San Francisco Makes a Guerrilla Bike Lane Permanent

Since debuting this year, the anonymous San Francisco Municipal Transformation Authority has installed more than a half-dozen interventions in the city to protect cyclists, mainly in the form of orange cones that barricade bike lanes from cars.

Their goal is not just to reduce traffic accidents, but to put “pressure on the [San Francisco Municipal Transportation Agency] and public officials to make proactive, rapid, and substantive improvements in street safety,” they write on a new website. And the pressure might be working: The city has decided to keep one of the SFMTrA’s fortified lanes until it can build its own version.
