R.I. Gen. Laws § 24-15-4
After holding a public hearing, the director, or the governing body of any municipality as to any scenic highway (including a state highway) within its borders, may apply to the board for, and the board itself may propose, the removal of a highway from the scenic highway system. The board shall thereupon approve or deny the removal of the highway from its designation as a scenic highway. Provided, however, that no application for removal of a highway or road, or portion thereof, from the scenic highways system, shall be approved unless the owners of a majority of the lineal lot frontage abutting the highway or road agree to the removal by filing an application with the director or governing municipal body, within the sixty (60) days immediately preceding the application, a written statement or statements agreeing to the removal.
