From SFBC:
Come on this bike and walk survey of the area around the Cesar Chavez/Highway 101 intersection - commonly known as the Hairball - to come up with solutions for improving access. The Planning Department is planning improvements to this corridor in various stages from Sanchez Street to Illinois Street and has an initial set of improvements for this intersection. Join the SF Bicycle Coalition on-site to build upon these ideas and create a safe and comfortable connection to Caltrain, the Bay, and Mission, Bayview and Potrero Hill neighborhoods. See more information here and contact Neal@sfbike.org if you have any questions.
