He was speaking following the completion by consultants of the environmental impact assessment for Hong Kong's Highways Department. The environmental impact assessment covered the 130ha artificial island that will house the HK boundary crossing facilities, the 12-kilometre Hong Kong Link Road and the 9km Tuen Mun-Chek Lap Kok Link.

The consultants considered many factors before selecting a site for the HK boundary crossing facilities, which will be at the north-east waters off the Airport Island. Plans for the Hong Kong Link Road have also been altered to accommodate residents' concerns about the visual impact of a sea viaduct at the Tung Chung seafront.

The bridge is due for completion by 2015-16.
