Pont du Gard Aqueduct
One of the oldest remaining aqueducts built by the Roman Empire, the Pont du Gard is believed to have been constructed between 19 BCE and 150 CE. The stones that make up the aqueduct were carved with precise measurement, meaning that there was no mortar needed to hold the structure together. It is not hard to see why it took nearly two centuries to complete. The bridge is composed of three tiers of arches, stands up to 48.8 meters high, and is 275 meters long.
Royal Gorge Bridge
Canon City, Colorado
The world’s highest suspension bridge, the Royal Gorge hangs 955 feet above the base of the Arkansas River. While it bears a striking resemblance to a setting near the end of Indiana Jones and the Temple of Doom, the real attraction is parachuters who like to freefall from the bridge to the valley below. The bridge features two 150-feet-high towers and spans 1,260 feet in length. From 1929 until 2001, it was once considered the highest bridge in the world.
As it twists its way through the Alps, this extradosed bridge had caught the attention of people all over the world since its completion in 1998. The Sunniberg Bridge won the Outstanding Structure Award in 2001 for its "aesthetically pleasing appearance and innovative design." The bridge spans 526 meters and up to 60 meters above the valley below.
The Khaju Bridge is as functional as it is beautiful. Not only is it a passageway for travelers, it also regulates the flow of the Zayandeh River. Built in 1650, on the foundations of an even older bridge, this is a great location for history buffs or anyone else who enjoys romantic walks. The bridge is made up of 23 arches and is 133 meters long.
Brave Men's Bridge
Hunan Province, China
Recently opened in China's Shiniuzhai National Geological Park, Brave Men's Bridge is the longest and tallest glass-bottom bridge in the world. Visitors who dare to step out on to the transparent platform will have an unobstructed view 590 feet above the canyon floor. Just two weeks after opening, however, cracks began to appear in the glass. The bridge extends nearly 300 meters in length!
Golden Gate Bridge
San Francisco, California
Probably the most iconic bridge in the United States, the Golden Gate Bridge was the longest suspension bridge in the world until 1964. The total length of the bridge is 2,737.1 meters. The red paint draws the attention of the human eye, and it blends beautifully into the San Francisco skyline. With its beauty also comes the gruesome distinction of being the most used site for suicides. To help stem these suicide attempts, a net covered is scheduled for completion by the year 2023.
No one knows art quite like the Italians. This Medieval bridge over the Arno River comprises many unique shops and art dealers. It is the oldest stone, closed-spandrel segmental arch bridge in Europe. Originally built as far back as the 12th century, it was rebuilt a few times with the final time in 1345. It measures about 90 meters in length. The Ponte Vecchio is so beautiful that Adolf Hitler ordered it to be preserved as the Nazis destroyed many surrounding structures.
Akashi Kaikyo Bridge
Also known as the “Pearl Bridge,” this 1.2-mile long architectural wonder has earned the title of World’s Longest Suspension Bridge. Before its completion, the Pearl Bridge held up against the force of the Kobe Earthquake in 1995, showing its flawless and durable design.
As recognizable as the River Thames itself, Tower Bridge is one of London’s most photographed landmarks. Finished in 1894, this European treasure is something out of a fairy tale.

Tarn Valley, France
The construction of the Millau Viaduct set two world records in 2004: the highest pylons in the world as well as the highest bridge tower. It also has the highest road bridge deck in Europe, which makes crossing this landmark rather daunting. The total length of the roadway is 2,460 meters, while the tallest pylon is 336.4 meters. Another oddity is that this bridge stretches over land rather than water.
Eastern Docklands, Amsterdam
The Python Bridge, also known as High Bridge, slythers across the canal between Sporenburg and Borneo Island in Amsterdam. Someone was partying a little too much in Amsterdam when they designed this bridge because it's not too practical. The bridge features stairs and you have to actually push your bike up a ramp if you need to get it across this bridge. The bridge spans 90 meters and was completed in 2001.
The Rolling Bridge, completed in 2004, is the fruit roll-up of bridges - minus the fruit part. As part of the Grand Union Canal office and retail development project in London, this unique bridge curls and straightens like something out of a cartoon or harry potter movie. It consists of eight triangular sections that collapse via hydraulic cylinders that are mounted vertically between the sections. It's strange, to be sure, but really cool.
Henderson Rd, Singapore
The Henderson Waves bridge is part of a system of trails connecting three parks along the southern ridge of Singapore. The Henderson Waves bridge connects Mount Faber Park and Telok Blangah Hill Park and is 274 meters long and 36 meters high, making it the tallest pedestrian bridge in Singapore.

The support tower of the bridge is a giant sundial and it 217 feet. Completed in 2004, the bridge is estimated to have the cost of $23.5 million, and has since become an iconic landmark in Redding – but really, that's obvious. How the heck could you miss it?
The Pont Gustave-Flaubert bridge is part elevator, part bridge. The vertical-lift bridge reaches across the River Seine in Normandy, France. It took four years to build and was finished in 2008. The bridge features two high-rise towers that help the bridge raise and lower to allow for the passage of vessels.
The Millennium Bridge in London is a steel suspension bridge that reaches across the River Thames. The bridge is owned and maintained by Bridge House Estates.

The unique design of the bridge has made it iconic in London, and it's probably the most modern-looking thing in the city, making it really stand out.
The Chengyang Bridge, also known as the Wind and Rain Bridge, is not just a bridge. Its also made up of verandas, corridors, and pavilions. The piers of the bridge were made entirely of stone and the upper structures – wood. Tiles cover the rooves of the pavilions. Constructed in 1912, the bridge is both beautiful and fascinating.
How this bridge still stands – we do not know. The Pira Delal bridge in Iraq is an ancient bridge that crosses the Khabur river. It's so old, in fact, that nobody is exactly sure how old it is or even where it came from. The stone bridge is believed by some to have been built in the time of ancient Rome. The bridge is 115 meters long.
This bridge doesn't look like much but what is so impressive is how well it has stood the test of time. Built during the Song dynasty (in 1151), the bridge is made of granite beams laid over what was the Shijing River. Stone piers have held the thing up for almost a thousand years. It is a protected historic site thanks to the National Cultural Heritage Administration.
The Helix Bridge
The Helix Bridge, also in Singapore, is a 280-meter-long bridge. Made of specialized stainless steel, the Helix Bridge was built with remarkable care and precision over the course of two years. Completed in 2010, the helix-shaped canopies provide the pedestrian bridge with shade as they make the long trek over the Marina Bay.
