We biked out to Doyle Drive on Saturday to watch the demolition of the entrance to the Golden Gate Bridge. The weather was fine and the views fascinating. Every CAT in the state seemed to be at work on the project, which CalTrans managed to accomplish in one weekend. People lined the fence watching the destruction. We were amazed that the heavy equipment sat atop the road they were destroying, backing away from the abyss as each giant chunk fell. We spent all day biking around the project, getting as close as we could to the barrier fences, and looking at the demolition from different angles. We saw one section fall, but it didn't make a big kaboom like I expected. More like a creaking "splumph," with lots of concrete dust flying.
