Hong Kong–Zhuhai–Macau Bridge

Template:Use Hong Kong English Template:Use dmy dates Template:Infobox bridge Template:Chinese The Hong Kong–Zhuhai–Macau Bridge (HZMB) is a Template:Convert bridge–tunnel system consisting of a series of three cable-stayed bridges, an undersea tunnel, and four artificial islands. It is both the longest sea crossing<ref>Template:Cite news</ref><ref>Template:Cite news</ref> and the longest open-sea fixed link in the world.<ref name=":Chatwin">Template:Cite book</ref> The HZMB spans the Lingding and Jiuzhou channels, connecting Hong Kong and Macau with Zhuhai—a major city on the Pearl River Delta in China.

The HZM Bridge was designed to last for 120 years and cost ¥127 billion (US$18.8 billion) to build.<ref name=Xin201810/> The cost of constructing the Main Bridge was estimated at ¥51.1 billion (US$7.56 billion) funded by bank loans and shared among the governments of mainland China, Hong Kong and Macau.<ref>Template:Cite news</ref>

Originally set to be opened to traffic in late 2016,<ref name="asia.nikkei.com">Template:Cite web</ref><ref name="chinadaily7july2017" /><ref>Template:Cite web</ref> the structure was completed on 6 February 2018<ref name="complete" /> and journalists were subsequently taken for a ride over the bridge.<ref>Template:Cite news</ref><ref name=":0">Template:Cite web</ref> On 24 October 2018 the HZMB was opened to the public after its inauguration a day earlier by General Secretary of the Chinese Communist Party Xi Jinping.

Planning

Background

Hopewell Holdings founder and then-managing director Gordon Wu proposed the concept of a bridge-tunnel linking mainland China, British Hong Kong and Portuguese Macau in the 1980s.<ref>Template:Cite news</ref> Wu stated that he got the idea in 1983 from the Chesapeake Bay Bridge–Tunnel. In 1988 Wu pitched the concept to Guangdong and Beijing officials. He envisaged a link farther north than the current design, beginning at Black Point near Tuen Mun, Hong Kong and crossing the Pearl River estuary via Nei Lingding Island and Qi'ao Island. His proposed bridge would have ended at the Chinese village of Tangjia, and a new road would have continued south through Zhuhai before terminating at Macau.<ref name="bridgetochina">Template:Cite news</ref> Discussions stalled after the Tiananmen Square protests in mid-1989 "unnerved" Wu and other foreign investors, and caused Hopewell's Hong Kong share prices to plunge.<ref name="entrepreneurbecomes">Template:Cite news</ref>

The route proposed by Wu was promoted by the Zhuhai government under the name Lingdingyang Bridge. In the mid-1990s, Zhuhai built a bridge between the Zhuhai mainland and Qi'ao Island that was intended as the first phase of this route, though the full scheme had not been approved by either the Chinese or Hong Kong governments at the time.<ref name="firstlingdingyang">Template:Cite news</ref> China's central government showed support for this project on 30 December 1997.<ref name="beijingapproves97">Template:Cite news</ref> The new Hong Kong government was reluctant, stating that it was still awaiting cross-border traffic study results, and Hong Kong media questioned the environmental impact of the project with regard to air pollution, traffic and marine life.<ref name="toofar">Template:Cite news</ref>

In December 2001 the Legislative Council of Hong Kong passed a motion urging the Administration to develop the logistics industry including the construction of a bridge connecting Hong Kong, Zhuhai and Macao. In September 2002, the China/Hong Kong Conference on Co-ordination of Major Infrastructure Projects agreed to a joint study on a transport link between Hong Kong and Pearl River West.<ref>Template:Cite web</ref>

Preparation

To coordinate the project, the Advance Work Coordination Group of HZMB was set up in 2003. Officials from three sides solved issues such as landing points and alignments of the bridge, operation of the Border Crossing Facilities, and project financing.<ref>Template:Cite web</ref>

In August 2008, China's central government, the governments of Guangdong, Hong Kong and Macau agreed to finance 42 percent of the total costs. The remaining 58% consisted of loans (approximately ¥22 billion or US$3.23 billion) from the Bank of China.<ref>Template:Cite news</ref>

In March 2009, it was further reported that China's central government, Hong Kong and Macau agreed to finance 22 percent of the total costs. The remaining 78 percent consisted of loans (approximately ¥57.3 billion or US$8.4 billion) from a consortium of banks led by Bank of China.<ref>Template:Cite news</ref>

