The Tuen Mun–Chek Lap Kok Link (Chinese: 屯門至赤鱲角連接路, abbreviated as TM–CLKL) is a road project under construction in the New Territories, Hong Kong. It comprises two elements: the "Northern Connection" and the "Southern Connection". The Northern Connection comprises an undersea tunnel crossing the Urmston Road, linking Tuen Mun to the "Boundary Crossing Facilities" (BCF), an artificial platform connected to Chek Lap Kok Airport. The Southern Connection comprises viaducts linking the BCF to North Lantau Highway on Lantau Island.

Though the project lies entirely within Hong Kong territory, its construction is associated with the new Hong Kong–Zhuhai–Macau Bridge. The estimated cost of the design, site investigation, and construction of the TM–CLKL (including associated works, like land reclamation) is about HK$46.71 billion. The project is expected to be fully commissioned by 2020.[1]

History

The contract to construct the Northern Connection tunnel (No. HY/2012/08) was awarded on 26 July 2013 to the Dragages-Bouygues Joint Venture. It commenced on 5 August 2013.[2]

Design

The tunnel portion will be approximately five kilometres in length. It will carry a two-lane dual carriageway.[1]

Construction

The dual sub-sea tunnels are being bored up to 55 metres below sea level using the Tuen Mun - Chek Lap Kok TBM, the world's largest tunnel boring machine.[3]

Originally scheduled for opening in 2018, completion of the link has been delayed at least two years. It is now expected to open in 2020 at the earliest.[4][1]
