Aerial View Lishui Bridge and West Hunan Scenery航拍澧水大桥与湘西美景

From this video's 1:20-3:30 ,we can see at first drive through 856m span, 330m high Lishui bridge, then is Lishui bridge and nearby gorge's aerial. Now we can find Lishui bridge in fact as beautiful as nearby famous Aizhai bridge, even something more: Lishui river beneath this bridge is crystal clear and roaring waves, but there almost no water under the Aizhai bridge. Even the size of Lishui bridge no less than Aizhai bridge: Aizhai bridge's 1176m span is relatively exaggerated, it's two towers all located on mountains,the distance between two end of Aizhai bridge only slightly more than 900m. For most suspension bridges including Lishui bridge, total length much more than it's main span, so in fact Lishui bridge is almost the same size with Aizhai bridge. At about 0:53s we can see Furongzhen bridge in Yongshun to Jishou expressway. 230m span,140m high beam ,it's one of three large bridges in this new expressway. Last part of this video focus on peaks in Zhangjiajie national park. 从这段航拍视频中约1分20秒到3分30秒，可以看到先是开车路过张花高速澧水大桥，接下来是航拍这座主跨达856米，桥面高达330米的大桥及上下游澧水河谷。从航拍中能看出，澧水大桥风景绝不比邻近的矮寨大桥差，甚至还有优势：桥下的河水清澈见底，水势浩大。矮寨大桥桥下基本是干的。其规模也不比矮寨大桥小，矮寨大桥1176米主跨是灌水的，因为其桥塔建在山上，两端桥台之间的距离只有900米左右，而一般悬索桥桥台之间距离都比主跨大得多，包括这座澧水大桥，因此矮寨大桥实际建设规模不及四渡河大桥，和这座澧水大桥差不多。这段视频是唯一能从侧面看到澧水大桥全高的航拍，终于揭开其不为人知的神秘面纱。(因此桥没有游客，既不收费，也无看守，可随意下到刚桁梁中施工通道游玩，施工通道底部是百叶窗形式的垂直钢叶片构成，钢片很薄中间空隙很宽，几乎完全透明，可以悬空观赏下面330米深碧波荡漾的澧水河谷，想在施工通道玩多久都可以！去年我就在施工通道里转了几小时。矮寨大桥为旅游开发把施工通道改造成观光通道，既收费很贵，又在底部铺了不透明的地板，两侧都有铁丝网防止手机掉落，一点意思都没有。) 除澧水大桥外，约53秒处能看到主跨230米，高140米的芙蓉镇大桥，位于在建的永顺到吉首公路，是该高速公路三大桥之一，横跨酉水。末尾是张家界国家公园的峰林。 http://www.highestbridges.com/wiki/index.php?title=Lishuihe_Bridge http://www.highestbridges.com/wiki/index.php?title=Furongzhen_Bridge
