Longest Bridges in the World
Have you ever wondered which bridge is the longest in the world? Or what are the top 10 longest bridges in the world? If so, this blog post is for you!
There are many factors that go into determining how long a bridge is and where it ranks on this list. Some include length, the height of the deck above water level, the width of the road surface. These bridges vary in design from suspension to arch to cantilever as well.
When you live in a world where the tallest buildings are only as high as an average apartment building, it is easy to forget we still have bridges that can span miles of water. Spanning distances from 5-over-5 kilometers long to more than 12-over-12 kilometers long, these bridges offer some spectacular views and scenic routes for drivers.
The longest pedestrian bridge in the world is the Brooklyn Bridge which spans 1,595 meters over water and connects Manhattan Island with Brooklyn, New York City. The second-longest pedestrian bridge is Yavuz Sultan Selim Bridge in Istanbul which has a length of 1,510 meters.
The longest bridges in the world are not just about their length, but also about the engineering marvels they represent. From cable-stayed bridges to arch bridges and suspension bridges, there is always a story behind these long spans of steel or concrete that connect two points across water, land, or both.
The longest bridges in the world are located all over our planet, and some of them span rivers or other natural obstacles. These 10 bridges have been identified as the longest in the world by a number of sources, with lengths ranging from 15 to 9 miles long! Let’s take a look at these amazing feats of engineering and see what they’re like.

10) Line 1, Wuhan Metro Bridge
- Location: Wuhan, China
- Length: 37,788 meters
- Length: 16.56 miles (26.82 kilometers)
- Construction time: July 15th, 2004 – December 30th, 2010
- Status: In use for public transit service as of January 2011
The Line One bridge in the city of Wuhan is part of a $250 million, two-year project to build a metro system in the city. The bridge is located near Wuhan University and crosses the Yangtze River before reaching its north bank.
Construction of Line One began on July 15th 2003 with support from China’s Ministry of Railways. A groundbreaking ceremony was held at the site for what would become the longest subway in China and one of the longest bridges as well. This is one of the Longest Bridges in the World 2021.
A total of five days were required for the engineering team to put a temporary span across the Yangtze River so that construction could continue uninterrupted on each side, with work starting at opposite ends until they met.
The bridge’s completion was delayed by nearly three years after it was damaged in the 2008 Sichuan earthquake.
The bridge was completed and opened to traffic on January 15th 2011, with a length of 17 km (11 miles).
This is the first metro line in China that was incorrectly referred to as a light rail because it’s elevated. Originally, they wanted this branch line on their map cross-wise over Yangtze River till Wuchang District through Second Wuhan Bridge across where you can find bridges connecting Hubei and Hunan Province together.
9) Lake Pontchartrain Causeway, USA
- Length: 38,442 meters
- Country: United States
- Completed in: 1956 (southbound), 1969 (northbound)
The longest bridge in North America is the Lake Pontchartrain Causeway, a 24.93 kilometer (14 mile) long series of bridges and causeways that connects Metairie to Mandeville, Louisiana across the lake’s northern end. Begun as early as 1929, but not completed until 1956 due to World War II , the Causeway was considered an engineering marvel because it featured a twin-span continuous steel girder bridge without supports for vehicles. This is one of the Top 10 Longest Bridges in the World 2021.
In 2010, the Louisiana Department of Transportation and Development made another engineering marvel by constructing a five-mile span bridge with no piers in water to connect Slidell to Mandeville. The new twin-span continuous steel girder bridges without supports for vehicles will allow motorists an easier transition from I-12 on the west bank of the Mississippi River to US 190 on the east bank.
The longest bridge over water in the world was listed by Guinness World Records from 1969 until 2011 when it created two categories for bridges. Nowadays Lake Pontchartrain Causeway is titled as the longest continuous one while Jiaozhou Bay Bridge became of the aggregate length titleholder.
8) Beijing Grand Bridge, China
- Length: 48,153 meters
- Country: China
- Completed in: 2010
The Beijing Grand Bridge is a suspension bridge and the first of its kind in China, spanning the Yongding River about 12 kilometers (seven miles) to connect central Beijing with Jinshanling. Opened on Oct 28th, 1986 after six years of construction at a cost of ¥230 million dollars, it was designed by He Zhen-Zhong and Chang San-Xin.
The bridge has a total length of 14,880 meters (16,000 yards), with the longest span being 680 meters; it carries traffic on six lanes for automobiles and two railway tracks in each direction. The Beijing Grand Bridge was designed to withstand an earthquake magnitude as high as eight (Mw) according to the Richter scale. This is one of the Longest Bridges in the World 2021.
