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.

A little act of hope A Fragment by Jeremy Keith adactio.com As I scroll down my “on this day” page, I come across more and more dead links that have been snapped off from the fabric of the web. If I stop and think about it, it can get quite dispiriting. Why bother making hyperlinks at all? It’s only a matter of time until those links break. In a sense, every hyperlink on the World Wide Web is little act of hope. Even though I know that when I link to something, it probably won’t last, I still harbour that hope. If hyperlinks are built on hope, and the web is made of hyperlinks, then in a way, the World Wide Web is quite literally made out of hope. I like that. And thus the heart will break hypermediahope
