Hongqimen Grand Bridge is 1,126 meters long and 43.2 meters wide and has a 520-meter main span. It is a double-tower, double-cable-plane semi-floating steel box girder cable-stayed bridge and its main towers have octagon sections and are topped with a kapok tree-shaped crown.
The west main tower is 176 meters tall. During construction, the engineering rail was optimized which shortened the construction period and improved engineering safety.

The Nansha-Zhongshan Expressway is a key traffic infrastructure in the Guangdong-Hong Kong-Macao Greater Bay Area. Once operational, it will shorten the round trip between the Nansha District of Guangzhou and Zhongshan to 30 minutes.
