魔法之河深不见底 Enchanted waters run deep

斯利加坎老桥，苏格兰斯凯岛

迷人的苏格兰斯凯岛上有一座斯利加坎老桥，在19世纪初，才华横溢的苏格兰土木工程师托马斯·特尔福德设计并建造了这座桥梁。桥拱横跨斯利加坎河，桥面仅供骑行者和行人通过，在河流下游有一座现代桥梁用于汽车通行。站在桥面那饱经风霜、朴素且长满青苔的石头上，游客可以眺望远处雄伟的库林山脉。根据当地的传说，斯利加坎河中蕴含着仙女赐予的神秘祝福，而那些敢于将脸浸入河水中的人，则会获得永久的美貌。

Sligachan Old Bridge, Isle of Skye, Scotland

The enchanting Isle of Skye in Scotland is home to the Sligachan Old Bridge, built by Thomas Telford, a prolific Scottish civil engineer, in the early 1800s. The bridge arches over a river of the same name, and carries only cyclists and pedestrians, while a modern bridge downstream serves cars. From atop the bridge's weathered, mossy stones, travelers can take in the majestic Cuillin Mountains in the distance. According to local tradition, the Sligachan River's water contains a mysterious blessing provided by fairies. Those who dare to immerse their faces in these waters are said to be gifted with timeless beauty.

一条用桁架架起来的公路 A road you can truss

阿斯托里亚-梅格勒大桥，俄勒冈州

1805年，梅里韦瑟·刘易斯和威廉·克拉克从圣路易斯附近出发，开始了他们传奇的北美探险。穿越平原、山脉和森林，历时近两年，他们最终抵达了这个地方，目之所及是滚滚江水西去的壮阔景象，浩浩荡荡的哥伦比亚河注入太平洋，无边无际的海水一直延伸至地平线。1811年，美国毛皮公司在附近建立了阿斯托里亚堡，这是美国在西海岸的第一个殖民地。155年后，图中的阿斯托里亚-梅格勒大桥竣工通车。这是一座横跨哥伦比亚河的连续桁架桥，101号美国国道从大桥上经过，连接洛杉矶和华盛顿奥林匹亚。来自美国7个州和加拿大2个省的水流经哥伦比亚河，穿过这座全长约21474英尺，北美最长的连续桁架桥。

Astoria-Megler Bridge, Oregon

Imagine traveling for nearly two years across plains, mountains, and forests and finally arriving at this setting, where the mighty Columbia River empties into the Pacific near present-day Astoria, Oregon. That is the sight that greeted explorers Meriwether Lewis and William Clark in 1805 at the culmination of their legendary 8,000-mile North American expedition that originated near St. Louis.

The expedition's success opened the way for further exploration and development of the Pacific Northwest and by 1811, Fort Astoria, the first US-owned settlement on the West Coast, was established. Oregon became the 33rd state in 1859. The Astoria-Megler Bridge opened in 1966, the final piece connecting Los Angeles to Olympia, Washington, via US Route 101.

Water from seven states and two Canadian provinces flows through the Columbia, passing under the 4-mile structure, the longest continuous truss bridge in North America.

一把通向岛屿的钥匙 A key to island travel

七英里大桥，佛罗里达州，美国

很久很久以前，佛罗里达州住着一位富有的实业家，名叫亨利·弗拉格勒。他启动了一项艰巨的工程：修建一条连接佛罗里达大陆和基韦斯特的跨海铁路。最终，七英里桥于1912年正式落成，被称为世界第八大奇迹。然而，奇迹并不长久，1935年，这座大桥遭遇飓风从而停止了运营。后来，这座桥被卖给了美国政府，经历重建后摇身一变，成了一条汽车高速公路，于1938年重新开放。

如今，你若到访这座久负盛名的七英里桥，你会发现两座桥：一座是老七英里桥，仅对行人和骑自行车的人开放，另一座是于1982年建成的新七英里桥，用于车辆通行。好莱坞大片《杀人执照》和《真实的谎言》中都曾出现过这座桥的身影。

Overseas Highway, Florida Keys

Once upon a time, there lived a wealthy industrialist, Henry Flagler, who embarked on the herculean task of creating an overseas railway connecting mainland Florida to Key West. When it opened in 1912, it was dubbed the Eighth Wonder of the World. However, the triumph was short-lived. It was hit by a hurricane on Labor Day, 1935 and the railroad discontinued operations. The railway was sold to the US government and rebuilt as an automobile highway, opening in 1938.

These days, the Overseas Highway still stretches about 113 miles through the Florida Keys over 42 bridges, which jump from island to island over the Atlantic Ocean, Florida Bay, and the Gulf of Mexico. Many of the original bridges were replaced in 1982, including the longest, the Seven Mile Bridge pictured in the distance in our homepage image. Drivers crossing the Overseas Highway can still see remnants of some of the old bridges running alongside their replacements, including the Old Seven Mile Bridge, a section of which was renovated for cyclists and pedestrians. An engineering marvel, the ‘highway that goes to sea' has also featured in blockbusters like 'License to Kill' and 'True Lies.'

