Fukazawa arch culvert was constructed along the bottom of a steep gorge enabling the highway to cross it over the structure. The arch culvert carries a municipal road and a river inside. The outline of the structure is shown as follows; arch span : 30.0 m, rise/span ratio of arch : 1/2, length of arch culvert : 159.0 m. This arch culvert of the largest scale in Japan was structurally analyzed by FEM for multi-statically indeterminated structure with individual footing foundation. This report shows structural characteristics and constructional method of arch culvert. In order to design and construct this structure, prevention of thermal cracks in mass concrete, multi-statically indeterminated underground structure and limit state design for reinforced structure were examined.
