The Yamatogawa Bridge is a three span continuous steel cable-stayed bridge that carries the Wangan Expressway across the Yamato River in Osaka. It is located about 5 km south of yesterday's Minato Bridge. It was built for the Hanshin Expressway Public Corporation in 1982 at a cost of 13.9 billion yen. It crosses the Yamato River at a very high skew and so it required a long main span of 355 m (1166 ft).
The Yamatogawa is an unusual looking cable-stayed bridge. The single pylon towers are not attached to the substructure and they support a single plane of only four cables. The steel box girders sit on hammerhead bent caps supported on steel pipe piles. The bridge carries two lanes of traffic in each direction.
