Abstract: A method for replacing an existing utility pole comprising a proximal section having a bottom end attached to the earth and a distal section having hardware mounted thereon. A principal object is to replace the existing utility pole without disturbing the hardware. A new pole section is attached to the earth. The distal section with the hardware intact thereon is severed from the proximal section. The distal section is then connected to project from the new pole section. The new pole section can have a length different from the proximal section, so that net distance of the hardware from the earth is changed. Preferably the new pole section is made of prestressed concrete and is hollow to accommodate a line therein between the distal section and the earth to provide positive grounding to the earth.
