PURPOSE: Provided is a method of constructing simple and continuous composite bridges, such as simple and continuous preflex composite bridges, prestressed concrete(PSC) composite bridges, steel box girder bridges, plate girder bridges, and long span truss bridges. CONSTITUTION: The method of constructing simple composite bridges comprises the steps of: providing first and second abutments; implanting a shape steel in a bridge seat portion of the first abutment; simply resting a beam on the first and second abutments; connecting the shape steel in the bridge seat portion to a lower flange of the beam; applying a connecting concrete to a portion ranging from an upper end of the first abutment to a neutral axis of the beam; lowering a support near the second abutment; applying a concrete to a portion ranging from an upper end of the connecting concrete to a bottom plate of the beam; applying a floor slab concrete to the beam; and lifting up the lowered support near the second abutment.
