The present invention relates to a bridge construction method which combines a bottom plate in a cantilever form with an outer girder mounted on an end of a bridge in a width direction to mount the combined bottom plate on a bridge post or an abutment to secure work space and constructability. According to a proper embodiment of the present invention, the bridge construction method using a bottom plate-integrated outer girder comprises: (a) a step of making a PSC girder comprising an upper flange, a web, and a lower flange, having an I-shaped cross section, and including a tendon arranged in a longitudinal direction therein; (b) a step of forming an outer girder formed on an upper surface of the upper flange of the PSC girder, wherein an outer bottom plate is formed to protrude on both sides of the upper flange in a width direction; (c) a step of mounting the PSC girders on a middle portion of an upper portion of a span of a bridge post or an abutment except both ends in the width direction at regular intervals, and mounting the outer girder on both ends; (d) a step of installing a form or a precast deck on an upper portion of the PSC girder, and arranging a rebar on an upper portion of the form or the precast deck; and (e) a step of depositing concrete on the upper portion of the form or the precast deck to form a bottom plate. |
