ABSTRACT OF THE DISCLOSURE An adjustable mold for casting asymmetric concrete highway divider sections includes a fixed sidewall, a movable sidewall, and two end walls. Each of the end walls is divided vertically into a first fixed panel and a second adjustable panel. The mold can be set up to produce a barrier section that accommodates any difference in grade levels between the separated roadway lanes, within a preselected range, by adjusting the height of each second end panel relative to the adjacent first end panel and by adjusting the height of the movable sidewall to match the second end panels. All adjustments are made by means of simple jack screws. The end walls and the movable sidewall are mounted on hinged frames that can be swung open to facilitate removing a section casting from the mold.
