To provide various structural devices for realizing a grade separation land bridge constructible on a simple foundation in an extremely short period, since a work period becomes long and work cost becomes expensive, when constructing a foundation structure for a pier of the grade separation land bridge, when installing the grade separation land bridge.
This steel grade separation land bridge 1 has a central clear span structure 2 and an approach part structure 3. The approach part structure 3 has a plurality of approach part blocks 4 divided into a plurality in at least the bridge axis direction. Since the respective approach part blocks 4 have a pair of base structures 5 continuously arranged on the ground surface in two rows in parallel to the bridge axis direction in a plan view, a foundation can be simplified and omitted by reducing bearing pressure by sufficiently largely securing the contact area with the ground surface of the base structures 5.
