S.C. Code Ann. § 58-17-1340

A railroad corporation may alter the course of a highway or other way, other than a street in any incorporated city or town, for the purpose of facilitating the crossing of it by its road, or permitting its road to pass at the side thereof without crossing, upon obtaining a decree of the governing body of the county prescribing the manner and time of such alteration. The corporation shall pay all damages occasioned to private property by the alteration, as in the case of land taken for its road.
