During the May Day holiday, the reconstruction and expansion of Zhongshan-Jiangmen Highway remained in full swing.

"Nearly 2,000 builders spare no efforts to advance the construction efficiently on the frontline," said the project leader.

To date, 97% of the subgrade construction, 80% of the bridge construction and 47% of the pavement construction have been completed.

The project, scheduled to open to traffic in 2024 synchronously with the Shenzhen-Zhongshan Bridge, will promote the integrated economic development of Zhongshan and Jiangmen.
