China, Pearl River Delta - cn/71


  €2 billion toll bridge project announced to link Lantau Island in Hong Kong with Zhuhai and Macao, west of it. Two artificial islands linked together by a 1.4 km tunnel will be built in the middle of the delta to allow ship navigation. Main financier is Hopewell Group (50%). 37/03.Hong Kong's Highways Department appointed Arup to carry out a feasibility study for the Hong Kong section of the Hong Kong-Zhuhai-Macau bridge. The assignment involves preliminary design and an environmental impact assessment for about 12 km of bridge works that will be built in Hong Kong waters from Lantau Island. About 3 km of bridge could be replaced by a tunnel if the elevated structure is found to affect operations at nearby Hong Kong International Airport. The Hong Kong section will connect to the 30 km portion in mainland waters across the mouth of the Pearl River from Macau and Zhuhai.

From Zhuhai and Macau traffic would cross on a low-rise concrete bridge before descending into a tunnel under the Pearl River's main navigational channel before emerging close to Hong Kong waters. A low-rise bridge would be used to take traffic to the west coast of Lantau Island.
