Brief introduction of Lingdingyang bridge in deep middle passage

Lingdingyang Passage starts from Qianhai, Shenzhen, Guangdong, crosses Lingdingyang, passes through Qi 'ao Island, Zhuhai, then reaches Tangjia, continues westward, passes through Wugui Mountain in Zhongshan, reaches Lianzhou and Doumen, and extends westward to Gaolan Port, Jiangmen Taishan, Yangjiang and cities in western Guangdong.

Lingdingyang Bridge is an integral part of the deep middle passage under construction, similar to the Hong Kong-Zhuhai-Macao Bridge. It is a super bridge project integrating bridges, artificial islands and subsea tunnels. Although it is not as long as the Hong Kong-Zhuhai-Macao Bridge, it plays an important role in bridge technology and significance. Lingdingyang Bridge is an important node of the deep middle passage, which will start from the land in Shenzhen and extend westward to Dingling.

Compared with Hong Kong-Zhuhai-Macao Bridge, Lingdingyang Bridge has no advantage in overall length, but its transportation capacity is stronger than that of Hong Kong-Zhuhai-Macao Bridge. The Hong Kong-Zhuhai-Macao Bridge adopts a two-way six-lane design with only three lanes on each side, while the Lingdingyang Bridge adopts a two-way four-lane design with a total of eight lanes. Not only that, the bridge can also pass through heavy trucks weighing dozens of tons, which is more convenient for local transportation.

General situation of Lingdingyang waterway:

Lingdingyang waterway is an important waterway connecting the east and west banks of the Pearl River. The main bridge is 20km away from the upper deep passage 12km and the lower Hong Kong-Zhuhai-Macao Bridge. It starts from Shenzhen Qianhai in the east, passes through Qi 'ao Island, and reaches Zhuhai-Zhuhai Expressway Interchange in the west, with a total length of about 47km, of which Qi 'ao Island and Zhuhai-Zhuhai Expressway Interchange are about 15km. For the river-crossing section, it is suggested to adopt the scale of two-way eight-lane expressway+four-line railway, and the design speed of the highway is100 km/h; The construction form adopts the bridge and tunnel scheme of "West Bridge and East Tunnel".

After landing from Qi 'ao Island on the west bank of the Pearl River Estuary, Lingdingyang Passage will set up 13 interchange, which will connect Zhuhai Qi 'ao Bridge, Qin Jin Expressway, West Coast Expressway, Zhu Jiang Expressway, Airport Expressway, Gaolan Port Expressway and Zhongshan Expressway respectively.
