Bridges as walls The biographer of Robert Moses, Robert A. Caro, refers to the bridges and underpasses of the famed New York State parkways. These bridges and underpasses are quite low, intentionally specified by Moses to allow only private cars to pass. All those who traveled by bus because they were poor or black or both were barred from the use and enjoyment of the parkland and its "public amenities" by the technical design of the bridges. Even at the time of Robert Moses, a political statement of the form "We don't want them blacks in our parks" would have been unacceptable in New York State. But a technological expression of the same prejudice appeared to be all right. Of course, to the public the intent of the design became evident only after it was executed, and then the bridges were there. Ursula M.

A more spiritual place In the centre of the forest is the sandō, leading up to the shrine. It follows an L-shaped curve, and is very different to the straight processional pathways found in religious buildings in the West or in China. Curves ensure that the view changes constantly, helping visitors make the transition to a deeper, more spiritual place. Kengo Kuma, My Life as an Architect in Tokyo 112.
