Gateshead Millennium Bridge 千禧橋 - 轉載 -

這座位於New Castle的Gateshead Millennium Bridge 是當初英國為迎接千禧年所進行的眾多重大工程之一，

它也是可以開啟的橋，但開啟方式非常特殊。

橋面從烏瞰來看是一道弧形，另外還有一道垂直的弧形鋼架，很多鋼索則聯擊這兩道弧形，複雜的張力結構維持橋的穩定。

總之兩道弧形都轉到空中，就有足夠的空間讓船通過。

千禧橋

造價 £22,000,000 英鎊

總重 850 tons

高 50 m (拱頂點)

寬 126 m (弧形橋面最凸出處與拱的頂點的水平距離)

橋面升起開啟需時 270 秒
