Based on over 2,600 responses to a solicitation for ‘visions’ as to where the next subway lines and connectors should be built in San Francisco, a heat map of the most requested routes and corridors has been compiled by the Connect SF team.

Dominating the responses, both online and in pop-up survey stations, was the development of a subway line along the length of Geary Boulevard.

The other most frequently envisioned new lines and corridors included a north-west extension of the Central Subway and new lines tracking Lombard, Van Ness Avenue, Divisadero, 16th Street, Potrero, Ocean and 19th Avenue.

And while camouflaged by the lack of a discrete survey path, if all the individual lines were combined, an envisioned connector between San Francisco and Alameda to Oakland would glow a bright red.

The Connect SF team is slated to develop an official vision for the future development of San Francisco’s subway lines by the end of the year.