Construction

Construction of the HZMB project began on 15 December 2009 on the Chinese side,<ref>Arup: "Hong Kong-Zhuhai-Macao Bridge ground breaking" Template:Webarchive, 9 February 2010. Retrieved 22 December 2011.</ref> with the CCP Politburo Standing member and Vice Premier of China Li Keqiang holding a commencement ceremony. Construction of the Hong Kong section of the project began in December 2011 after a delay caused by a legal challenge regarding the environmental impact of the bridge.<ref>Macau Daily Times: "Pearl River Delta Bridge work begins" Template:Webarchive, 15 December 2011. Retrieved 22 December 2011.</ref>

The last bridge tower was erected on 2 June 2016.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> The last straight element of the Template:Convert straight section of the undersea tunnel was installed on 12 July 2016,<ref>Template:Cite web</ref> and the final tunnel joint was installed on 2 May 2017. Construction of the Main Bridge, consisting of a viaduct and an undersea tunnel was completed on 6 July 2017.<ref name="chinadaily7july2017">Template:Cite web</ref> The entire construction project was completed on 6 February 2018.<ref name="complete" /> During the construction 19 workers died.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>

Sections and elements

The Template:Convert HZMB consists of three main sections: the Main Bridge (Template:Convert) in the middle of the Pearl River estuary, the Hong Kong Link Road (Template:Convert) in the east, and the Zhuhai Link Road (Template:Convert) in the west of the estuary.<ref>Template:Cite news</ref><ref>Template:Cite web</ref>

Main Bridge

The Main Bridge, the largest part of the HZMB project, is a bridge-tunnel system constructed by the mainland Chinese authorities.<ref name="hkMainBridge">Template:Cite web</ref> It connects Zhuhai-Macao Port Artificial Island, an artificial island housing the Boundary Crossing Facilities (BCF) for both mainland China and Macau in the west, to the Hong Kong Link Road in the east.

This section includes a Template:Convert bridge construction and a Template:Convert immersed tube undersea tunnel that runs between two artificial islands, the Blue Dolphin Island on the west and the White Dolphin Island on the east.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> The bridge construction crosses the Pearl River estuary with three cable-stayed bridges spanning between Template:Convert, allowing shipping traffic to pass underneath.<ref>Website of Transport and Housing Bureau (HKSAR): "Cross boundary traffic: Hong Kong-Zhuhai-Macao Bridge" Template:Webarchive.

Template:See also Administered under Highways Department of HKSAR,<ref>Template:Cite journal</ref> the Hong Kong Link Road connects the main bridge-tunnel to an artificial island housing the Hong Kong Boundary Crossing Facilities (HKBCF). This section includes a Template:Convert bridge construction, a Template:Convert Scenic Hill Tunnel, and a Template:Convert at-grade road along the east coast of the Chek Lap Kok.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>

Zhuhai Link Road

The Zhuhai Link Road starts from Zhuhai-Macao Port Artificial Island, passes through the developed area of Gongbei via a tunnel towards Zhuhai, and connects to three major expressways, namely, the Jing-Zhu Expressway, Guang-Zhu West Expressway, and Jiang-Zhu Expressway.<ref>Template:Cite web</ref><ref>Template:Cite journal</ref>

Macau Bridge Link

Opened in October 2024, the Template:Convert bridge provides alternative access to Taipa Island from the HZMB boundary office.

Left- and right-hand traffic

Although the HZMB connects two left-hand traffic (LHT) areas, namely Hong Kong and Macau, the crossing itself is right-hand traffic (RHT), the same as in Zhuhai and other regions of mainland China (the bridge is technically in Zhuhai for most of its length<ref>Template:Cite news</ref>). Thus, drivers from Hong Kong and Macau need to make use of crossing viaducts to switch to RHT upon entering the bridge, and back to LHT upon leaving the bridge when they are back to Hong Kong and Macau.<ref>Template:Cite news</ref><ref>Template:Cite webTemplate:Dead link</ref> Traffic between Zhuhai and the bridge requires no left-right conversion as they are both RHT.<ref name="rightside">Template:Cite news</ref>

Transport

Shuttle buses

The OneBus Hong Kong Macau services

The HZMBus shuttle bus service (colloquially known as the "golden buses") runs 24 hours a day with bus departures as frequent as every five minutes.<ref>Template:Cite web</ref> The journey across the HZMB takes about 40 minutes.

