This weekend's final Sunday Streets of the year was a big success despite the fog.

On Friday, Streetsblog reported Mayor Newsom's announcement that Sunday Streets will become a permanent event starting in 2010 "with more routes, longer hours, more San Francisco neighborhoods and more programs at each event."

Newsom's office is talking about having eight or nine Sunday Streets events next year, and it will likely be expanded to underserved neighborhoods like the Tenderloin and Western Addition and "loop around to the great lawn at City Hall as home base."

In addition to Sunday Streets and car-free Golden Gate Park on Sundays, there's also talk of turning San Francisco roads that aren't heavily used on the weekends into permanent closures on Sundays as well, leaving them as blank canvases for the community to organize their own activities.
