What is a "road in lieu"? What defines the boundaries of such a road?
I'm sorry, but "road in lieu" is not a commonly used term or concept that I am aware of. It might be a term specific to a certain region, jurisdiction, or industry. Without more context or specific information, it is difficult to provide a clear definition or explanation of what a "road in lieu" might refer to.
However, in general terms, a road is a public or private thoroughfare that allows transportation between two points. The boundaries of a road are typically defined by the physical features surrounding it, such as sidewalks, curbs, street signs, or other infrastructure. Specific legal or jurisdictional regulations may also determine the width, alignment, and other characteristics of a road.
If you can provide additional details or clarify the context in which you encountered the term "road in lieu," I may be able to assist you further.