The HZMB Hong Kong Port can be reached from Hong Kong by taxi or various buses including Cityflyer airport routes A10, A11, A12, A17, A21, A22, A23, A25, A26, A28 and A29, Long Win Bus airport routes A30, A31, A32, A33X, A34, A36, A37, A38, A41, A41P, A42, A43, A43P, A46 and A47X, NLB airport route A35 and overnight airport route N35, Green Minibus route 901, the B4 shuttle bus from Hong Kong International Airport, the B5 shuttle bus from Sunny Bay MTR station, or the B6 or B6S bus from Tung Chung.<ref>Template:Cite web</ref> In addition, all overnight airport buses (NA-prefixed routes) which are operated by Cityflyer or Long Win stops or terminates at the Hong Kong Port.

The HZMB Zhuhai Port can be reached from Zhuhai by taxis or the L1 bus which uses historic tourist vehicles, or Line-12, 23, 25 or 3 buses.<ref>Template:Cite web</ref>

The HZMB Macau Port can be reached from Macau by taxis or various buses including the 101X bus and the 102X bus from St Paul's and Taipa, or the HZMB Integrated Resort Connection bus from Taipa Ferry Terminal or the Exterior Ferry terminal, connecting with free casino shuttle buses.<ref>Template:Cite web</ref>

Private vehicles

Driving a car on the HZMB would incur the same restrictions as existing cross-border traffic using other checkpoints such as Shenzhen Bay Port or Huanggang Port. These include applying for separate driving licenses for both Hong Kong and mainland China, a Hong Kong Closed Road Permit for cross-boundary vehicles, and an Approval Notice from the Guangdong Public Security Bureau.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> Vehicle owners also need to ensure they have the appropriate insurance coverage for the regions they are travelling to.<ref>Template:Cite web</ref>

Hong Kong and Macau are densely populated cities that mostly rely on public transport and discourage excessive private vehicle usage. The Hong Kong government imposes significant fees, taxes and administrative paperwork on private vehicle ownership and usage to deal with road congestion within the HKSAR.<ref>Template:Cite web</ref> In addition, to help compact Macau tackle its road congestion problems, drivers arriving from other regions are strongly encouraged to use a park and ride scheme, leaving their vehicles at a car park on the edge of Macau. A small quota of 300 vehicles are allowed to enter Macau directly.<ref>Template:Cite web</ref><ref>Template:Cite news</ref> As such by the end of 2017 only 10,000 permits for private vehicles to drive across the HZMB from Hong Kong to Zhuhai had been issued.<ref>Template:Cite news</ref> In addition, the number of vehicles permitted to enter Hong Kong and Macau from other regions is subject to a daily quota.<ref>Template:Cite web</ref>

In late 2023 the permit/quota system relaxed further, allowing more Hong Kong and Macau vehicles to enter Guangdong Province via the Northbound Travel scheme.<ref>Template:Cite web</ref> A similar Southbound Travel scheme is planned for 2025.

Economic effects

The HZMB links three major cities—Hong Kong, Zhuhai, and Macau—which are geographically close but separated by water. With the bridge in place, travelling time between Zhuhai and Hong Kong was cut down from about 4 hours to 30 minutes on the road.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>

The HZMB project is part of a Beijing-driven strategy to create an economic hub and promote the economic development of the whole area of the Pearl River Delta, which is also known as Greater Bay Area.<ref>Template:Cite news</ref> Hoping to leverage the bridge and create an economic zone linking the three cities, Zhuhai's Hengqin area was designated as a free trade zone in 2015.<ref name="asia.nikkei.com" />

Controversies

Usage

Some residents in Hong Kong have complained of the restrictive cross-border criteria and large amount of administrative paperwork needed in order to use the bridge with their own private vehicle during the initial opening of the bridge as a hindrance to its use.<ref>Template:Cite news</ref> During the initial operation of the HZM bridge, it was criticized for low usage and not meeting traffic projections. The first day less than 1,500 private cars and goods vehicles crossed the bridge.<ref name=":1">Template:Cite web</ref> This is in contrast to the government prediction of 9,200 to 14,000 vehicles per day to cross the bridge.<ref name=":1" /> However this figure grew to an average of 8,900 private vehicles per day using the bridge in 2023.<ref>Template:Cite web</ref>

By 2024, over 10,000 private, coach and goods vehicles cross the HZM Bridge everyday.<ref>Template:Cite web</ref> In addition, most of the bridge's traffic is carried on frequent shuttle buses, this is reflected in the high passenger traffic figures crossing the bridge relative to the volume of private vehicles, with over 75,000 passengers crossing the bridge per day in 2024.<ref>Template:Cite web</ref>

