A dust collecting apparatus of a road tunnel is provided to increase dust-removing speediness by installing the upper discharge duct on the upper part of the tunnel and by forcibly discharging the air flowed through an installation groove through a first venting fan of a first discharge box. A dust collecting apparatus for a road tunnel is composed of an installation groove(200) of a long hole long formed to the longitudinal direction of a tunnel(100) and formed with a predetermined depth; a first discharge box mounted with a first venting fan(310); a first connection duct(320) whose one end is combined on the upper part of the first discharge box and other end is combined on the rear end of the installation groove; an upper discharge duct(600) installed with a second dust collecting hole(610) at the side; a second discharge box installed with a second venting fan at the front; and a second connection duct for flowing the dust to the second discharge box. A lower installation plate(510) is fixed on the upper surface of the installation groove cover and vertically attached with supporting bars(500) with a regular interval. The upper discharge duct is long installed at an upper installation plate(520).
