瓦斯科·达·伽马大桥，里斯本，葡萄牙

今天的图片展示的是葡萄牙的瓦斯科·达·伽马大桥，宛如一条流畅的线条，穿过里斯本的天际线。从近处看，它是一座带高架桥的斜拉桥，横跨里斯本万国公园的塔霍河。瓦斯科·达伽马大桥是欧洲第二长的桥，也是欧盟最长的桥，于1995年2月开工建设，旨在缓解里斯本四月二十五号大桥出现的交通拥堵情况，使葡萄牙南北之间的交通更加顺畅。该桥具有抗震性，可在地震中吸收晃动。由于桥面没有固定在桥塔上，因此可以纵向和横向移动。大桥于1998年3月29日落成通车，恰逢98世博会举行，这是为纪念瓦斯科·达·伽马发现从欧洲到印度的历史性海路500周年而举办的世界博览会。

Vasco da Gama Bridge, Lisbon, Portugal

This sleek structure is the Vasco da Gama Bridge, which appears to vanish into the horizon after crossing the Tagus River in Portugal. Stretching nearly 8 miles, it was Europe's longest bridge when it opened in 1998, built to ease traffic on Lisbon's 25 de Abril Bridge and make travel smoother between the north and south of Portugal. This cable-stayed bridge was designed to be earthquake and wind-resistant; its deck is not fixed to the pylons, and it can move both lengthwise and sideways. Its opening was perfectly timed for Expo 98, the World's Fair celebrating the 500th anniversary of Vasco da Gama's historic sea route discovery from Europe to India.
