Demarcation of highway boundaries

(1) The Highway Authority shall have the boundaries of the highway in its charge demarcated with reference to the authoritative plans maintained by it, by planting stones or other suitable marks of a durable nature at intervals all along the highway in such a manner that the imaginary line joining such stones or marks shows the road boundary correctly. (2) Where there are bends or kinks in the road boundary, the stones or marks shall be so located as to have the correct configuration of the boundary if they are joined by straight lines.
