An Energy-Efficient House Could Be Built From the Bay Bridge's Scraps

This winter, the $281 million demolition of the old eastern span of the San Francisco-Oakland Bay Bridge kicked into high gear. Over the next three years, workers will remove 58,209 tons of steel and 245,470 tons of concrete, sending much of the material off to be scrapped or recycled halfway around the world. But if Bay Area resident David Grieshaber has his way, at least one 132-foot section of this 1.97 mile span will remain as a rather unusual monument to the bridge's 78-year history.

The tech entrepreneur and architecture enthusiast has spent the last year and a half developing his ambitious plans for the Bay Bridge House, a mixed-use, energy-efficient space built almost entirely from the bridge's recycled parts. "It's a celebration of the history of this wonderful asset we had," Grieshaber says. And, he adds, "I've always wanted to build a really unique house."
