The Langqi Minjiang Bridge is 2675 meters long, the main bridge is 1280 meters long, and the main bridge deck is 28.7 meters wide. Under the bridge, 30,000-ton seagoing ships can be navigable. The main bridge is designed as a twin-tower equal-height cable-stayed bridge with a main span of 680 meters, and the main span length ranks among the top 10 similar bridges in the world. After the Langqi Minjiang Bridge is completed, the central area of Fuzhou Economic and Technological Development Zone can directly enter Langqi through the bridge. With the further improvement of the surrounding road network in the future, the distance from the central city of Fuzhou to Langqi Island will also be shortened to about 23 kilometers. The time can be shortened to about 20 minutes, thus greatly shortening the distance between Langqi and the central urban area of Fuzhou, further highlighting Langqi's location advantage at the mouth of the Minjiang River, and laying a solid foundation for Langqi's great development, great development and great leap.
