A design-build contract worth an equivalent of €1.15 billion (US$1.5 billion) is awarded by the Hong Kong Government to a joint venture of Dragages Hong Kong and Bouygues Travaux Publics, two subsidiaries of Bouygues Construction of France, for a new 4.2km undersea road tunnel in Hong Kong to link Tuen Mun in the New Territories on the mainland, with Hong Kong's Chek Lap Kok Airport on Lantau Island (Figs 1 and 2).

The TM-CLKL will become a 4.2km twin-tube subsea tunnel, with two traffic lanes in each 14m diameter tube. The project also includes construction of two cut-and-cover approach tunnels of 530m and 670m. The new tunnel link to Lantau Island (TM-CLKL) will connect the New Territories to the eastern end of the Hong Kong Link Road. Delivery of the civil works is scheduled for the end of 2018. More than 1,000 employees will be working on the project at peak periods.
