milewide
milewide is a term used to describe something that is one mile in width. It is not a formal unit of measurement but rather a descriptive phrase. The concept of a milewide area can be applied to various geographical features or man-made structures. For example, a river might be described as a milewide at its widest point, or a large park could have a milewide expanse.
In some contexts, milewide can also refer to a broad, sweeping, or extensive area, not necessarily limited
The term is straightforward in its meaning and does not carry any complex historical or scientific connotations.
