  Tuen Mun ﹣Chek Lap Kok Link
  Tuen Mun – Chek Lap Kok Link (TM-CLKL) will provide a strategic link connecting the Northwest New Territories (NWNT) with the Hong Kong – Zhuhai – Macao Bridge Hong Kong Boundary Crossing Facilities (HKBCF), North Lantau and the Hong Kong International Airport (HKIA).

The total length of this new route is about 9km long, consisting of two sections: Northern Connection and Southern Connection. For Southern Connection, it will connect North Lantau Highway (NLH) at Tai Ho and the HKBCF situated at the northeast waters off the HKIA. For Northern Connection, it will connect the HKBCF and Tuen Mun Area 40 adjacent to the Tuen Mun River Trade Terminal and join Lung Mun Road and Lung Fu Road near Butterfly Beach through the toll plaza at Tuen Mun Area 46.

The TM-CLKL will reduce the journey time between NWNT and Lantau. As compared to the current route, the traveling distance between Tuen Mun South and HKIA will be reduced by about 22 km. The traveling time will also be shortened from 30 minutes to 10 minutes. This new road link not only helps divert traffic flows to relieve the existing traffic conditions of NLH, Lantau Link and Tuen Mun Road, but also provides as an alternative route to the HKIA, thus reinforcing the HKIA as a regional aviation hub.

Upon commissioning of TM-CLKL, residents of Tuen Mun, Yuen Long and NWNT will have a direct and convenient route to Lantau (including the HKIA and Tung Chung).
 
 
  Scope
  The TM-CLKL comprises a 9 km long dual 2-lane carriageway between Tuen Mun South and North Lantau, and is divided into two major sections: Southern Connection and Northern Connection.

Southern Connection will connect NLH at Tai Ho and the HKBCF via land viaducts of about 1.9 km long and sea viaducts of 1.6 km long while Northern Connection will link the HKBCF and Tuen Mun Area 40 by a sub-sea tunnel of about 5 km long crossing the Urmston Road (please visit Project Uniqueness page for more details) and daylighting at a 16.5 ha reclamation just east of Tuen Mun River Trade Terminal. The alignment then runs on elevated structure over Lung Mun Road, through the toll plaza in Tuen Mun Area 46, and finally connects Lung Mun Road and Lung Fu Road near Butterfly Beach via slip roads and a roundabout.

In view of the mega scale of the project involving complex technical problem including tunnel boring below sea bed, close proximity to the HKIA, construction over important navigation channel, strategic road and railway, etc., various challenges and risks will be encountered during the implementation of the works.
 
 
  Programme
  According to the contractor's latest programme, it is anticipated that if no other unforeseen conditions arise in the future, all the works could be completed in the first half of 2019 at the earliest. Based on the latest situation, the HyD and the consultants are now carrying out a review on the completion date of the tunnel works contract. Based on a preliminary assessment, if the contractor is fully co‐operative and can complete a reasonable design amendment in a timely manner and expeditiously catch up with the work progress, the HyD and the consultants believe they can strive to complete the tunnel works contract in the end of 2019 at the earliest and all construction works of the TM‐CLKL Northern Connection in 2020.  
 
  Cost
