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:
“Managing a tantrum involves nothing less than the formation of character. Even the parent’s capacity to cope well with conflict can improve with this experience. When a parent knows he is right and does not give in for the sake of temporary peace, everybody wins. The parent learns that denying some pleasure does not create a neurotic child and the child learns that she can survive momentary frustration.”
—Alicia F. Lieberman (20th century)
