Menlo Park has a few streets labeled local traffic only as well.

Palo Alto has quite a few as well. Some are just marked with signs, many have physical barriers allowing only bikes and large trash collection vehicles to easily pass.

  A fair stretch of Bryant St. is bike-limited, with narrow barriers every few blocks. I used it in my bike commute from Sunnyvale to Menlo (which also used pedestrian/bike bridges that cross the creeks that define the Mtn View / Palo Alto and Palo / Menlo borders).

  Is there an example of these? I'm having a hard time picturing how a barrier can allow bikes and large traffic to pass whilst blocking other traffic.

    There are barriers that restrict traffic based on dimensions - such as the 'bus trap' [1] that only allows wide vehicles, and the 'sump buster' [2] that only allows high-ground-clearance vehicles through. Of course, these have the disadvantage that (a) they damage the cars of confused motorists [6] (b) cars stuck in traps obstruct busses anyway[5], and (c) large SUVs and pick-up trucks can drive over them anyway [4]. Another option is a powered rising bollard [3] or barrier together with some mechanism (tag, ANPR, keypad) for recognising authorised vehicles. Which avoids a lot of those weaknesses - at the cost of power and maintenance.
