​     The Highways Department (HyD) today (June 29) signed a works contract with the Gammon Construction - Build King - Tung Lee Joint Venture for the Widening of Yuen Long Highway (Section between Lam Tei Quarry and Tong Yan San Tsuen Interchange), marking the official commencement of the construction stage of the HyD's first strategic road infrastructure project for the Northern Metropolis, fully supporting its long-term development.

​     The scope of works mainly comprises the widening of an approximately 3-kilometre-long section of Yuen Long Highway between Lam Tei Quarry and Tong Yan San Tsuen Interchange from a dual three-lane carriageway to a dual four-lane carriageway; the widening of a section of the slip road connecting Hung Tin Road (southbound) and Yuen Long Highway (eastbound) from a single-lane carriageway to a two-lane carriageway; and the construction of noise barriers with a total length of approximately 2.1km to mitigate the traffic noise impact on nearby residents.

​     During the planning and design stages, the project team had been seeking more cost-effective construction methods, including optimising the design of retaining walls and noise barriers to reduce construction costs, minimise the scale of works and shorten the construction period. The project team will continue to uphold a proactive and innovative mindset and closely collaborate with the contractor. While ensuring the safety and quality of works, the team will strive to control the cost, enhance construction efficiency, and minimise the impact on nearby residents and existing traffic during construction.

​     The estimated total contract sum is about $1.37 billion, with targeted completion in 2031. Upon completion of the project, the overall traffic capacity of this section of Yuen Long Highway will be substantially enhanced to meet the traffic demands of the Northern Metropolis (including the Hung Shui Kiu/Ha Tsuen New Development Area and Yuen Long South New Development Area in the Northwest New Territories), delivering substantial benefits to the development of the Northern Metropolis.
