closed taxiway marking

On a taxiway closed for operation, a closed marking shall be placed at least at each end of the taxiway, or the portion thereof closed. The markings for closed taxiways are yellow. When a taxiway, or a part thereof, is permanently closed, all normal taxiway markings shall be obliterated. Lighting on a closed taxiway shall not be operated, except for the purpose of maintenance. When an area is temporarily closed, frangible barriers, markings utilizing materials other than paint, or other suitable means may be used to identify the closed area.
