The bridge was completed in 1997 by the Obayashi Corporation but I couldn't find out who designed it. It appears to be more of a folded shell structure rather than a typical arch bridge. The arch spans are about 35 m (115 ft) long with only about a 2.5 m (8 ft) rise and the deck is unsupported over the piers. It is an unusual design but a very attractive bridge.
