2019-10-10 06:45來(lái)源：深圳新聞網(wǎng)

武漢楊泗港長(cháng)江大橋（9月25日無(wú)人機拍攝）。

楊泗港大橋建設創(chuàng )造了多項世界之最：一是主橋跨度達1700米，為世界上跨度最大的雙層懸索橋；二是主橋設置雙層雙向12車(chē)道，是世界上通行能力最大的公路橋梁；三是大橋主纜設計張力6.5萬(wàn)噸，采用了世界上強度等級最高的主纜鋼絲；四是大橋設置機動(dòng)車(chē)道、非機動(dòng)車(chē)道、人行觀(guān)光道，集過(guò)江交通與觀(guān)光于一體，是長(cháng)江上功能最完備的橋梁。新華社記者熊琦攝
