The present invention relates to civil engineering and, more specifically, to an upper structure of a multi-box girder type bridge having a cross beam and a construction method thereof. Especially, the present invention provides the upper structure of a multi-box girder type bridge which is characterized by having a plurality of box members (100) and cross beams (140); and the construction method thereof. The box members (100) are arranged on a lower structure (200) of the bridge, formed into a box shape in which a hollow (100b) is formed on a longitudinal direction (arrow L) of the bridge, and joined to the bridge in the transverse direction (arrow W) to be integrally moved. The cross beams (140) are protruding from each box members (100) toward the transverse direction (arrow W) and arranged on the lower structure (200). |
