1. An adjustable mold system for making precast concrete traffic barrier panels with different geometries for creating a continuous traffic barrier by placing the traffic barrier panels in a contiguous side-by-side arrangement adjacent a roadway atop a modular earth retaining wall, each traffic barrier panel having a body with at least front, back, top, bottom, left, and right sides, the mold system comprising:
a mold body having a plurality of walls that define an interior chamber, a door opening to the interior chamber, and a concrete inlet to the interior chamber;
a plurality of available interchangeable doors, each door designed to be installed on and uninstalled from the mold body to respectively close and open the door opening, each door having forming panels, the forming panels designed to define a two-dimensional geometry at each of the left and right sides, each door designed to define a traffic barrier panel that is different than other doors; and
wherein the interior chamber of the mold body in combination with a particular interchangeable door from the plurality installed on the mold body define an outer surface of the front, back, top, bottom, and left and right sides of the particular traffic barrier panel to be made.