On 31 January 2025, the Zhuhai port of the bridge reported a new record of 156,000 passenger trips in a single day, a new record since the bridge's opening.<ref name="star">Template:Cite web</ref>

Delays and budget overruns

The artificial island housing the Hong Kong Boundary Crossing Facilities (HKBCF) was reported drifting due to an unconventional method, hitherto unused in Hong Kong, for land reclamation using a row of circular steel cells pile-driven into the mud and filled with inert material to form a seawall.<ref>Template:Cite magazine</ref>

The drifting of parts of the reclaimed island allegedly caused a delay in the HZMB project. The Highways Department denied various reports of movement up to Template:Convert but admitted that parts of the reclaimed land had moved "up to six or seven metres",<ref>Template:Cite news</ref><ref name="hkfp1">Template:Cite news</ref><ref>Template:Cite news</ref> claiming that some movement was expected and safety had not been jeopardised.<ref>Template:Cite news</ref>

Mainland contractors also reportedly had difficulty constructing immersed tubes for their section of the project, with the director of the Guangdong National Development and Reform Commission stating that 2020 would be a difficult target to meet.<ref name="hkfp1" />

By 2017, the Main Bridge of the HZMB project had experienced a cost overrun of about ¥10 billion, blamed on increased labour and material costs, as well as changes to the design and construction schemes.<ref>Template:Cite news</ref>

Worker deaths and injuries

The number of deaths and injuries during the construction project came under scrutiny in Hong Kong. In addition to nine fatalities on the mainland side,<ref>Template:Cite news</ref> more than ten deaths were reported on the Hong Kong side of the construction project, plus between 234 and 600 injuries, depending on the source.<ref name="slam">Template:Cite news</ref> In April 2017, the Construction Site Workers General Union, the Labour Party and the Confederation of Trade Unions demonstrated at the Central Government Complex, demanding the government take action.<ref name="regrets">Template:Cite news</ref>

Lawmaker Fernando Cheung also expressed concern over the unknown death toll on the Chinese side of the project, speculating: "the project is known as the 'bridge of blood and tears' and we are only talking about the Hong Kong side. We don't even know what is happening in China. I suppose the situation could be 10 times worse than that in Hong Kong." He said that the Hong Kong Government had a responsibility to consider worker safety on the Chinese side.<ref name="regrets" />

Faked safety testing

In 2017, Hong Kong's Independent Commission Against Corruption (ICAC) arrested 21 employees (2 senior executives, 14 laboratory technicians, and 5 laboratory assistants) of Jacobs China Limited, a contractor of the Civil Engineering and Development Department for falsifying concrete test results, thus potentially risking the safety of the bridge for public use.<ref name="fakelab">Template:Cite news</ref> In December 2017, a lab technician pleaded guilty and was sentenced to imprisonment for eight months, while the others await sentencing. Hong Kong's Highways Department conducted tests again after the falsified results were exposed and found all test results met safety standards.<ref name="labtechnician">Template:Cite news</ref>

Seawall integrity

In April 2018, the public and media raised questions over the integrity of the seawalls protecting the artificial islands at both ends of the undersea tunnel. In footage taken by drone users and mariners, the dolosse installed at the edges of the artificial islands appear to have dislodged. Some civil engineers suggested that there was an error in design.<ref name="bridgeproblem">Template:Cite news</ref><ref name="illusion">Template:Cite news</ref> In dismissing the safety concerns, the HZMB Authority said the dolosse were designed to be submerged and the design was working as intended.<ref>Template:Cite news</ref> Director of Highways Department Daniel Chung denied on 8 April 2018 that the breakwater components had been washed away by waves.<ref>Template:Cite news</ref>

Subsequent aerial footage posted online showed a section of the dolosse breakwater completely underwater. Civil engineer So Yiu-kwan told Hong Kong media on 12 April 2018 that the water level, at the time the photos were taken, was about 1.74 mPD (metres above Principal Datum), but the maximum water level could reach 2.7 mPD. He said the dolosse would offer no wave protection if entirely submerged, and further alleged that they had been installed backwards.<ref name="underwaterhightide">Template:Cite news</ref>

Impact on wildlife

Conservationists at WWF Hong Kong blamed the construction of the HZMB for the falling number of white dolphins in the waters near the bridge.<ref>Template:Cite news</ref> The dolphins found near waters of Lantau were worst hit with numbers dropping by 60 percent between April 2015 and March 2016.<ref>Template:Cite news</ref>
