Same old Old Street, always changing

I see from Professor Tim Stonor's blog that there has been a conference about improving Old Street roundabout as an urban space.Mmmmmmm....
I lived very close to the Old Street roundabout from 1997 to 2004. It was great, but the thing I learned about it was that the Old Street roundabout is always being regenerated, in the same way that the Forth Bridge was always being repainted. I don’t think there was a single day during those seven years when some part of the transport infrastructure that meets there (and there is a huge amount of that) was not under repair/malfunctioning/being redisigned. And there is always something there that someone will think they can improve.
