Which of the following is an example of an easement in gross?

An easement in gross is a specific type of easement that is not tied to any particular piece of land but instead benefits an individual or entity. This differs from easements that are appurtenant, which are linked to a specific property and generally benefit the owner of that property.

In the context of the given options, the scenario involving the utility company's right to access poles on private property is a clear example of an easement in gross. This easement allows the utility company to use the land for its operational needs without being associated with any residential or commercial parcel. The benefit goes to the utility company itself, which allows it to maintain and service its infrastructure without being tied to the ownership of the land being crossed.

The other examples provided describe easements that are appurtenant, meaning they benefit specific property owners. For instance, a shared driveway between adjacent homeowners is an easement tied to the properties involved, allowing those owners to access their homes. Similarly, the access road used by the public benefits local properties and citizens, and a shared garden implies a communal benefit linked to specific homeowners. These situations illustrate the characteristic of appurtenant easements, where the benefit is attached to ownership of the property rather than to a separate entity or individual.
