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.

Hints towards a non-extractive economy An Article by Matt Webb interconnected.org There’s a movement called the circular economy which is about designing services that don’t include throwing things away. There is no “away.” A non-extractive economy is going to look very different to today’s economy. These points feel opposed somehow but they are part of the same movement: With CupClub, it’s all about infrastructure. With the battery-free Game Boy, it’s untethered from infrastructure: once manufactured, no nationwide electricity grid is required to play. We’ll need better tools to track and measure. There will be new patterns for new types of services. New technologies to build new products. New language. So it’s fascinating seeing the pieces gradually come together.