将散落的岛屿连接在一起 Connecting the dots

斯托尔桑德特大桥，挪威

挪威的大西洋海滨公路连接了一系列大大小小的岛屿，一路上风景如画，设置有8座桥梁，其中最长的桥梁就是图上的这座斯托尔桑德特大桥。这座被自然美景环绕的桥梁，也是一个建筑奇迹。当地天气变幻莫测，这座桥在建设过程中就历经了12次飓风，最终奇迹般地建成了。斯托尔桑德特大桥有一个突兀的陡坡和急转弯，会给人造成一种大桥突然消失在海洋中的错觉，令司机们瞠目结舌，心如擂鼓。挪威斯托尔桑德特大桥与周围的天然美景融合得天衣无缝，很好地展示了挪威建筑工程的辉煌成就。

Storseisundet Bridge, Norway

Norway's picturesque Atlantic Ocean Road crosses eight bridges as it makes its way across islands, islets, and reefs to link the island of Averøya with the Romsdal Peninsula on the mainland. The longest of them, pictured here, is the Storseisundet Bridge. This bridge, surrounded by ample natural beauty, was tough to build. It took six years, and during construction workers were pelted by the region's unpredictable weather, including 12 hurricanes. It opened in 1989 and remains a popular visitor attraction. With its dramatic curve and sudden incline, Storseisundet Bridge creates the illusion of suddenly disappearing into the ocean, making drivers skip a heartbeat. Its construction showcases the brilliance of Norwegian engineering, blending seamlessly with the landscape.

一年已过半 We're halfway there

一年已过半

平年有365天，今天恰好是中间日，也就是平年的中间点。中间日，在平年的7月2日的中午开始，在闰年的7月2日的午夜开始。2023年是平年，所以你去吃午饭的时候正好是一年的中间点哦。

图上是荷兰的费吕沃湖水道桥。这座水道桥于2002年完工，采用了一种与众不同的设计：它没有让车辆直接横穿费吕沃湖，而是修建了一条水下隧道供汽车从水下通行，这样船只也可以自由地在水面通行了。这条隧道的两边都有人行横道，连接着大陆和世界上最大的人工岛弗莱福兰岛。工程师们本可以建造出一个只满足部分行人需求的东西，但是他们却找到了一个适用于所有人的解决方案。

It's Halfway Day!

Today is Halfway Day, which means we are halfway through 2023! Halfway Day begins at noon on July 2 during a regular 365-day year, and at midnight on July 2 during a leap year—so this year, we're celebrating at lunchtime.

Dutch engineers don’t do things by halves. Pictured here is the Veluwemeer Aqueduct in the Netherlands. The project, completed in 2002, used an unusual engineering approach. Rather than a drawbridge or ferry to get cars over Lake Veluwemeer, engineers instead built this 'water bridge' to carry boats across the road. The N302 is a busy highway connecting the mainland to the province of Flevoland, and thanks to this design, both road and waterborne traffic can keep flowing freely. The aqueduct also has pedestrian crossings on both sides, so everyone benefits. No half measures were taken in designing an eye-catching transport solution that works for everyone.

一座承载历史的桥 A bridge that holds up history

塞纳河上的桥，巴黎，法国

塞纳河流经法国巴黎，对这座古城的历史有着非比寻常的意义。公元前3世纪，一个名为帕里西人的凯尔特部落决定定居在塞纳河两岸之间的一座岛屿，即如今的西岱岛。在接下来的数个世纪里，塞纳河在巴黎发展成为全球商业和文化中心的过程中发挥了重要作用。

塞纳河穿过巴黎的河道十分辽阔，许多桥梁都横跨其间。巴黎共有37座普通桥梁和步行桥连接着城市的左右两岸。图中的映衬着落日的阿尔科勒桥在巴黎人心中占据着历史性地位，因为它在1944年为勒克莱尔将军解放巴黎的坦克提供了通道。

Pont d'Arcole over the Seine river, Paris, France

Welcome to Paris, France’s ancient capital city, through which flows one of the country’s longest rivers, the Seine. Human habitation here dates back to at least the 3rd century BCE, when a Gallic tribe called the Parisii settled on an island in the middle of the river. Today, that island is known as the Île de la Cité, seen on the left of our photo, and is home to Notre-Dame cathedral, as well as other striking buildings such as the medieval Conciergerie, pictured here.

It is linked to the Place de l'Hôtel-de-Ville by the Pont d’Arcole, one of 37 bridges connecting the city’s left and right banks. The Pont d’Arcole was built in the 1850s and holds a special place in Parisiennes’ hearts. In 1944, it supported General Jacques-Philippe Leclerc's tanks on their way to liberate Paris.

