Closer to the City Hall it is just striped and equipped with bike-specific signals. Note the back-in angle parking on the far side, a nice way to orient parked cars so drivers have a direct view of cyclists as they prepare to pull out. It looks like the parking access lane runs opposite the main traffic flow, which seems odd to me but I’m glad to see that the city is willing to try unique solutions.

I didn’t go out of my way much to avoid the hills. In my limited explorations I didn’t find them to be insurmountable. I did see some electric bikes, too, a good strategy if you need it. Here’s a classy example, the Faraday, seen at Huckleberry Bikes on Market Street. Batteries concealed in the down tube, belt drive, integrated lights, fenders and a frame-mounted front rack. About $3500.
