International Organization for Standardization has circulated proposal for new field of activity on location requirements of urban pedestrian bridge assemblies in cities. A pedestrian bridge or "footbridge" is an elevated structure designed to facilitate safe access for pedestrians as they cross from one side of a traffic-heavy road or highway to the other. As the U.S. member body to ISO, ANSI invites all interested stakeholders to submit comments on proposal by March 25, 2016.
