W. Va. Code § 54-1-7
If any company shall acquire land under the provisions of this chapter, and, in the construction and operation of its work of internal improvement, obstruct or impede the owner of residue of the tract of land from crossing the land so acquired, when such crossing is essential for the proper use of the remaining land of the owner, it shall permit the owner of the land to construct, maintain and use suitable crossings over the land so acquired. If such land shall have theretofore been cleared and fenced, or shall thereafter be cleared and fenced, the company shall construct and forever maintain suitable farm crossings to adequately serve the tract of land as a whole, and, if a railroad company, cattle guards and fences, on both sides of the lands condemned and appropriated.
