11 Longest Bridges In Asia

China holds eight of the eleven longest bridges in Asia. Four of those carry one rail line, the Beijing-Shanghai High-Speed Railway. The Danyang-Kunshan Grand Bridge alone runs 102.4 miles across the Yangtze Delta and is the longest bridge in the world by any measure. Taiwan's Changhua-Kaohsiung Viaduct is the second-longest at 97.7 miles. Japan's Kita-Yaita Viaduct on the Tohoku Shinkansen is the oldest entry on the list at over four decades in service. The list below reflects what Asia has built between 2000 and the present.

1. Danyang-Kunshan Grand Bridge, China - 102.4 miles

The Danyang-Kunshan Grand Bridge is the longest bridge in the world at 102.4 miles (164.8 km). The viaduct opened in June 2011 as part of the Jinghu High-Speed Railway (the Beijing-Shanghai High-Speed Railway) and crosses the canals, lakes, and rice-paddy floor of the Yangtze River Delta on its run between Shanghai and Nanjing. The structure mostly sits 10 to 30 meters above ground for the standard viaduct stretches, with sections rising over 100 feet of clearance where the line crosses the Yangtze itself to give ship traffic room underneath. The Beijing-Shanghai line was Chinese high-speed rail's flagship project and the Danyang-Kunshan was the marquee engineering feat that made the timeline work.

2. Changhua-Kaohsiung Viaduct, Taiwan - 97.7 miles

Western Taiwan's Changhua-Kaohsiung Viaduct is the second-longest bridge in the world at 97.7 miles (157.3 km). The structure is actually a series of linked bridges that together carry Taiwan's High-Speed Rail from Baguashan in Changhua County south to Zuoying in Kaohsiung City. The whole line sits squarely on the boundary between the Philippine Sea Plate and the Eurasian Plate, so the viaduct was engineered from the start to absorb significant earthquakes. The bridge has been in operation since the THSR line opened in 2007 and has come through multiple major quakes intact.

3. Kita-Yaita Viaduct, Japan - 71.1 miles

Japan's 71.1-mile (114.4 km) Kita-Yaita Viaduct is a section of the Tohoku Shinkansen high-speed line connecting Tokyo (specifically the Kita Ward area of the capital) north to the city of Yaita in Tochigi Prefecture. The Tohoku Shinkansen is the longest Shinkansen line in the country, running between Tokyo and Aomori at the northern tip of Honshu, the largest and most populous of Japan's main islands. The Kita-Yaita section opened in 1982, which makes it the oldest bridge on this list by almost two decades.

4. Tianjin Grand Bridge, China - 70.6 miles

The Tianjin Grand Bridge is another Beijing-Shanghai High-Speed Railway segment, 70.6 miles (113.7 km) of viaduct between the Langfang prefecture and Qingxian (Qing County) in Hebei Province. The bridge opened in June 2011 alongside the Danyang-Kunshan. The construction relied on prefabricated reinforced box-girder segments, each weighing hundreds of tons, lifted into place by purpose-built launching gantries that worked their way along the alignment in sequence.

5. Cangde Grand Bridge, China - 65.8 miles

The Cangde Grand Bridge is the third Beijing-Shanghai segment in the top five. The bridge runs 65.8 miles (105.9 km) and sits on more than 3,000 piers across coastal eastern Hebei, designed to absorb the regular seismic activity of the area. The fact that the same line accounts for three of the longest bridges in the world reflects how the engineers chose to handle the route's flat, soggy, intensely built-up terrain: rather than negotiating road crossings and floodplain settlements at grade, they put the whole alignment up on viaduct and ran it straight.

6. Weinan Weihe Grand Bridge, China - 49.5 miles

When the Weinan Weihe Grand Bridge opened in 2008, it held the Guinness World Record for the world's longest bridge. The 49.5-mile (79.7 km) viaduct carries the Zhengzhou-Xi'an High-Speed Railway through east-central China, connecting the Henan provincial capital Zhengzhou with the Shaanxi provincial capital Xi'an. The record didn't last long. Within three years, four longer Chinese bridges had been built and the Weinan Weihe had dropped to sixth on the world list, all without a single one being built outside Asia.

7. Bang Na Expressway, Thailand - 33.6 miles

Thailand's Bang Na - Bang Phli - Bang Pakong Expressway, generally just called the Bang Na Expressway (formally the Burapha Withi Expressway), holds the Guinness World Record for the longest road bridge. Unlike the high-speed rail viaducts in this list, the Bang Na is a six-lane elevated toll road. Its 33.6-mile (54 km) length runs between the Bang Na and Chon Buri Interchanges and was built to relieve the chronic ground-level congestion on National Highway Route 34 (the Bang Na-Trat Highway) for traffic moving in and out of Bangkok. The bridge opened on February 7, 2000.

8. Hong Kong-Zhuhai-Macau Bridge, China - 30 miles

The Hong Kong-Zhuhai-Macau Bridge holds another world record. It shares the title of longest bridge over water with Louisiana's Lake Pontchartrain Causeway, with the records distinguished by category: the Hong Kong-Zhuhai-Macau structure is recognized for "aggregate length" while the U.S. bridge holds the "continuous length" title. The Chinese structure runs 34 miles (55 km) end to end but transitions through a 4.3-mile (7 km) immersed tunnel midway, which is why the formal Guinness figure for the bridge alone is 30 miles (48.3 km). The structure connects Hong Kong, Zhuhai, and Macau across the Pearl River Delta and has measurably cut commute times between the three cities since opening in 2018.

8. Beijing Grand Bridge, China - 30 miles

The Beijing Grand Bridge is the fourth Beijing-Shanghai High-Speed Railway entry on this list. The bridge runs 29.9 miles (48.2 km) from Beijing South Station east through the inner suburbs to Langfang in Hebei Province, kicking off the southbound run from the capital. Beyond carrying high-speed passenger rail, the bridge corridor connects the Yangtze River Delta industrial heartland with the Bohai Economic Rim, making it a key freight conduit alongside its passenger role.

10. Metro Manila Skyway System, Philippines - 24.4 miles

The Metro Manila Skyway System is the only other elevated road bridge on this list besides the Bang Na. The 24.4-mile (39.2 km) tolled expressway in the Philippines connects the North and South Luzon Expressways across the metropolitan area, bypassing the surface-level congestion of central Manila and several adjacent cities. The Skyway has been built in stages: Stage 1 opened in 1999, Stage 2 in 2011, and Stage 3 (the most ambitious section, running north of the Pasig River) opened in stages from 2020 through 2024.

11. Wuhan Metro Bridge, China - 23.5 miles

The list closes with Wuhan, the capital of Hubei Province. Line 1 of the elevated Wuhan Metro covers 23.5 miles (38 km) between the Huangpu Lu and Zhongguan stations, with 32 stations in between, making it the longest elevated metro line in the world. The line opened in 2004 to relieve the road-bridge bottleneck across the Yangtze that had carried most of the city's east-west traffic up to that point. It was Wuhan's first metro line and is still the spine of what is now a much larger system.

Mapping the Asian Bridge Boom

The list of longest bridges in Asia overlaps almost completely with the world list, and Chinese projects dominate both. Most of these structures are post-2000 builds, and most carry high-speed rail rather than road traffic. The longer table below extends the ranking to the top 25 across the continent.
