Abstract: The present invention relates to a temporary bridge using a girder without a road decking panel and a construction method thereof. According to the present invention, a girder includes an upper flange forming an upper side, two web parts extended downward from both transverse sides of the upper flange respectively, and two lower flanges combined with the bottom of the web parts different from each other to be placed at a lateral interval and forming a lower side, and the girder is combined in a transverse direction to form a temporary bridge. A plurality of transverse combination members are combined at a longitudinal interval with a side facing an outer side in a transverse direction of the web parts, at least one concave groove part is formed at a longitudinal interval by being cut out to be concave in an edge part in the transverse direction of the upper flange. When the girders are consecutively placed in a transverse direction, the pair of concave groove prats facing each other in the transverse direction are brought into contact to be connected with each other to form one single work hole, and the pair of transverse combination members combined with the web parts are made to be adjacent in the transverse direction, and, here, the size, position and shape of the concave groove part are made to be a size, position and shape with which a worker can connect the girders in a transverse direction by combining the pair of transverse combination members adjacent to each other in a transverse direction through bolts while stepping on the lower flanges after moving into the inside through the work hole. Since the work hole is covered with a cover, when the girders are consecutively placed in the transverse direction, the upper flanges become successive to each other such that wheels of a vehicle can be prevented from being separated, and also, as the work hole is covered with the cover, an upper part of the temporary bridge can be completed only through the girders without a road decking panel.
