Here are 10 of the longest running construction projects.
Some large building projects are especially prone to delays and those can be caused by any number of circumstances. Others are just destined to drag on from the start.
Here are 10 of the longest running construction endeavors out there.
Number 10. La Sagrada Familia. Begun in 1882, the Barcelona cathedral has encountered a number of setbacks. After a falling out with the original architect, it was handed over to Antoni Gaudí and would become his masterpiece. Gaudí’s untimely death and a fire that destroyed all of his plans, drawings and sketches also slowed the process. Numerous architects have signed on to finish the job, and it’s believed the building will be complete in 2026.
Number 9. New York City Water Tunnel Number 3. If finished in 2021 as planned, the system upgrade will have been 51 years in the making. Once completed it will deliver over a billion gallons of water a day to about 9 million New York City residents.
Number 8. 2nd Avenue Subway. Officials of the Big Apple have been working on this rail line since the late 1920s. Estimates back then had it opening sometime between 1938 and 1941 and at a cost of 86 million dollars. Recent predictions see completion possibly occurring as early as 2018. The price of making it happen has gone up to 5.7 billion.
Number 7. South-North Water Diversion. The goal is to supply China’s arid northern areas with water drawn from the country’s southern reaches. The planning stage of the very ambitious project stretched on for 50 years, and it’s believed construction will take nearly as long. Work has been underway since 2002, and the estimated completion date is in 2050.
Number 6. Great Man-Made River Project. Libya is among the driest nations in the world, but thankfully while drilling for oil a very large water supply was found. Getting to it and piping it to where it’s needed is no small task. Finishing up the project, which was begun in 1984, will likely take another quarter of a century.
Number 5. Gotthard Base Tunnel. It’s understandable that what’s going to become the world’s longest train tunnel is taking a good amount of time to build. Further, making it happen requires digging a giant hole beneath the Alps that extends from Germany to Italy. Workers have already put in around 17 years but may have as little as 1-and-a-half more to go.
Number 4. The 10 Thousand Year Clock. Amazon-dot-com founder Jeff Bezos is spearheading the building of a clock that will run, as its name suggests, for 10 thousand years. There are no estimates as to when it will be up and ticking, but it’s not expected to be soon.
Number 3.California High Speed Train. On January 6th of 2015 ground was broken for what is the United States’ very first foray into bullet trains. It will eventually travel between San Francisco and Los Angeles, but don’t rush out and buy a ticket. The line isn’t expected to be operational until about 2029.
Number 2. Nuclear Fusion Reactors. The race is on to be the first entity to make a very compact energy source that can power tens of thousands of homes, but it’s not a very fast one. The need for such a thing was recognized many years ago, and those working to make it a fully functioning reality say they’re still at least 10 to 20 years away from doing so.
Number 1. UK’s High Speed 2 Rail Project. Upon its proposal in 2013, the anticipated timeline for the endeavor was 20 years. Included in that estimate were a number of possible delays, but it appears the project has already run into some unanticipated snags involving routes and funding approval.
Which long-enduring project would you most like to see finished?
这里有10个运行时间最长的建设项目。
一些大型建设项目特别容易延误和那些可以通过任意数量的情况引起的。其他人则只是注定从一开始就拖。
这里有10个运行时间最长的建设努力的在那里。
10号圣家堂。开始于1882年，在巴塞罗那大教堂遇到了一些挫折。经过闹翻与原来的建筑师，它被移交给安东尼高迪，并会成为他的代表作。高迪的英年早逝和大火摧毁了所有他的计划，图纸和草图也减慢的过程。许多建筑师都签署完成的作业，它认为建设将完成2026年。
数9.纽约市水洞号码3.如果在2021年按计划完成，系统升级将一直51年的决策。一旦完成，将提供超过十亿加仑的水每天约900万纽约市居民。
8号第二大道地铁。大苹果的官员一直在这条铁路线上自20世纪20年代后期。估计当时有它的1938年和1941年，并在8600万美元的成本打开某个时候。最近的预测看完成可能发生，早在2018年促成这件事情已经上升到5.7十亿的价格。
7号南水北调引水。我们的目标是向中国供应的北方干旱地区的水从该国南部达到绘制。非常雄心勃勃的项目的规划阶段就捉襟见肘了50年，它认为建设将需要近等长。自2002年以来的工作一直在进行中，并预计竣工日期为2050年。
6号大人工河项目。利比亚是最干旱的国家，在世界前列，但幸运的是，同时开采石油非常大的供水被发现。得到它，并输送至需要的地方是个不小的任务。完成了该项目，该项目始于1984年，将有可能采取另一种四分之一个世纪。
5号哥达基线隧道。这是可以理解的，这是怎么回事，成为世界上最长的铁路隧道，走的时间来建立一个良好的金额。此外，促成这件事情，需要挖掘，从德国扩展到意大利阿尔卑斯山的下面一个巨大的洞。工人已经投入约17年，但可能低至1和半多了去了。
数4. 10千年时钟。亚马逊的dot-com创始人杰夫·贝索斯带头时钟将运行的建设，正如它的名字所暗示的，用于万年。有没有估计何时会启动并滴答，但它预计不会很快。
一些3.California高速列车。在2015年地面1月6日被打破，什么是美国“非常首次涉足子弹头列车。这将旧金山和洛杉矶之间的最终旅行，但不要急于掏钱买了票。该行预计不会投入运营，直到大约2029。
号码2的核聚变反应堆。这场比赛是要作出这样可省电家园数万非常紧凑能源的第一个实体，但它不是一个非常快的。需要这样的事情被认定多年前，而那些工作，使之成为全功能的现实说，他们至少还要10到20年的时间这样做。
号码1.英国高速铁路2项目。根据其在2013年的建议，预期时间表的努力是20年。包括在该估计是一些可能的延迟，但它似乎该项目已经开到了一些涉及路线和资金审批意想不到的障碍。
