Strait of Messina Bridge have made the span more than 60% longer than the Akashi-Kaikyo Bridge in Japan—the largest suspension bridge in the world at . Plans called for four traffic lanes (two driving lanes and one emergency lane in each direction), two railway tracks and two pedestrian lanes. In order to provide a minimum vertical clearance for navigation of , the height of the two towers was to be . This would have been taller than the Millau Viaduct in France (currently the tallest bridge in the world at ). The bridge's suspension system would have relied on two pairs of steel cables,
Orthotropic deck in the US are in California, including the San Mateo-Hayward Bridge, which is one of the first major bridges in the US to be built using an orthotropic deck. Some very large cable-supported bridges, plus current record span (cable-stayed bridges and suspension bridges) would not be feasible without steel orthotropic decks. The longest or record span box girder, slant-leg bridges; arch bridges; movable bridges and two Norwegian floating bridges all use orthotropic decks. The Millau Viaduct a cable-stayed bridge of Millau, France has the largest orthotropic steel deck area of any single bridge. The lower total gross weight of the
