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 surprising effectiveness of writing and rewriting An Article by Matt Webb interconnected.org The act of writing the first draft creates new “essential data” that feeds the imagination and makes possible figuring out the second draft. Or: In your head, ideas expand until they max out “working memory” – and it’s only be externalising them in the written word that you have capacity to iterate them. Or: Good writing necessarily takes multiple edits, and the act of writing and act of rewriting are sufficiently different that performing both simultaneously is like rubbing your tummy and patting your head.
