- Subway (underpass)
In the
United Kingdom and some Commonwealth countries (such asIndia ,Australia ,Canada ,Hong Kong , andSingapore ), the term subway normally refers to a specially constructed underpass forpedestrian s and/orcyclist s beneath a road or railway, allowing them to reach the other side in safety.The term is also used in the
United States , specifically by theCalifornia Department of Transportation , for a road undercrossing which is depressed [http://www.dot.ca.gov/ser/downloads/cultural/CalHwyPhotoIndex.pdf] [http://groups.google.com/group/misc.transport.road/msg/0edef8a59ff141f2] .Underground pedestrian passageways are less common in North American cities than in European cities of comparable size. They are constructed when it is necessary for pedestriansto cross a
railroad or alimited-access highway such as aninterstate highway ,and of course they appear at the exits from undergroundrapid transit system s,but one would be rarely built just to enable people to cross an ordinary city street. When they are built, the term "pedestrian underpass" is more likely to beused, since the word "subway" is usually used there to refer to rail-basedrapid transit system s suchasNew York Subway .External links
