The Lake Pontchartrain Causeway, once the world's longest bridge at just under 24 miles (39 kilometers), spans the huge lake near New Orleans, Louisiana. As long as it is, it is now the ninth-longest bridge in the world.
庞恰特雷恩湖堤道，曾经是世界上最长的桥梁，长度不到24英里(39公里)，横跨路易斯安那州新奥尔良附近的大湖。尽管它很长，但它现在是世界上第九长的桥梁。
A bridge is a useful tool that can connect distant points separated by water, marshland or difficult terrain. Whether traveled on foot or by car or rail, bridges are as essential for transporting goods and services as they are for cutting down the travel time between two distant points.
桥是一种有用的工具，可以连接被水、沼泽或复杂地形分开的遥远点。无论是步行、汽车还是火车，桥梁对于运输货物和服务都是必不可少的，因为它们缩短了两个遥远地点之间的旅行时间。
But bridges represent something else, too. Something far more difficult to quantify. Something perhaps best described as a feeling – the type of emotion just as likely to arise when viewing a famous of work of art. This sense of awe and beauty draws people to bridges not only for their utilitarian function, but as iconic points worth admiring in their surrounding landscapes. Think of San Francisco's Golden Gate Bridge, with its Art Deco towers rising out of the mist like cathedral spires. Or the majestic Tower Bridge that spans the river Thames in London.
但桥还代表着其他东西。这是很难量化的。也许最恰当的描述是一种感觉——这种情感类型就像欣赏一件著名的艺术作品时一样可能产生。这种敬畏和美感吸引人们来到桥梁上，不仅是因为桥梁的实用功能，还因为它是周围景观中值得欣赏的标志性点。想想旧金山的金门大桥，装饰艺术风格的塔楼像大教堂的塔尖一样从薄雾中升起。还有雄伟的横跨伦敦泰晤士河的塔桥。
Whether as part of one's daily commute or as a vital artery that keeps an economy moving, these bridges have something else in common: their incredible length. A testament to human ingenuity, here are 10 of the longest bridges in the world, connecting lives — and breaking records while doing it.
无论是作为人们日常通勤的一部分，还是保持经济运行的重要动脉，这些桥梁还有一个共同点:它们令人难以置信的长度。这里是世界上最长的10座桥梁，它们连接着生命，并在此过程中打破了记录，这是人类智慧的证明。

The Danyang-Kunshan Grand Bridge, the world's longest continuous bridge, was built in just four years to provide high-speed rail service across China.
丹阳-昆山大桥是世界上最长的连续桥梁，在短短四年时间内建成，为中国提供高铁服务。
The Danyang-Kunshan Grand Bridge in China is a marvel spanning more than 100 miles (165 kilometers), making it the longest bridge in the world. The bridge, which officially opened in June 2011, was built in just four years to provide high-speed rail service across China. The bridge spans a variety of obstacles, including several canals and lakes. The Danyang-Kunshan Grand Bridge cost a whopping $8.5 billion to construct but has been designed to withstand not only typhoons and magnitude 8 earthquakes, but also direct hits from naval vessels weighing up to 330,000 tons (300,000 metric tons).
中国的丹阳-昆山大桥横跨100多英里(165公里)，是世界上最长的桥梁。这座桥于2011年6月正式开放，仅用了四年时间就建成了，为中国各地提供高铁服务。这座桥跨越了各种障碍，包括几条运河和湖泊。丹阳-昆山大桥的建造成本高达85亿美元，但其设计不仅能抵御台风和8级地震，还能抵御重达33万吨(30万吨)海军舰艇的直接撞击。
The Changhua-Kaohsiung Viaduct in Taiwan is actually a series of connected bridges, built to enable the entire structure to handle the stress of an earthquake.
台湾的彰化-高雄高架桥实际上是由一系列相连的桥梁组成的，建造的目的是使整个结构能够承受地震的压力。
The world's second-longest bridge is the Changhua-Kaohsiung Viaduct in Taiwan. The viaduct, which is a bridge comprised of a series of smaller bridges, is part of Taiwan's High Speed Rail network and spans a length of 97 miles (157 kilometers). The Changhua-Kaohsiung Viaduct was specifically constructed as a series of connected bridges to better withstand most earthquakes. This is an important safety consideration because Taiwan is located at the junction of two tectonic plates — the Philippine Sea Plate and the Eurasian Plate — and as a result, has a higher frequency of seismic activity.
