Notes:

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.
