Traffic Calming

The northbound side of speed-plagued San Jose Avenue north of 280, a.k.a. the Bernal Cut, is getting a road diet and buffered bike lane that matches the geometry of the street's southbound side. SFMTA crews were out today, re-striping the road and installing plastic posts in the buffer zone.

The debate over whether San Francisco's streets should be wider and less safe just to accommodate fire trucks was aired publicly at a City Hall hearing yesterday. Livable streets advocates and Supervisor Scott Wiener, who called the hearing, challenged the SF Fire Department's insistence on wider roadways, particularly its recent eleventh-hour push to change street widths that were agreed upon years ago in redevelopments at Hunters Point Shipyard and Candlestick Point.

Update 4/10: The Planning Department posted an online survey where you can weigh in on the design proposal for upper Haight Street.

A new online map begins to show which San Francisco streets have the worst speeding problems, according to data from SFMTA engineering and traffic surveys. The map was created by Stephanie May, who works for the SF-based organization Urban Mapping and teaches cartography at SF State University and history at Stanford, according to her Twitter page.

The SFMTA extended the buffered bike lanes on Bayshore Boulevard earlier this month from Silver Avenue south to Paul Avenue, reducing four traffic lanes to two. The street now provides a calmer, safer bicycling link for Bayview residents all the way up to where Bayshore ends, at Cesar Chavez Street and the "Hairball" freeway interchange.

The SFMTA has installed bike lanes and speed bumps on Holloway Avenue between Beverly Street and Ashton Avenue, a stretch that serves as the main bicycling route connecting SF State University to City College's Ocean Campus and Balboa Park Station.

A road diet and buffered bike lane are finally coming to San Jose Avenue north of 280, a.k.a. the Bernal Cut, where neighbors have fought for traffic calming for years.

Western Cesar Chavez Street has been transformed after decades as a dangerous motor vehicle speedway that divided the Mission and Bernal Heights neighborhoods. City officials cut the ribbon today on a redesign of the street, nearly nine years after residents began pushing for safety improvements.

The Wiggle is set to become a calmer, safer, and greener route after proposals presented by the SFMTA yesterday, with improvements like raised crosswalks, bulb-outs with greenery, textured pavement, and a traffic diverter at Scott and Fell Streets.
