37 Miss. Code R. § 1-7501-04015-407
No utility poles or other above ground supports for overhead crossings may be placed in the medians as a part of utility highway crossings unless, in each case, a determination is made by the Chief Engineer that without such pole or support located in the median, the line would be (1) extremely difficult and unreasonably costly to the utility consumer, (2) the installation in the median will not adversely affect to a substantial degree the design, construction, stability, traffic safety or operation of the highway and (3) that in case the highway is designated as a fully or partially controlled access facility every practicable provision will be made for servicing the utility without access from the through traffic lanes or ramps, including removal to a new location.
