The connection from the Panhandle to Golden Gate Park is a bit complicated. Before the western edge of the Panhandle, bikes veer off the path to the right at Shrader Street. The bike light at Shrader Street directs you into a marked bike lane on Fell Street, which in turn leads to the protected bike lanes of Golden Gate Park. The turn is called the Shrader Valve.
Starting from Market Street at the Ferry Building, through the Wiggle to the Panhandle, and through the Shrader Valve to Golden Gate Park, you can ride a bike in marked lanes on a relatively flat route from San Francisco Bay at the eastern edge of the city to Ocean Beach at the western edge, and back again.
I finally got a picture of the Shrader Valve intersection this afternoon on the way home from Western Addition Sunday Streets. It’s not just for tires anymore!
