Abstract: The present invention relates to a two-level bridge which uses steel girders having an efficient structural cross-section to form a space truss, thereby having structural stability in which long-spanning is possible, and creating a beautiful appearance. The bridge having a two-level structure formed of a pair of outer lower roads and a central upper road is characterized in that a pair of outer lower roads has completely divided in crossing methods; each of the outer lower roads is supported by an outer steel pipe girder comprising of one steel pipe; the central upper road is supported by an upper steel pipe girder comprising of two steel pipes parallel to one another and a horizontal beam connecting the two steel pipes; a central steel pipe girder comprising of one steel pipe is positioned between the two outer steel pipe girders, wherein the two outer steel pipe girders and the central steel pipe girder are positioned on the same plane throughout the whole length of the bridge; a side member is provided between the upper steel pipe girder and the central steel pipe girder to form a space truss having an inverted triangular cross-section, and the upper steel pipe girder and the central steel pipe girder are buried together in an end-concrete box on a same plane at both ends in the longitudinal direction to form a hollow core slab girder; and the pair of outer steel pipe girders and the central steel pipe girder are buried in a tie beam installed at predetermined intervals to be integrated with one another.
