A method for creating working space for construction of a new high-voltage transmission line within an existing three phase high voltage transmission right of way without removing the existing three-phase high voltage transmission line already occupying that right of way from service. The method includes removing the voltage applied to one phase of the existing transmission line, continuing to transmit power on the conductors comprising the remaining phases, and installing new support structures and their associated conductors on the right of way while the existing transmission line continues to operate.
