PROBLEM TO BE SOLVED: To provide a firm retaining wall formation body in which columns and beams are connected almost vertically, a cavity is formed in the inside, and concrete, reinforcements, PC steel bars, or their combined materials are put therein and unified together. SOLUTION: In the retaining wall construction method for a widened road, a plurality of stages of concrete stacking blocks having buttresses connecting to at least the front walls are used. The gradient of slope of the front wall is 20%-substantially perpendicular posture. Concrete, reinforcements, or civil engineering materials of soil and sand, etc. are filled inside the buttresses. In the construction method, a plurality of pieces of concrete stacking blocks having beam-columns rising at a steep inclination from the front wall are stacked toward the front wall above from a specified stage while the inclination of the front wall is kept as it is, to form the beam-column in a substantially vertically connected state.
