On April 25^th, the general manager of BRDI Zhang Min signed the contract and made a speech at the contract-signing ceremony of Shenzhen-Zhongshan Bridge Project held in Guangzhou.

Shenzhen-Zhongshan Bridge is a cluster project composed of ultra-wide undersea tunnel, ultra-long span bridge, deepwater artificial island and underwater interchange. Featuring an unprecedented scale, unusually complicated construction conditions and record-high technical difficulties, it’s another world-class major cross-sea traffic engineering project that BRDI participated in construction after Hong Kong-Zhuhai-Macau Bridge.

Situated in the core area of the middle reaches of Pearl River Delta in Guangdong Province, Shenzhen-Zhongshan Bridge connects with Airport Interchange of Guangzhou-Shenzhen Yanjiang Expressway in the east, and extends to Hengmen Interchange of Zhongshan East Outer Ring Road and Zhongshan-Kaiping Expressway in the west. It’s a convenient connection of Shenzhen-Dongguan-Huizhou Economic Zone on the east bank of Pearl River Estuary with Jiangmen-Zhongshan-Zhuhai Economic Zone on the east bank of Pearl River Estuary. About 30km away from Humen Bridge in the north and 40km away from Hong Kong-Zhuhai-Macau Bridge in the south, Shenzhen-Zhongshan Bridge is important in completing the Pearl River Delta Expressway Network and improving the traffic safety on two banks of the Pearl River Delta.

Adopting expressway technical standards throughout the bridge, Shenzhen-Zhongshan Bridge will have a bridge and tunnel design at the speed of 100km/h. The dual eight-lane is designed to serve for 100 years. With a total length of 24.03km, the project is estimated to cost 42.371 billion yuan. BRDI has undertaken the survey and design task for Section B with a length of 6.9km.

Founded in 1950 upon the approval of the Government Administration Council for the construction of Wuhan Yangtze River Bridge, BRDI is the oldest specialized bridge design institute in China. For the past six decades, BRDI has surveyed and designed about 1,000 major bridges for highways, railways and municipal works, among which 30-plus are cross-sea bridges including Donghai Bridge, Hangzhou Bay Cross-sea Bridge, and Fuzhou-Pingtan Railway Pingtan Cross-sea Bridge. While, Donghai Bridge can be regarded as the first cross-sea bridge in China; Hangzhou Bay Cross-sea Bridge is the world’s third longest cross-sea bridge and Fuzhou-Pingtan Railway Pingtan Cross-sea Bridge is the first rail-cum-road cross-sea bridge in China.
