The Minato Bridge is a double-deck cantilever truss bridge in Osaka, Japan; upper deck is for Hanshin Expressway Route 16 Osakako Line, and lower deck is Route 5 Bayshore Line. It opened in 1974. It is the third-longest cantilever truss span in the world, behind the Quebec Bridge and the Forth Bridge.[2]

Designs including arch and suspension elements were eliminated from consideration due to poor subsoil conditions of alternating layers of clay and gravel. Instead, the designers selected a cantilever structure using high-strength steel, to reduce mass.[2]
