24.2.3 Control of Access Fencing on Freeway

Control of access fence should be erected whenever it is necessary to prohibit unrestricted access to the through lanes by pedestrians, animals, and/or vehicles. The prohibition of access to the through lanes should be from private property, intercepted local roads, and unauthorized crossings from frontage roads to the through lanes.
Table 24-1
describes the types of fences that should be used for various conditions. Department standard designs should be used where applicable. Specially designed fences may be necessary in certain areas where sandstorms and snowstorms occur and where other special conditions exist. Control of Access fencing is constructed and maintained by the State.

Notes:
1. Where frontage roads are provided, control of access fence, when used, should be placed in the outer separation approximately halfway between the mainlanes and frontage roads and at least 30-ft from the edge of mainlane pavement. Where the control of access line is at the ROW line, the control of access fence may be located at the ROW line and will serve a dual function as a ROW fence.
