Temporary Markers
Pylons are sometimes used to separate HOV lanes from regular traffic lanes. They are also used in areas where lanes are used at different times for travel in both directions. These pylons have shafts that drop into holes in the road surface. A good example of this type of use is the Golden Gate Bridge in San Francisco.

Famous quotes containing the word temporary:
“The great attraction of fashion is that it diverted attention from the insoluble problems of beauty and provided an easy way—which money could buy ... to a simply stated, easily reproduced ideal of beauty, however temporary that ideal.”
—Theodore Zeldin (b. 1923)
