§ 10.16.030. Reduced speed zones for detour routes.
Whenever a portion of a county highway is being used or is about to be used as a detour route under a reconstruction project of a highway and the director of transportation determines that the existing speed limit upon such highway is more than reasonable and safe because of increased vehicular traffic and a reduced speed zone is warranted and necessary, he or she may temporarily fix such appropriate lower rate as provided in Section 22358 of the California Vehicle Code which will facilitate the orderly movement of traffic and will be reasonable and safe upon that portion of the highway for the period the highway is used as a detour route. Thereupon the prima facie speed limit so fixed shall be effective during the period appropriate signs are erected and maintained along that portion of the highway by the director of transportation.