通往太平洋之窗 A window to the Pacific

天然桥州立公园，加利福尼亚州，美国

天然桥州立公园位于美国加利福尼亚州的圣克鲁斯市。初期，这里有三座海水侵蚀而成的拱桥，其中一座于1905年倒塌，后来又有一座于1980年倒塌，剩下我们如今看到的这座拱桥。然而，海浪的侵蚀是无情的，因此仅剩的这座拱桥最终也会倒塌。除了拱桥，这个公园还有君主斑蝶，因此也吸引了不少游客。

Natural Bridges State Beach in Santa Cruz, California

California brown pelicans, cormorants, and gulls enjoy jostling for position on top of this stunning rock formation in Natural Bridges State Beach in Santa Cruz. It is the sole surviving natural 'bridge' in this state park. Once three bridges stood side-by-side here, carved by waves into cliffs that jutted out into the Pacific. This one stood in the middle, but the outermost bridge collapsed in 1905 and the innermost one disappeared in 1980.

The erosion of the waves is relentless, so eventually the final arch will collapse, and the birds will have to find another favorite perch. But there are plenty of other views on offer. The park is also a seasonal home to migratory monarch butterflies, which flutter through the air or cluster together in its eucalyptus grove. And if you're lucky, you might spot a migrating whale or see seals and otters playing offshore.

工程学杰作 A masterpiece of engineering

魁北克大桥，加拿大

魁北克大桥是一座跨越圣劳伦斯河下游的公路、铁路、行人三用桥，连接加拿大魁北克省的桑特富瓦和莱维斯。魁北克大桥是一个工程学杰作，两座桥墩之间有549米长的主跨。魁北克大桥是世界上最长的悬臂桥，比苏格兰的福斯桥还长了27米。

1907年8月29日，这座桥在建设过程中垮塌了。事故之后，政府接手了建设工程。1913年，大桥的建设重启。新的设计增加了大桥主要应力结构的横截面面积，几乎是之前的2倍。但是悲剧重演了。在经历了两次悲剧后，魁北克大桥最终在1917年完工通车。

Asian American and Pacific Islander Heritage Month

This stunning structure is the stone pavilion housing the massive Korean Bell of Friendship in Los Angeles, a city with a large Korean American population. It's ringing in Asian American and Pacific Islander (AAPI) Heritage Month, which starts today. The month was chosen in recognition of the first documented arrival of Japanese immigrants, on May 7, 1843, and the completion of the transcontinental railroad by more than 20,000 Asian immigrants on May 10, 1869.

Back to that intricately decorated bronze bell. It was a gift to the city from South Korea to mark the US bicentennial in 1976 and is modeled on the largest bell cast in Korean history, the Divine Bell of King Seongdeok, made in 771. Both versions are among the largest bells in the world.

这座古桥在哪呢？ Where is this historical bridge?

古罗马桥，科尔多瓦，西班牙

科尔多瓦的古罗马桥跨越瓜达尔基维尔河，是这座城市的一处历史地标。这座桥始建于公元前1世纪罗马帝国的扩张时期，在历史上曾被多次重建，目前这座桥的主体是在8世纪由阿拉伯人重建。虽然它已经承载了数个世纪的交通往来，但现在这座桥仅供行人通行。如果你觉得它很眼熟，可能是因为你曾在《权力的游戏》第五季中见过它，在剧中它是虚构的瓦兰提斯城的一部分。

Roman bridge of Córdoba, Spain

The Roman bridge of Córdoba, in the ancient Spanish city’s historic center, has been rebuilt several times over the centuries. For 2,000 years it was the city’s only bridge across the Guadalquivir River, originally built in the first century BCE during the expansion of the Roman Empire. Much of the current bridge dates from reconstruction in the 8th century following the Moorish conquest, a period when hundreds of mosques and palaces were built, and Córdoba became one of Europe's largest cities and a center of learning and culture.

While it has seen centuries of traffic, the bridge is now only open to pedestrians, following the opening of the Miraflores Bridge in 2004. If it looks familiar, you might have spotted it standing in as part of the fictional city of Volantis in 'Game of Thrones.'

大自然的蓝色奇观 Nature's blue wonder

斯太尔河，奥地利

今天这张照片并未经过调色，奥地利斯太尔河的水真的就是这般湛蓝。斯太尔河流经托特斯山脉，当地植被稀少，那为什么斯太尔河还能如此清澈湛蓝？答案就在环绕斯太尔河谷的群山之中。雨水和融化的雪水流入斯太尔河后，其中较重的沉积物沉到水底，而较细的沉积物则会悬浮在水中。被沉积物散射或反射的阳光就赋予了河水这样鲜艳的蓝色。

Steyr River, Austria

These whitewater rapids are found in Upper Austria, where the Steyr River crashes down from the barren Totes Gebirge (the Dead Mountains) through this verdant landscape. When it comes to the ancient town of Steyr, at the foot of the Alps, it will meet the Enns River, which flows into the Danube.

What gives the Steyr that stunning blue hue? The answer is found in the mountains themselves. When there's rainfall or the surrounding snow melts, eroded sediment flows into the river. Heavier sediment sinks to the bottom and finer sediment stays suspended in the water. Sunlight is scattered or reflected by the sediment, allowing us to see a vibrant shade of blue, as the Steyr crashes through this lush landscape.
