The ShenZhong Link has seen a massive surge in traffic, carrying over 2 million vehicles since it was put into operation on June 30, the Guangdong Provincial Department of Transportation said on Saturday.

A total of 1.85 million passenger cars used the new infrastructure in south China's Guangdong Province, with trucks at 150,200, the department added.

Spanning 24 kilometers, the link handles an impressive daily average of over 100,000 vehicles, with 305,000 vehicles crossing it in the first 72 hours after its official opening.

The link starts at the Shenzhen airport interchange and connects with Ma'an Island in Zhongshan across the Pearl River, cutting the Shenzhen-Zhongshan travel time from two hours to approximately 30 minutes.

It is a key component of the national expressway network G2518, located approximately 30 kilometers south of the Humen Bridge and 31 kilometers north of the Hong Kong-Zhuhai-Macao Bridge.

"The link has already accounted for about 25 percent of the daily traffic passing through the Pearl River, which promotes market integration in the GBA," said Lin Feiming, head of the Guangdong Provincial Department of Transportation.
