How Deep Is a Telephone Pole Buried?

By Staff WriterLast Updated March 24, 2020

Telephone and utility poles are generally buried up to 10 percent of their length plus 2 feet. For a pole 45 feet in length, for example, 6.5 feet would be buried underground

Telephone and other utility poles may be made of concrete or various types of wood, including Douglas fir and Southern pines. The exact level at which the pole is buried varies to a certain degree on the type of terrain. For example, poles on a curve are generally buried slightly deeper than those on a straight stretch of ground. In practice, telephone and utility poles are generally buried about 6 feet underground and placed approximately 125 feet apart.
