荷蘭鹿特丹斜拉張橋－Erasmusbrug（Erasmus Bridge，膩稱Swan天鵝橋）-2007/8/4參訪

1996年建成的荷蘭鹿特丹市伊拉斯瑪斯橋（Erasmus Bridge），跨越馬斯河（Meuse River），是一座開啓式獨塔斜張橋。這座橋建在近海處，是從水路到鹿特丹市的必經之路。
主跨284.14米，邊跨73.69米。139米高的橋塔採用折線造型，一側16根拉索，最外側拉索長度達298米，邊跨用兩根集膠成束拉索。

橋塔的折線造型與兩側斜拉索的不對稱佈置形成完善的結構平衡感，突出了斜拉橋橋塔的強勁作用，是一座設計精美，具有雕塑感的斜拉橋。

1996年8月6日荷蘭郵政發行郵票一套3枚，其中1枚爲鹿特丹的伊拉斯瑪斯橋。
設計者Ben van Berkel.
Erasmusbrug ("Erasmus Bridge") is a cable stayed bridge across the Nieuwe Maas river, linking the northern and southern halves of the city of Rotterdam, Netherlands.
The Erasmusbrug was designed by Ben van Berkel and completed in 1996. The 808 metre long bridge has a 139 metre-high asymmetrical pylon, earning the bridge its nickname of "The Swan".
The southern span of the bridge has a 89 metre long bascule bridge for ships that cannot pass under the bridge. The bascule bridge is the largest and heaviest in West Europe and has the largest panel of its type in the world.
The bridge was officially opened by Queen Beatrix on September 6, 1996, having cost 165 million Dutch guilders (about 75 million euros) to construct. Shortly after the bridge opened to traffic in October 1996, it was discovered the bridge would swing under particularly strong wind conditions. To reduce the trembling, stronger shock dampeners were installed.
The bridge was featured in the 1998 Jackie Chan film Who Am I? In 2005 several planes flew underneath the bridge as part of the "Red Bull Air Race".
