045-24 Wyo. Code R. § 24-6
(a) Parallel utility runs within Department rights-of-way by private parties are generally prohibited unless unusual hardship or extenuating circumstances make construction outside the right-of-way extremely difficult, costly, or impossible. Private party utilities are allowed to cross Department roadways when runs are installed to Department specifications.
(b) The Department shall consider permission for parallel encroachment for transmission line companies with condemnation authority (W.S. 1-26-814 ) if the encroachment does not otherwise interfere with right-of-way use for highway purposes. A special agreement is required specifying access rights for construction and maintenance, detailed alignment and grade information, specific construction procedures around Department structures, and provision for inspection when deemed necessary. Access to utility lines outside the right-of-way where a no-access line is maintained shall not be allowed, nor shall utility maintenance be done from highway rights-of-way.
