In a paper title "Construction of Nagisa Bridge Hybrid System of Cable Stayed PC Bridge and Steel Suspension Bridge" (by Yuzuru Sato, et. al.) the bridge is described as "The structure of this bridge is a hybrid structure of cable-stayed prestressed concrete bridge and steel suspension bridge. It is the first application as this structure type of bridge in the world. Concrete girders near pylons are supported by stay cables. Steel girders are supported by suspension cables in the central part of the span. This is new type system for prestressed concrete bridges with longer span and has many structural features compared with ordinary cable-stayed bridge and suspension bridge." and makes comparison to Arnodin suspension bridges where cable stays are the primary support for part of the deck.
