SDCL § 31-3-18: Width of highway.

Any public highway located under §§ 31-3-6 to 31-3-37, inclusive, shall be at least sixty-six feet in width, and may be one hundred feet in width if all residents of land adjoining the highway petition for such width. However, a highway not exceeding one-half mile in length and not located on any section line shall be at least thirty-three feet in width if, in the judgment of the board of county commissioners, such width is sufficient to accommodate properly the travel on the highway. Each order locating or changing any highway shall specify the width of the highway.
