Pedestrian Bridges
A pedestrian separation structure is any structure that removes pedestrians from a vehicle roadway. This creates a road junction where vehicles and pedestrians do not interact.
This can be considered a type of grade separation structure on the road.
These structures can be located either above the roadway or below the roadway. In the U.S., access under the Americans with Disabilities Act requirements means that stairs cannot be the only access to these structures. An elevator must be provided or a ramp built that conforms to the grade requirements under the ADA regulations.
In the broadest sense, building codes that limit the number of driveways that cross sidewalks may be viewed as making the sidewalks a separation structure.
In many areas, wildlife crossings are provided in wilderness areas to allow wildlife to cross roadways without risking accidents. While not specifically built for people, they could be used by people in those areas.
Famous quotes containing the words pedestrian and/or bridges:
“However global I strove to become in my thinking over the past twenty years, my sons kept me rooted to an utterly pedestrian view, intimately involved with the most inspiring and fractious passages in human development. However unconsciously by now, motherhood informs every thought I have, influencing everything I do. More than any other part of my life, being a mother taught me what it means to be human.”
—Mary Kay Blakely (20th century)
“We live technologically, with man as the master of nature, man as the engineer, and let anyone who raises his voice against it stop using bridges not built by nature.... No electric light bulbs, no engines, no atomic energy, no calculating machines, no anaesthetics—back to the jungle.”
—Max Frisch (1911–1991)
