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.

Locus. (Appwalls) An Article by Ethan Marcotte ethanmarcotte.com I’ve noticed a recent trend on the web — or at least, on the parts of it I’ve visited. Maybe you’ve noticed it too. Here’s what happens: you’re on a website, and one of these little prompts pops up...[to] let you know that there’s an app, and that the website you’re on...well, it’s not quite the app, is it? ...Sometimes, the website wants me to install the app — no, it needs me to install the app. It’s like a paywall, but for apps. An appwall. In recent years, these prompts have gotten more prominent, and occasionally impassable. And I think that trend’s interesting. Why would a company promote a native app over their perfectly usable website? It feels like a glimpse into that company’s design priorities. And it’s possibly providing us with insight into the business value they place on the open web — a medium that’s meant to be accessible everywhere, on any screen, on any device. And it really does feel like these glimpses are becoming more common. wwwux
