Routine design When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art. The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.

The stoop is a space of spectatorship Along with being a meeting place, the stoop is a space of spectatorship. A street lined with stoops is a kind of lateral stadium, ideal for viewing the passing parade, whether formal ones like the giant Gay Pride and Halloween Parades (until their route was changed a few years ago) or the more informal quotidian version. Hanging out on the stoop allows the sitter to observe the dance (Jane Jacobs’s ballet) of daily activity, to notice what is out of the ordinary, to provide the kind of public presence that prompts neighborly behavior.