世界第二长的桥梁是台湾的彰化-高雄高架桥。这座高架桥由一系列小桥组成，是台湾高铁网络的一部分，全长97英里(157公里)。彰化-高雄高架桥是专门建造成一系列连接的桥梁，以更好地抵御大多数地震。这是一个重要的安全考虑，因为台湾位于两个构造板块——菲律宾海板块和欧亚板块——的交界处，因此地震活动频率较高。
Completed in 2010, this bridge is a part of the Beijing-Shanghai High-Speed Railway and is the third-longest bridge in the world.
这座桥于2010年完工，是京沪高速铁路的一部分，是世界上第三长的桥梁。
China's Cangde Grand Bridge is the third-longest bridge in the world. It measures 72 miles (116 kilometers) in length and is part of an important arterial railway that transports people to and from Beijing. As part of the Beijing-Shanghai High-Speed Railway, the Cangde Grand Bridge comprises part of a more massive bridge that may sound familiar: the Danyang-Kunshan Grand Bridge. Like other parts of the Beijing-Shanghai High-Speed Railway, the Cangde Grand Bridge is designed to withstand most seismic shifts.
中国的沧德大桥是世界上第三长的桥梁。它长72英里(116公里)，是往返北京的重要铁路干线的一部分。作为京沪高铁的一部分，沧德大桥是一座更大的大桥的一部分，听起来可能很熟悉:丹阳-昆山大桥。与京沪高铁的其他部分一样，沧德大桥的设计能够承受大多数地震变化。
The Tianjin Grand Bridge in China opened to rail traffic in 2011.
中国天津大桥于2011年开通轨道交通。
The location of the fourth-longest bridge in the world may come without surprise: China. To keep China's extensive high-speed rail system zooming along, saving commuters time on their journeys, a series of bridges allow the trains to skim over low-lying areas, water and other obstacles. The fourth-longest bridge is the Tianjin Grand Bridge located in Hebei, in Tianjin, China, which opened to rail traffic in 2011. Measuring 70 miles (113 kilometers) long, the Tianjin Grand Bridge is held up by a series of reinforced girders that weigh up to 860 tons (780 metric tons) each.
世界上第四长的桥梁坐落在中国，这可能不足为奇。为了保持中国庞大的高速铁路系统的高速运行，节省通勤者在旅途中的时间，一系列的桥梁使列车能够越过低洼地区、水域和其他障碍。世界上第四长的桥梁是位于中国天津河北的天津大桥，于2011年开通轨道交通。天津大桥长70英里(113公里)，由一系列重达860吨(780公吨)的加固大梁支撑。
The Weinan Weihe Grand Bridge in China is part of the Zhengzhou-Xi'an High-Speed Railway which connects Zhengzhou and Xi'an.
渭南渭河大桥是郑州至西安高速铁路的一部分，连接郑州和西安。
When the Weinan Weihe Grand Bridge in China was first opened to traffic in 2008, it held the title of 'longest bridge in the world' at approximately 49 miles (79 kilometers) in length. While it was eventually surpassed by the Danyang-Kunshan Grand Bridge, Cangde Grand Bridge and Tianjin Grand Bridge in China and the Changhua-Kaohsiung Viaduct in Taiwan, at the time it was an engineering feat marveled the world over. As part of the Zhengzhou-Xi'an High-Speed Railway system, it played a critical role by connecting the cities of Zhengzhou and Xi'an, crossing a number of rivers and significantly lessening commuting time.
当中国渭南渭河大桥于2008年首次通车时，它以大约49英里(79公里)的长度获得了“世界上最长的桥梁”的称号。虽然它最终被中国的丹阳-昆山大桥、沧德大桥和天津大桥以及台湾的彰化-高雄高架桥所超越，但在当时，它是一项举世惊叹的工程壮举。作为郑州-西安高铁系统的一部分，它通过连接郑州和西安的城市，跨越多条河流，大大缩短了通勤时间，发挥了关键作用。

The elevated Bang Na Expressway in Bangkok, Thailand, runs from the east of the country to the capital.
