Notwithstanding the provisions of any general, special or local law to the contrary, a county road entirely or partly constructed, reconstructed or improved at a location where no public highway theretofore existed, may be designated within a county by the board of supervisors of such county, on recommendation of the county executive, if any, or in any other case on recommendation of the county superintendent of highways, as a controlled-access highway, to and from which the owners or occupants of abutting property or any other person shall have no right of access either as pedestrians, as operators of vehicles or in any other capacity, excepting at junctions of such highways with other public highways, and also excepting as such access may be reserved by the deed or final order of condemnation describing the property which has been or which hereafter shall be acquired for the purpose of such controlled-access highway. Such county road designated as a controlled-access highway shall be subject in all other respects to the provisions of the vehicle and traffic law, and the highway law with relation to county roads.
