Recently National Public Radio had a news story about a section of Buenos Aires that decided on a different kind of book fair. Bookstores along the seven blocks of Corrientes Ave. closed off the streets in the summer, set up chairs, tables, and sofas and celebrated books and literature. While we tend to think of ciclovias as being for bicycles, any type of outdoor activity will do.
In Portand they have even incorporated a street festival design into an actual street. Not only does Davis Street include barriers to block off the roadway to traffic by using large granite blocks; but the design also includes movable barriers as well.
When you look at the overhead view below you noticed that they even did away with the traditional street design. No white line down the middle of the street, in fact the street surface is more like a dance floor than a roadway.
It would be great if other Bay Area cities could incorporate this type of design into their streets as well. I am looking forward to the day when a Bay Area city south of San Francisco steps up to the plate and organizes their own ciclovia as well.
