1              Introduction

 

1.1          Background

1.1.1      The Railway Development Strategy 2014 (RDS-2014) announced by the Government of the Hong Kong Special Administrative Region included the conceptual scheme of Tung Chung West (TCW) Extension and a possible Tung Chung East (TCE) Station.

1.1.2      This new railway system has been included in the approved Schedule 3 Environmental Impact Assessment (EIA) for Tung Chung New Town Extension (TCNTE), which has included the new stations at TCE area and TCW area and the associated trackwork and tunnel. However, a separate Schedule 2 EIA study for this railway system is conducted to address the associated environmental impacts, taking into account of the latest design.

1.1.3      The EIA Report for Tung Chung Line Extension (the Project) was approved on 12 July 2022 (Register No. AEIAR-235/2022). The Environmental Permet (EP) No. EP-614/2022 was then issued on 9 August 2022.

 

1.2          Project Programme

1.2.1      Two construction Works Contracts of the Project have been awarded since May 2023. The construction of the Project commenced in June 2023 and is expected to complete in 2029. Table 1.1 summarises the information of the awarded Works Contracts.
