More Bridges, More Flackery

Because I can: here's another Wired story I can flack. Writer David Goldenberg collects half a dozen examples of supercool, high-tech bridges in the latest issue. When Chris or Abhijeet teach me how to upload pics with our new software, I'll put a couple here. Meanwhile, the story's online. Salient bits: Today, an explosion of new designs and materials is creating a third golden age of bridge building. Cable-stays transfer the load on the roadway to towers via radiating wires. Electromagnetic dampers and giant underwater shock absorbers resist the kinetic energy of wind, quakes, and collisions. Sensors - fiber-optic cables, digital cameras, and accelerometers - let engineers know how bridges are holding up in real time. And higher-performing steel, concrete, and carbon fiber-reinforced polymers are making spans lighter, stronger, longer, and taller.

David makes the point that by the 22nd century, five of the seven continents will be connected. Road trip!

I love the variety of courses, many practical, and all richly illustrated. They have inspired many ideas that I've applied in practice, and in my own teaching. Mary G., Urban Planner
