It's great to see the people in New York enjoying being able to walk above the streets:
BBC News - Millions stroll in New York's 'park in the sky'
The high walks in the City of London provide a similar escape from the dirty traffic filled streets. It's unfortunate that here in London the high walks are being systematically closed and demolished at the hands of the City of London chief planning officer, Peter Rees. I attended a planning meeting where he seemed to take enormous pleasure in supporting a project which depletes the high walk even more. He joked about the people who use the high walks in a most demeaning way.
Perhaps he should have a look at how New York is recognising the value of pedestrian spaces away from traffic, and look to projects which improve rather than diminish the lived-in environment.
