Airport Tung Chung Link Project

Airport Authority Hong Kong (AAHK) first put forward its vision to transform Hong Kong International Airport (HKIA) into an Airport City in the “From City Airport to Airport City” report published in 2019.  The Airport City vision envisages growing HKIA’s position as the preeminent international aviation hub in Asia Pacific, while transforming HKIA into a new landmark and one of the key economic growth engines for Hong Kong.  To realise the Airport City vision, AAHK has adopted a strategy to fully capitalise on the unique geographical advantage of HKIA and capture opportunities arising from the new infrastructures connected to the airport, such as the Hong Kong-Zhuhai-Macao Bridge (HZMB). 

The commissioning of the HZMB in 2018 has greatly improved the connectivity between Hong Kong and cities in the Greater Bay Area (GBA), and further expand the catchment area of HKIA as the region’s leading international aviation hub.  To meet the growing demand and extend the airport’s reach, AAHK will continue to strengthen HKIA’s capacity for passenger and cargo service, through the expansion into a Three-runway System (3RS) and other capacity enhancement plans.  In addition, AAHK is introducing a growing cluster of functional enhancements with a view to transforming the airport into a new landmark and attracting more visitors to the Airport City from within Hong Kong, the GBA and other parts of Asia.  Such functional enhancements include SKYCITY, a major integrated development that comprises retail complexes, dining areas, hotels, leisure and entertainment facilities, as well as AsiaWorld-Expo (AWE) future developments and other related plans, with complementary infrastructural support and technological innovations. 

The infrastructural support to the airport’s capacity and functional enhancements includes, among others, a series of AAHK’s recommendations for land uses on the Hong Kong Port (HKP) (formerly known as Hong Kong Boundary Crossing Facilities) Island of HZMB. The key project items include the building of automated car parks for transit air passengers and visitors travelling via HZMB, and the Airportcity Link, a vehicular and pedestrian bridge, on which the AAHK operates an autonomous transportation system to connect HKP Island and SKYCITY, and plans to extend such system to Tung Chung Town Centre. In addition, land parcels on the HKP Island have been reserved for the development of air cargo logistics.

Under the strategic context as discussed above, the Airport Tung Chung Link Project (hereafter referred to as the “Project”) is proposed. The Project involves the construction and operation of (i) a proposed Airport Tung Chung Link (hereafter referred to as ATCL) to connect HKP Island, Airport Island and Tung Chung Town Centre via a dedicated road link, with the use of an autonomous transportation system (supported by zero emission vehicles); and (ii) marine facilities in the waters between Airport Island and HKP Island, including a pier and berthing facilities to serve pleasure vessels and to provide marine transport services associated with tourism.The construction period of the marine facilities and ATCL spur line will be updated further in subsequent stage.

An Environmental Permit (EP No. EP-630/2023) for the construction and operation of the ATCL Project was first granted to AAHK in October 2023 in accordance with the EIAO based on the approved EIA report for the ATCL Project. Subsequently an application for variation of the EP was submitted on 3 November 2025 and the current valid EP (No. EP-630/2023/A) was issued by EPD on 1 December 2025. Under the requirements of the EP, the AAHK is required to set up a dedicated website for placing relevant environmental monitoring data and the project information. This website contains the Project Background, EIAO Documents, EP Submissions, Baseline Monitoring Report, EM&A data and EM&A Reports.
