Thanks to a flat tire, I found myself on the bus from Mill Valley to San Francisco yesterday (usually I take the ferry or bike all the way). It was the first time that I’d traveled over the Golden Gate Bridge since the demolition of the old Doyle Drive that connects the bridge to the Marina (and on to downtown San Francisco).

The project has a pretty cool interactive map on which you can see the work they’re doing, as well as archived webcams (click through a few days over last weekend during the demolition).

In the photo gallery I found this picture. The tunnel (bottom left) is new, but before it could be used (and accessible) they needed to remove the elevated roadway just above it. That all happened in just one weekend. There’s a lot of rubble there now!
