On June 30th, 2024, the Shenzhen-Zhongshan Link (the Link) officially opened to traffic. The Link carried over 720,000 vehicle trips in the first week of operation, surged to nearly 3 million in its first month, and has since accumulated more than 31 million vehicle trips over the past year. As of June 30th, 2025, the average daily traffic reached 86,000 vehicle trips, with a single-day peak of 181,600 vehicles.

The immersed tube undersea tunnel of the Shenzhen-Zhongshan Link spans 6.8 kilometers, with a 6-kilometer descent from the bridge deck to the sea level. Under normal conditions, vehicles take about 15 minutes to traverse the Link; during peak traffic, travel time can extend to approximately 50 minutes.

Within one month of opening, Zhongshan's tourism revenue hit 2.37 billion yuan, marking a 65.16% year‑on‑year increase. In 2024, Shenzhen and Zhongshan saw nearly 80% growth year-over-year in technology contract transactions.

Over its first year, traffic flow on the Link has remained orderly, and driving through the Link takes about 15 minutes outside of major holidays. The Link has helped ease traffic congestion around the Pearl River estuary, with cross-river vehicle flow growing by 15%.

Since the opening, two cross-city bus lines connecting Shenzhen and Zhongshan have been launched, operating around 100,000 trips in total and transporting approximately 2.8 million passengers, with an average of about 7,000 passengers per day.

Cross-border transport routes from Zhongshan to Hong Kong increased by 37.5% to 11 routes. Daily passenger departures average around 1,655, an increase of 47.2% compared to those before the Link opened.

Over 940,000 passengers from the western bank of the Pearl River estuary traveled to Shenzhen to take a flight, a rise of more than 160% compared with pre-opening levels.

In 2024, technology transactions between Shenzhen and Zhongshan reached nearly  100 million yuan (an 80% year-on-year rise). More than 20 projects, with investment exceeding 5 billion yuan, were launched in Zhongshan Cuiheng New District. Additionally, 34 projects each worth over 100 million yuan were secured in Jiangmen, and Taishan attracted 24 industrial transfer projects with a total investment of 6.05 billion yuan. Over 400 biopharma enterprises, including AscenPower, have settled in Nansha. At the 2024 Nansha Global Investment Promotion and Talent Attraction Conference, more than 1,400 enterprises participated, of which more than 30% were from Shenzhen.

These figures underscore the powerful momentum driving integration across the Guangdong-Hong Kong-Macao Greater Bay Area.
