London Bridge横架于泰晤士河之上,建于1886-1894年间,河心的两座主桥基高7.6米,在桥基之上是两座5层的高塔,两塔的距离为76米,塔顶之上还有尖塔耸立着,非常壮观吧牎更漂亮的是,附近的古城堡在河水中的倒影和塔桥交相辉映,成了泰晤士河上的一道美景。
  这是泰晤士河上诸多桥梁中,位于最下游的一座。塔桥以两座塔做为基底,采用哥特式厚重风格设计。当大型船只要通过时,全长270公尺、重约1000吨的桥身会慢慢打开成"八"字状。以前塔桥利用水压以蒸汽做为开关的动力,1976年起改用电动控制。位于伦敦塔旁,距西敏寺不远,是伦敦标志式的建筑物,于1894年建成通车,屹立于泰晤士河上,已有近百年历史,外形十分典雅,结构形式也与众不同,颇具气势。塔桥的桥身分上下两层,下层桥可以两面张开,每天开放两次让船只通过。两边有两座哥德式样的尖塔建筑,塔顶由大小五座小尖塔组成,颇有童话古堡的色彩。游人可以进入塔里参观,乘古老升降机登上塔顶,内里设有专馆介绍塔桥的建造;游人并可于上层的桥上鸟瞰伦敦市沿河两岸的景色。
伦敦塔桥的双塔是伦敦市内最著名的景点之一。这座桥建于19世纪90年代,1894年开放使用。
  像其他桥一样,伦敦塔桥包括一条公路以及公路上方的步行道。但与众不同的是。它的公路桥可以开启,以便高桅船能够驶入伦敦市。可惜现在已没有太多的高桅船保存下来了,塔桥每周只需开启几次。塔桥刚竣工时,第一个月便开启了600次。
塔楼内部设有若干房间。
  1894年6月30日对公众开放,将伦敦南北区连接成整体。河心建有两墩,相距76m,墩上建有高耸的方形尖塔,在两塔间建成一跨双层两用桥。下层是活动桥,6车道桥面,可通行万吨海轮;上层(高出水面43m处)为固定的人行桥。桥塔内设楼梯上下,内设博物馆、展览厅、商店、酒吧等。登塔远眺,可尽情欣赏泰晤士河上下游十里风光。

  塔桥高高耸立在泰晤士河上,河中的两座桥基高7.6米,桥基上建有两座主塔,为花岗岩和钢铁结构的方形五层塔,高40多米,两座主塔上建有白色大理石屋顶和5个小尖塔,远看仿佛两顶皇冠。两塔之间的跨度为60多米,塔基和两岸用钢缆吊桥相连。桥身分为上下两层,上层为宽阔的悬空人行道,两侧装有玻璃窗,行人从桥上通过,可以饱览泰晤士河两岸的美丽风光;下层可供车辆通行,并且可以开合。当泰晤士河上有万吨船只通过时,主塔内的机器启动,桥身慢慢分开,向上折起,船只过后,桥身再慢慢里落下,恢复车辆通行。两块活动桥面各重达1000吨。
  伦敦塔桥的设计颇为合理,在世界桥梁建筑业中有口皆碑。两岸两座用花岗石和钢铁建成的高塔,高约60米,分上下两层。上层支撑着两岸的塔,下层桥面可让行人通过,也可供车辆穿行。如果巨轮鸣笛而来,下层桥面能够自动往两边翘起,此时行人可改道从上层通过。桥内设有商店、酒吧,即使在雨雪天,行人也能在桥中购物、聊天或凭栏眺望两岸风光。
  从外表来看,塔桥的两端是维多利亚时代的砖石塔,但实际上塔身的结构主要是钢铁的。里面装有用来开合各重1000吨桥梁的水力机械。塔桥自建成至今,机械功能一直正常,从未发生故障。巨轮鸣笛致意后,上升机械只需一分钟便能使桥面升起。
塔桥的设计是为了同时满足航运和路面交通两方面的需要。塔桥博物馆工作人员解释说,当时所有的桥都建在塔桥的西面,维多利亚中期随着贸易的发展伦敦开始向东扩展,考虑要再建一座桥缓解交通,但码头老板反对,认为桥会阻止他们船只通过,讨论了多年终于建成了
塔桥,她张开桥面时可以让大船通过,而水平的桥面又利于马车的行走。可以翻转的每半个桥面的重量都在1000吨以上。塔桥从1895年全面投入使用以来桥面一共张开过6000多次,平均每星期张开十次。塔桥需要25个人负责它的操作和维护。负责人帕特森说,打开桥面需要五个人,控制室里有一个人,另外四个人在外面监控路面情况。
  建于1894年,有"伦敦正门"之称。塔桥两端由4座石塔连接, 两座主塔高35米,方正厚重,风格古朴,远望如两顶皇冠,雄奇壮伟。

UNDATED: In this handout image from London 2012 Ltd the design of London's first new Olympic venue is seen, revealing a state-of-the-art Aquatics Centre with a spectacular roof.The new venue - which will be built even if London is not selected to host the 2012 Olympic Games and Paralympic Games - marks the first stage of London's ambitious plans for the regeneration of a 500-acre site in Stratford, east London. The dramatic S-shaped roof of the winning design is inspired by the flow of water, reflecting the building's purpose and riverside location in the Lower Lea Valley. London is bidding to be the host city for the 2012 Olympic Games and Paralympic Games. (Photo by London 2012 via Getty Images)
