The Melbourne Grove thing is a bit iffy. I actually think there may be a good case for closure as part of an area wide plan, but that's not really what's happened. Pressure was put on the council by a small number of people to close 'their' street, which disgracefully, the council responded to with their usual knee jerk approach. After a bit of consultation and some fairly strong opposition locally, they decided to pause it. They've now tagged it on to the Dulwich Village scheme in a way that feels a bit opportunistic, again with no reference to a wider East Dulwich area strategy. As such, I suspect there will be unintended consequences.
