State Scenic Highway System (California)
The State Scenic Highway System in the U.S. state of California is a list of highways, mainly state highways, that have been designated by the California Department of Transportation (Caltrans) as scenic highways. They are marked by the state flower, a California poppy, inside either a rectangle for state-maintained highways or a pentagon for county highways. The California State Legislature makes state highways eligible for designation as a scenic highway, listing them in the Streets and Highways Code, sections 260-284. For a highway to then be declared scenic by Caltrans, the local government with jurisdiction over abutting land must adopt a "scenic corridor protection program" that limits development, outdoor advertising, and earthmoving, and Caltrans must agree that it meets the criteria. The desire to create such a designation has at times been in conflict with the property rights of abutters, for example on State Route 174. Any county highway that is believed to have outs ...
