Airspace in the highway right-of-way context means the vertical space within the area that the highway authority controls. This space can be used for other purposes, as long as those uses do not interfere with the safe operation of the highway. The agency can permit encroachments into this airspace—such as signs, overhangs, or utilities—only when safety, traffic operations, and sight distance are not compromised. That makes the correct definition the property located within the right-of-way that can be put to other uses without affecting how the highway functions.

Why the other ideas don’t fit: airspace refers to the portion above the ground within the right-of-way, not space outside the right-of-way; it isn’t about underground areas. And it isn’t about parcels that aren’t part of or related to the highway.
