful and unpleasant!
But this is a small bit that's been done right.
