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 in the New Territories, Hong Kong. It comprises two elements: the “Northern Connection” and the “Southern Connection”. The Northern Connection comprises of an undersea tunnel crossing the Urmston Road, linking Tuen Mun to the “Boundary Crossing Facilities” (BCF), an artificial peninsula connected to Hong Kong International Airport. The Southern Connection, officially named Shun Long Road (Chinese: 順朗路), comprises viaducts linking the BCF to North Lantau Highway on Lantau Island.
The construction of the link has helped facilitate travel between the Northwest New Territories (Tuen Mun and Yuen Long Districts) and the Hong Kong International Airport and the Hong Kong-Zhuhai-Macau Bridge (Hong Kong Port).
The tunnel portion is a two-lane dual carriageway approximately 5 kilometres long. The dual sub-sea tunnels were bored up to 55 metres below sea level using the Tuen Mun – Chek Lap Kok TBM, the world’s largest tunnel boring machine.
Originally scheduled for opening in 2018, completion of the link had been delayed for two years. It opened to traffic on 27 December 2020.
