Plastic pillars have been installed at a San Francisco intersection where a 2-year-old girl was recently killed after being struck by a driver.

Members of the “Safe Street Rebel” group who placed the pillars at the intersection of 4th and Channel streets hope it will slow drivers down while making a right turn.

The group is a collective of neighbors and traffic safety activists across San Francisco who have put up unsanctioned installations often in response to a fatal pedestrian collision.

Sergio Quintana takes a closer look at the installations and why people who live and work in the neighborhood had mixed reactions to pillars.
