Technical Specifications

The Tuen Mun South Extension’s core civil engineering work involves the construction of a 2.4 km elevated viaduct running along the Tuen Mun River channel. This design minimizes the ground-level footprint in a dense urban area. The extension will add two new stations to the Tuen Ma Line: an intermediate station at Area 16 (A16) and a new terminus, Tuen Mun South Station, strategically located near the Tuen Mun Ferry Pier to facilitate multi-modal transport interchange.

Both stations are engineered to high sustainability standards, targeting BEAM Plus Gold certification. The design incorporates significant green technologies, including rooftop solar panels, extensive greening, and rainwater harvesting systems. Energy efficiency is prioritized through the use of natural ventilation and lighting, smart LED control systems, and speed-adjustable escalators. The project also necessitates complex brownfield works, including the re-provisioning of the Siu Hei Bridge and the conversion of the Wu Yuet Bridge for pedestrian and cyclist access.

Key Takeaways

  • Enhanced Urban Mobility: The extension directly addresses a significant transport gap in a densely populated area, projected to reduce travel times to central business districts by up to 12 minutes and alleviate chronic road traffic congestion.
  • Benchmark for Sustainable Infrastructure: The project sets a new standard for MTR developments with its mandated BEAM Plus certification and a target of 20% lower annual carbon emissions compared to conventional station designs, integrating green technologies directly into station architecture.
  • Community-Centric Development: Beyond transportation, the project incorporates significant community facility upgrades, including the enhancement of Wu King Road Garden, demonstrating a holistic approach to urban integration that minimizes disruption and improves local public spaces.
