Disclosed are struts for a road soundproof wall and a soundproof tunnel. According to an embodiment of the present invention, the struts for a road soundproof wall and a soundproof tunnel comprise: a plurality of struts installed on the ground at predetermined intervals; and a plurality of soundproof panels which have both sides coupled to the struts and are installed in a vertical direction to have a soundproof function. Each of the struts includes: a strut flange which is formed to protrude from an outer circumferential surface, and on which one side of the soundproof panels is closely supported; and a strut fixture having a first support unit of which one surface comes in close contact with the outer surfaces of the struts, a second support unit which is formed perpendicular to the first support unit and is supported on the outer surface of a vertical frame of the soundproof panels, and a third support unit which is formed perpendicular to an end of the second support unit and is supported on the inner surface of the vertical frame of the soundproof panels. Accordingly, a rubber gasket and a rubber pad are attached to front and rear fixtures between layered soundproof plate and structure pillar to enhance adhesion so as to prevent leakage of noise and improve noise transmission loss of a soundproof wall.;COPYRIGHT KIPO 2020
