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. China's central government showed support for this project on 30 December 1997. 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.

Preparation

To coordinate the project, the Advance Work Coordination Group of HZMB was set up in 2003.

Sections and elements

The HZMB consists of three main sections: the Main Bridge () in the middle of the Pearl River estuary, the Hong Kong Link Road () in the east, and the Zhuhai Link Road () in the west of the estuary.


Main Bridge

The Main Bridge, the largest part of the HZMB project, is a bridge-tunnel system constructed by the mainland Chinese authorities. 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 bridge construction and a

Hong Kong Link Road

Administered under Highways Department of HKSAR, 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 bridge construction, a Scenic Hill Tunnel, and a at-grade road along the east coast of the

.


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.


Macau Bridge Link

Opened in October 2024, the bridge provided 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). 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. Traffic between Zhuhai and the bridge requires no left-right conversion as they are both RHT.


Transport


Shuttle buses

The HZMBus shuttle bus service (colloquially referred as the "golden buses") runs 24 hours a day with bus departures as frequent as every five minutes. 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, 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. 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. 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.


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. Vehicle owners also need to ensure they have the appropriate insurance coverage for the regions they are travelling to. 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. 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 A park and ride, also known as incentive parking or a commuter lot, is a parking lot with public transport connections that allows commuters and other people heading to city centres to leave their vehicles and transfer to a bus, Rail transport, r ...
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. 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. In addition, the number of vehicles permitted to enter Hong Kong and Macau from other regions is subject to a daily quota. 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. 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. The HZMB project is part of a

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. 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. This is in contrast to the government prediction of 9,200 to 14,000 vehicles per day to cross the bridge. However this figure grew to an average of 8,900 private vehicles per day using the bridge in 2023. By 2024, over 10,000 private, coach and goods vehicles cross the HZM Bridge everyday. 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. 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.https://www.thestar.com.my/aseanplus/aseanplus-news/2025/02/02/hong-kong-zhuhai-macau-bridge-sees-record-daily-passenger-trips


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. 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 but admitted that parts of the reclaimed land had moved "up to six or seven metres", claiming that some movement was expected and safety had not been jeopardised. 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. 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.


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, 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. In April 2017, the Construction Site Workers General Union, the Labour Party and the Confederation of Trade Unions demonstrated at the

, demanding the government take action. 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.


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. 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.


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
dolos A dolos (plural: dolosse) is a wave-dissipating concrete block used in great numbers as a form of coastal management. It is a type of tetrapod. Weighing up to , dolosse are used to build revetments for protection against the erosive force of w ...
se installed at the edges of the artificial islands appear to have dislodged. Some civil engineers suggested that there was an error in design. In dismissing the safety concerns, the HZMB Authority said the dolosse were designed to be submerged and the design was working as intended. Director of Highways Department Daniel Chung denied on 8 April 2018 that the breakwater components had been washed away by waves. 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.


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. The dolphins found near waters of Lantau were worst hit with numbers dropping by 60 percent between April 2015 and March 2016.
