Just caught this photo on Streetsblog SF's Flickr pool.
More than just planters and chairs, the temporary pedestrian plaza at 17th and Market Streets will be (or is now, I should say) defined by yellow paint. Color and texture differences on the asphalt in similar trial plazas in New York - on which this space is modeled - have proven surprisingly successful in delineating the plazas as safe pedestrian space.
Streetsblog reports that the plaza will officially open on Wednesday morning with a press conference with our Spokesmayor. It's on our Important Dates in the sidebar in case you want to attend.
