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.

Blueprints Blueprints lead to the making of things that are abstract, not always based on reality. Once something becomes abstract, it breeds disconnectedness — separation and the inability to connect with our surroundings. People buy houses from blueprints, but then don't like the actual house: "What on earth is this? I had no idea it was going to be like this...etc." Christopher Alexander, The Battle for the Life and Beauty of the Earth Maps and observationThe preliminary sketch makingdesign
