導(dǎo)語(yǔ):廣東:深中通道西人工島,“海上風(fēng)箏”成灣區(qū)新地標(biāo)。

"Super project" the west artificial island of shenzhen-zhongshan cross river channel, namely the west artificial island of shenzhen-zhongtong channel, is located on the sea surface of the pearl river estuary. The island covers an area of 137,000 square meters, equivalent to 19 international standard football fields. From the air, it looks like a giant kite flying over the pearl river estuary.

During the construction, the Chinese builders sent 57 giant steel cylinders up to 28 meters in diameter deep into the ocean floor, marking the "sea kite" in 141 days.

In addition, it will become a transfer junction between the deep - middle - channel offshore long-span bridge and subsea immersed tube tunnel.

As an important part of the transport infrastructure in the guangdong-hong kong-macao greater bay area, the construction of the shenzhen-middle channel will greatly alleviate the traffic pressure on both sides of the pearl river and promote the connectivity between 11 cities in the guangdong-hong kong-macao greater bay area.
