On April 4, during the Chinese traditional Qingming Festival, traffic volume on the ShenZhong Link reached a new peak of 178,400 vehicle trips, according to the Guangdong Provincial Communications Group.

With a noticeable increase in people returning home for ancestral worship during the holiday, traffic heading from Shenzhen toward Zhongshan and western Guangdong surged significantly. The entire link operated under consistently high traffic levels, setting a new record since its opening.

The ShenZhong Link is the world's first infrastructure project combining a two-way eight-lane undersea tunnel, an underwater interchange, and a large-scale sea bridge complex. The transition between bridge and tunnel includes a 6-kilometer-long incline, adding to the engineering challenge. It officially opened on June 30, 2024. It is 24 kilometers long and can be reached from Shenzhen to Zhongshan in 30 minutes.