位于泰国曼谷的邦纳高架高速公路从该国东部通往首都。
The Bang Na Expressway in Thailand may be the seventh-longest bridge in the world, but it could probably hold a second title as the world's longest car bridge. While the first six-longest bridges in the world are used exclusively for high-speed rail, the Bang Na Expressway is a six-lane elevated highway with toll stations on each end. The Bang Na Expressway is 34 miles (55 kilometers) in length and allows drivers to zip across Bangkok without getting held up in the traffic of the Bang Na-Trat Highway (or National Highway route 34), which runs below it.
泰国邦那高速公路可能是世界上第七长的桥梁，但它可能会成为世界上最长的汽车桥。世界上最早的6条最长桥梁是专门用于高速铁路的，但邦纳高速公路是一条两端都有收费站的6车道高架公路。邦那高速公路长34英里(55公里)，司机可以在曼谷快速行驶，而不会被下面的邦那特高速公路(或34号国道)的交通阻塞。

The Beijing Grand Bridge, which officially opened in 2011, is 30 miles (48 kilometers) in length, which puts it in eighth place among the world's longest bridges. It was built to connect the Yangtze River Delta and the Bohai Economic Rim on China's Eastern coast; both regions require railway transportation to export their supplies of agricultural and natural resources.
北京大桥位于北京城南。这座桥是中国上榜的几座桥梁之一，和其他几座一样，它是京沪高速铁路系统的一部分。北京大桥于2011年正式通车，全长30英里(48公里)，在世界最长桥梁中排名第八。它的建设是为了连接中国东部沿海的长江三角洲和环渤海经济圈;这两个地区都需要铁路运输来出口农业和自然资源。
At an unspecified point in crossing the Lake Pontchartrain Causeway, drivers are unable to see the land on either side.
在穿越庞恰特雷恩湖堤道(Lake Pontchartrain Causeway)时，司机无法看到两边的陆地。
The Lake Pontchartrain Causeway in Louisiana is the only bridge in the United States to rank among the world's longest bridges. At nearly 24 miles (39 kilometers), this southern Louisiana bridge comes in at ninth on our list. The Lake Pontchartrain Causeway is actually comprised of two parallel bridges of nearly the same length, with the first bridge opening in 1956 and the second bridge in 1969. At an imprecise mark, motorists are usually not able to see land on either side of the bridge. The bridge is so long that it is recognized by the Guinness World Records as the 'longest bridge over water in the world (continuous),' and at its center there is a bascule (another name for drawbridge) that can raise to let ships pass.
路易斯安那州的庞恰特雷恩湖堤道是美国唯一一座跻身世界最长桥梁之列的桥梁。这座位于路易斯安那州南部的桥长近24英里(39公里)，在我们的榜单上排名第九。庞恰特雷恩湖堤道实际上由两座几乎相同长度的平行桥组成，第一座桥于1956年开通，第二座桥于1969年开通。在一个不精确的标记处，司机通常无法看到桥两侧的陆地。这座桥很长，被吉尼斯世界纪录认定为“世界上最长的水上桥(连续的)”，桥的中心有一座吊桥(吊桥的另一个名字)，可以升起来让船只通过。
Line 1 of the Wuhan Metro in China, which opened in 2004, includes two tracks and 32 rail stations along the length of its 23.5-mile (38-kilometer) route.
中国武汉地铁1号线于2004年开通，全长23.5英里(38公里)，包括两条轨道和32个火车站。
In the city of Wuhan in Hubei, China, there is an elevated metro rail line simply named 'Line 1.' Although this may seem like a rather inauspicious name, Line 1 is actually a world record holder. At 23.5 miles (38 kilometers) in length, Line 1 is not only the tenth-longest bridge, but also is one of the longest continuous metro viaducts in the world.
在中国湖北省武汉市，有一条高架地铁线路，简称“1号线”。虽然这听起来不太吉利，但一号线实际上是一项世界纪录保持者。1号线全长23.5英里(38公里)，不仅是世界上第十长的桥梁，也是世界上最长的连续地铁高架桥之一。
