The bridge over Kearny Street leading from the Portsmouth Square Plaza in Chinatown  to the Chinese Cultural Center in the Hilton Hotel on the east side of street was an attempt to encourage pedestrian traffic and tie the two points together.   The bridge never succeeded and this feasibility study was an attempt by the Chinese Cultural Center to obtain funding to do something to enliven the bridge and encourage traffic.

San Francisco has implemented a new trend by converting selected parking spaces into urban parks with tables and chairs.  North Beach was a pilot area in 2010 and apparently was a success and it has expanded to Polk Street and Potrero Hill.  While a few parking spaces may be gone, it certainly makes the street more interesting for hanging out.
