10 of the Longest Bridges in the World
Read Time: 4m
Original photo by Art Wager/ iStock


Most of the world’s longest bridges have one thing in common: They’re in Asia,
usually China. The Middle Kingdom is responsible for six of the 10 longest
bridges in the world, with two in the United States (oddly, both in Louisiana)
and one apiece in Thailand and Taiwan. Most of these bridges were also built
recently, but several are just over a decade old. Here, for your reading and
traversing pleasure, are 10 of the longest bridges in the world.

MANCHAC SWAMP BRIDGE (U.S.)

Should you ever find yourself in the area near Ponchatoula, Louisiana, you may
be among the 2,250 drivers who use the Manchac Swamp Bridge on a daily basis. It
extends 22.8 miles over a swamp that’s said to be haunted by either a Voodoo
princess, a rougarou (Cajun werewolf), or both. Even if you don’t believe in
such things, there’s no dismissing the alligators in the water below as mythical
creatures.

WUHAN METRO BRIDGE (CHINA)

The Yangtze is the longest river in Asia, flowing 3,915 miles from Tibet’s
Tanggula Mountains to the East China Sea. Until 1957, no bridges crossed it and
travelers relied on ferries. Now there are many crossings, the longest of which
is the 23.48-mile Wuhan Metro Bridge. Part of the city’s elevated Metro line, it
opened in 2004.

LAKE PONTCHARTRAIN CAUSEWAY (U.S.)

Credit: Art Wager/ iStock

Better known as the Causeway, this feat of engineering in southeastern Louisiana
is recognized by Guinness World Records as the longest continuous bridge over
water. Spanning 23.87 miles and completed in 1969, it’s known to cause a feeling
of unease: Once you reach the middle, land isn’t visible in either direction and
water stretches as far as the eye can see.

BEIJING GRAND BRIDGE (CHINA)

Credit: Future Publishing via Getty Images

Part of the Beijing–Shanghai High-Speed Railway, as are several others on this
list, this railway viaduct connects Beijing South and Langfang (located roughly
midway between Beijing and Tianjin). The bridge measures 29.8 miles.
Construction began in 2010 and was completed the following year.


5of 10


BANG NA EXPRESSWAY (THAILAND)

Credit: Casper1774 Studio/ Shutterstock

Until 2008, the Bang Na Expressway — also known as the Burapha Withi Expressway
— was the longest bridge in the world, at 33.5 miles long. It held that record
for eight years, having been built in 2000, and cost $1 billion to construct.
It’s unusual on this list in that it doesn’t cover a body of water, but it does
carry a six-lane highway above another highway.


6of 10


WEINAN WEIHE GRAND BRIDGE (CHINA)

Connecting the cities of Zhengzhou and Xi’an on the Zhengzhou–Xi’an High-Speed
Railway, the Weinan Weihe Grand Bridge crosses the Wei, Luofu, Xi, Shi Di, and
Ling rivers. It was briefly the longest bridge in the world when it was
completed in 2008, but its 49.5 miles were quickly surpassed.


7of 10


TIANJIN GRAND BRIDGE (CHINA)

At 70.2 miles long, this railway viaduct spanning from Langfang and Qingxian is
also part of the Beijing–Shanghai High-Speed Railway. It was completed in 2010,
after four years of construction, and has been used continuously since 2011.


8of 10


CANGDE GRAND BRIDGE (CHINA)

Credit: Future Publishing via Getty Images

Can you guess which high-speed railway the Cangde Grand Bridge is part of? If
you guessed Beijing–Shanghai, you’re right on the money. Said railway runs 819
miles, hence the need for so many proportionally huge bridges. This one comes in
at 72 miles long and has 3,092 piers.


9of 10


CHANGHUA–KAOHSIUNG VIADUCT (TAIWAN)

Credit: AaronChenPS2/ Shutterstock

A viaduct completed in 2007, the Changhua–Kaohsiung Viaduct is part of the
Taiwan High Speed Rail network and is 97.8 miles long. It was built to withstand
earthquakes, as this part of Taiwan is known for its seismic activity.


10of 10


DANYANG-KUNSHAN GRAND BRIDGE (CHINA)

Credit: ullstein bild via Getty Images

At a whopping 102.4 miles long, the Danyang-Kunshan Grand Bridge is the longest
in the world — and probably will be for some time to come. (Do we even need to
mention that it’s part of the Beijing–Shanghai High-Speed Railway at this
point?) Carrying a price tag of $8.5 billion (or $83 million per mile), it was
built to withstand seismic activity, extreme weather, and impact with very large
boats (just in case). Constructed over a five-year period between 2006 and 2011,
it stands at an average height of 328 feet.
