Featured image for Top 10 Longest Vehicle-Carrying Sea Bridges

The bridges ranked here use official lengths of vehicle-carrying sea bridges, and tunnel sections or wider projects are labelled rather than mixed in. Rank is by the official length of a named vehicle-carrying sea bridge, meaning the bridge structure over water, and tunnel sections or wider connection projects are labelled rather than mixed into a silent different product ^[1]^[2]^[3]. The Hong Kong-Zhuhai-Macao Bridge is first, at the official Guinness World Records aggregate length over water of 48.3 kilometres ^[1]. Guinness also records that the entire crossing is 55 kilometres, including a 6.7-kilometre undersea tunnel; that total crossing figure is labelled and is not used as the ranking unit, because the tunnel is not a bridge ^[1]. Hangzhou Bay Bridge is second, at the official 36-kilometre length, and is the Guinness World Records longest bridge spanning open sea ^[2]^[3]. Donghai Bridge is third, at the official 32.5-kilometre length ^[4]. The Qingdao Jiaozhou Bay Bridge is fourth, at the official 26.707-kilometre bridge length; a wider Jiaozhou Bay Connection Project of about 41.58 to 42.23 kilometres is a different official product and is not used as a silent overtake of Donghai or Hangzhou Bay ^[5].

Later names remain in the same official sea-bridge class. The King Fahd Causeway is fifth, at the standard official length of 25 kilometres ^[4]. Incheon Bridge is sixth, at the standard official length of 21.38 kilometres ^[4]. The Shenzhen-Zhongshan Link has an official total of 24 kilometres, including an above-sea bridge section of about 17.2 kilometres; this article records the 17.2-kilometre bridge length as seventh, and labels the 24-kilometre total crossing so that it is not used to overtake Incheon Bridge or the King Fahd Causeway ^[6]. Confederation Bridge is eighth, at the official 12.9-kilometre length ^[4]. The Ã˜resund crossing is a bridge-and-tunnel system, and only its official bridge section belongs in this class; it sits outside this ten on that bridge-only figure, and its longer total crossing is labelled and is not used as a silent later cell ^[4]. Railway viaducts over land or canals, including the Danyang-Kunshan Grand Bridge, and lake crossings, including the Lake Pontchartrain Causeway, are different products and are not mixed into this vehicle-carrying sea-bridge ten. This article does not copy official crests, flags, or exact pylon likenesses as decorative art.

Key Facts

The ten below are the labelled official sea-bridge leaders, ranked strictly by the stated official bridge-over-water length: the Hong Kong-Zhuhai-Macao Bridge, 48.3 kilometres; Hangzhou Bay Bridge, 36 kilometres; Donghai Bridge, 32.5 kilometres; the Qingdao Jiaozhou Bay Bridge, 26.707 kilometres; the King Fahd Causeway, 25 kilometres; Incheon Bridge, 21.38 kilometres; the Shenzhen-Zhongshan above-sea bridge, about 17.2 kilometres; Pingtan Strait Bridge, 16.34 kilometres; Penang Bridge, 13.5 kilometres; and Confederation Bridge, 12.9 kilometres ^[1]^[2]^[4]^[5]^[6]. Rank 1 is the outstanding official aggregate length over water, which stands well above every later named sea bridge.

The table is the official spine: official bridge-over-water length first, tunnels and wider projects labelled, and no silent substitution of a total crossing figure.

1. Hong Kong-Zhuhai-Macao Bridge

The Hong Kong-Zhuhai-Macao Bridge is first, at the official Guinness World Records aggregate length over water of 48.3 kilometres ^[1]. Guinness records that the entire crossing is 55 kilometres, including a 6.7-kilometre undersea tunnel, and that the crossing opened on 23 October 2018 ^[1]. The 55-kilometre total is a different official product, because it includes a tunnel, and it is not used here as the ranking unit ^[1]. This article records the official 48.3-kilometre aggregate over-water figure. It stands well above Hangzhou Bay Bridge at 36 kilometres.

It is first as the outstanding official aggregate length over water, a labelled fact, and the documentary centre of this ten ^[1]. A later official revision will belong in a revision of the cell.

The Guinness World Records title for the longest bridge over water, aggregate length, is the source ^[1].

2. Hangzhou Bay Bridge

Hangzhou Bay Bridge is second, at the official 36-kilometre length ^[2]^[3]. Guinness World Records recognises it as the longest bridge spanning open sea ^[2]. The figure is an official sea-bridge length, not a total crossing that includes a tunnel, and not a later unofficial estimate. This article records the official 36-kilometre figure. It stands above Donghai Bridge at 32.5 kilometres.

It is second as the outstanding official 36-kilometre sea-bridge length, a labelled fact, and a necessary counterpart to Donghai Bridge ^[2]^[3]. A later official revision will belong in a revision of the cell.

Official project statements and the Guinness World Records open-sea title are the sources ^[2]^[3].

3. Donghai Bridge

Donghai Bridge is third, at the official 32.5-kilometre length ^[4]. The figure is an official sea-bridge length, not a later unofficial estimate, and not a silent combination with any later Shanghai crossing that is not a sea bridge.

Conclusion

A 2026 longest vehicle-carrying sea-bridges list has to keep the Hong Kong-Zhuhai-Macao Bridge at the official 48.3-kilometre aggregate over water, keep the 55-kilometre tunnel-inclusive crossing in the open, and refuse to treat a wider connection project or a railway viaduct as a silent official sea-bridge cell ^[1]^[5]. Hangzhou Bay Bridge, Donghai Bridge, the Qingdao Jiaozhou Bay Bridge, the King Fahd Causeway, Incheon Bridge, the Shenzhen-Zhongshan above-sea bridge, Pingtan Strait Bridge, Penang Bridge, and Confederation Bridge complete a named ten in which official bridge lengths and tunnel or project totals are stated in the open ^[2]^[4]^[6]. The useful habit is an official bridge-over-water length, a labelled tunnel or project total, and a refusal to mix a total crossing into a current official bridge cell.

A later official revision will belong in a revision of a cell; it will not change the method. Those labelled official lengths are the spine of the list, and they will still be the spine after a later official survey has restated a sea-bridge length.
