The $18.7 billion Tung Chung Extension was gazetted at the end of last year and is expected to be completed in 2029.
The works involve the addition of Tung Chung East Station at a position about 2 kilometers in front of the existing Tung Chung Station, and the extension of the Tung Chung Line to the west by about 1.3 kilometers, with Tung Chung West Station as the new terminus.
The latest environmental impact assessment report of the Tung Chung Extension shows that the engineering consultant has considered 3 options for the station location and alignment of Tung Chung West Station, so as to avoid the sites of archaeological research value at Ma Wan Chung, as well as mangroves and mudflats. and other ecological environment.
According to the current preliminary design plan, tunnel boring machines will be used to excavate train tunnels at least 10 meters below the ground in Ma Wan Chung Village to reduce the impact on trees, fisheries and cultural heritage.
However, the EIA report pointed out that within the scope of the project assessment, there are 14 types of habitats, and there are also species of conservation value such as L.
There are also declared monuments within the area, and it is expected that the Kadoorie Agricultural Auxiliary Society's stone monument and architectural cultural relics will need to be relocated or demolished.
The MTR said that it had considered 3 routing schemes during the design, and the final scheme (red dotted line) could avoid mangroves and other archaeological sites, but some private land had to be recovered.
(EIA Report of Tung Chung Extension Line)
The MTR pointed out in the EIA report that it had considered 3 routes from Tung Chung Station to Tung Chung West Station, and the location of the stations would be different.
One of the proposed routes is to start from Tung Chung Station, go south first and then turn west, bypass North Lantau Hospital, and set up a station at Yu Tung Road.
The MTR pointed out that although the alignment can avoid the ecological resources of Ma Wan Chung located near the northwest, there is no need to reclaim the private land.
However, this line may have potential electromagnetic interference to the North Lantau Hospital, and despite good site practices, it may exceed the vibration limit transmitted by the North Lantau Hospital through the ground.
The proposal to set up a station near Yu Taiyuan is described as "unattractive"
Another plan is to set up a station on Song Yan Road between North Lantau Hospital and Yat Tung Village, near Yu Tai Court. This plan can also avoid damage to ecological resources, but the proposed plan's location of Tung Chung West Station cannot cover the target. Scope of services, and described "the solution is not attractive".
The route selected as the first choice will pass in the north of Ma Wan Chung Village and loop back to the west of Yat Tung Village to set up a station.
The MTR pointed out that the project plans to use tunnel boring machines to excavate tunnels, avoiding mangroves, mudflats, forests, and most sites of Ma Wan Chung with archaeological research value, but the proposed location of the station needs to recover some private Orchards, and through a small part of Ma Wan Chung underground.
According to the EIA report, tunnel excavation can avoid marine engineering and direct air, noise, water quality and other pollution.
The proposed scheme will set up tunnel boring machines near the banks of Tung Chung Bay to excavate a tunnel at least 10 meters below the ground of Ma Wan Chung Village. A barge transfer facility will also be set up at the north of Tung Chung Hoi An Road, with an area of about 13,000 square meters. , for transporting construction waste.

Lu's little tree frog was found outside the construction site
The report pointed out that a total of 14 types of habitats, including coastal waters, have been identified within the scope of the assessment.
A variety of species with conservation value have been recorded within the assessment area, including Lu's little tree frog found outside the construction site, as well as Agarwood and Agaricus serrata.
The tunnel of Tung Chung West Station will pass through Ma Wan Chung Village and other sites of archaeological value. The EIA report pointed out that the on-site archaeological exploration of Tung Chung West Station has been carried out, and no serious archaeological impact is expected. The location of the tunnel line has not been explored. It is recommended that further exploration be conducted by archaeological experts before construction.
The MTR pointed out that since the excavation using the tunnel boring machine is mainly carried out in the rock layer, it is expected that the vibration will be slight, but it will not cause land subsidence and vibration, which will cause serious impact on archaeology.

It is expected that the stone tablet of the Kadoorie Agricultural Auxiliary Society will need to be relocated or demolished
The report pointed out that there are two declared monuments within the survey area, including Tung Chung Fort and Tung Chung Small Fort, and two Grade II historic buildings, namely Tung Chung Hau Wong Temple and Tung Chung Tin Hau Temple.
According to the report, the relevant construction works include the construction of Tung Chung West Station, emergency access buildings, related workshops, barge transfer facilities and tunnel alignment. Affected.
According to the government’s previous introduction, the Kadoorie Agricultural Auxiliary Society had provided agricultural and animal husbandry support to the villagers in the Lantau area at that time. In each village, there would be farmhouses, ponds, etc. written with KAAA, which means that the Auxiliary Society was funded and built for the development of Hong Kong’s agriculture. symbols of.
Tung Chung East Station Design Must Consider Tung Chung New Town Expansion Plan Landscape Corridor
As for Tung Chung East Station, as it is located on the reclaimed land within the Tung Chung New Town Extension Plan, ecological and archaeological considerations are less, but the landscape corridor of the Tung Chung New Town Extension Plan must still be maintained.
The MTR expects to start the construction of Tung Chung East Station in the second quarter of 2023, the tunnel excavation entrance near Tung Chai Wan, and the construction of Tung Chung West Station. Construction will be completed in the first quarter and the fourth quarter of 2027.