It is the longest suspension bridge in China and one of the world’s ten longest bridges, with a total length of 14,880 meters. The Beijing Grand Bridge has been named as an important cultural relic by State Administration for Cultural Heritage in 2011.
The design was said to have been copied from Tsing Ma Bridge (in Hong Kong) and it was the first bridge designed by a Chinese architect to cross Beijing’s River.
The construction of this project started on September 21, 1987, with an investment of 450 million yuan (US$83.07 million). The construction work took ten years to completion with more than two thousand workers involved in the labor force at that time.
7) Sheikh Jaber Al-Ahmad Al-Sabah Causeway, Kuwait
- Length: 48,500 meters
- Country: Kuwait
- Completed in: 2019
Sheikh Jaber Al-Ahmad Al-Sabah Causeway is the longest bridge in Kuwait. The construction of this project began on September 12, 2009 and took five years to complete at a cost of $US65 million.
This causeway is one of the most important infrastructure projects for the country as it will provide much-needed access across Mina Al-Shuwaikh Bay from Shuwaikh Port District to Kuwait City, and will also connect with the planned new Sheikh Jaber Al-Ahmad Al-Sabah Bridge.
The causeway is expected to take pressure off of other links across Mina Al-Shuwaikh Bay such as the Mubarak Causeway which has been affected by high traffic volumes in recent years. This is one of the Longest Bridges in the World 2021.
The Sheikh Jaber Al-Sabah bridges are a set of two long, perfectly arched steel structures. They were named after the late sheikh who was in power during Kuwait’s Gulf War to commemorate his role and contributions to developing those around him. The Main Link is one of the longest roadways out there at 36 kilometers while both have combined lengths totaling up 48 miles.
6) Bang Na Expressway
- Length: 54,000 meters
- Country: Thailand
- Completed in: 2000
The Bang Na Expressway is the longest roadway in Thailand. It runs from Huay Khwang district to Chon Buri, and was completed on December 29th, 1985 at a cost of THB477 million (approximately US$14.45 million). The highway has two lanes in each direction and it crosses over 50 bridges with 24 interchanges. This is one of the Longest Bridges in the World 2021.
The Bang Na Expressway is the first toll road in Thailand and was designed by Louis Berger, an American consulting firm. The 55 km long six-lane elevated highway runs above National Highway Route 34 (Bangna – Trat) which is owned by EXAT. It’s a modern marvel with it being so high up that cars can barely be seen on any of its lanes due to height restrictions along portions of the expressway as well as many safety features such as lane separators and pedestrian crossings for those who are unfortunate enough to find themselves down there below during rush hours or severe weather conditions.
5) Weinan Weihe Grand Bridge, China
- Length: 79,732 meters
- Country: China
- Completed in: 2008
The Weinan Weihe Grand Bridge is the longest bridge in northern Shaanxi and it’s a suspension bridge with an impressive length of 4925 m. The deck carries two lanes for traffic as well as sidewalks, bike paths, noise barriers, and other safety equipment to keep those who use the sidewalk safe from oncoming vehicles. It was completed in 2006 and so far has had no major incidents or disasters of note.
the Weihe Grand Bridge is a 2.9-kilometer-long bridge that connects two sides of an artificial lake and spans over water on both its ends as well. The project was completed with 10,000 workers who helped build it out o f2,300 cubic meters of concrete and 45 tons worth of steel to help make sure this magnificent structure would be able to withstand anything! You can see how strong these materials are just by looking at the photo because they’re so thick – which made them perfect for protecting against natural disasters like earthquakes or tsunamis since those types of events happen more often than not here in Asia.
The design process began back in 1999 when five teams from Beijing submitted designs
4. Cangde Grand Bridge
- Length: 105,810 meters
- Country: China
- Completed in: 2010
The longest bridge in the world is a steel and concrete hybrid that’s about 13.35 miles long! It connects an area of China to its other halves, which were split up by a river. The Cangde Grand Bridge was so complex it took four years just to design it and another nine for construction – there was simply no way to build it quickly. This is one of the Longest Bridges in the World 2021.
The Weinan Weihe Grand Bridge is part of the Zhengzhou-Xi’an High-Speed Railway which connects Zhengzhou and Xi’an. The bridge spans two hundred twenty-nine thousand, seven hundred thirty-one meters (261,588 ft) long across a lot of rivers including the Wei River twice as well as many other highways or railways on its way to connecting both cities in China. It was once considered by Guinness World Records to be “the longest bridge in the world” when it originally opened back in 2010 but this title has since been surpassed by Beijing’s newest bridges that were completed just last year with their lengths stretching out at around 300 meters each!
