One embodiment of a system of the present disclosure can be implemented as follows. A modular block wall system includes a vertical passageway formed within the wall from a top surface of the wall to a bottom surface of the wall and a plurality of tieback rods adapted to be embedded into soil or rock and each having a proximal portion extending into the passageway. The system further includes at least one elongate member positioned within the vertical passageway directly adjacent the proximal portions of the tieback rods, wherein tensile forces imposed upon the tieback rods are transmitted to the at least one elongate member so as to distribute the tensile forces throughout a portion of the retaining wall. Other systems and methods are also provided.
