Project description項目描述

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. The construction units are China Communications Second Navigation Bureau and China Railway Bridge Bureau.琅岐閩江大(dà)橋長2675米，主橋長1280米，主橋橋面寬28.7米，按雙向4車道加緊急停車帶設計，預留雙向6車道。橋下(xià)可通航3萬噸級海輪。主橋設計爲主跨680米長的雙塔等高斜拉橋，主跨長度居世界同類橋梁前10名。琅岐閩江大(dà)橋建成後，從福州經濟技術開發區中(zhōng)心區可直接通過該橋進入琅岐，随着今後周邊路網的進一(yī)步完善，福州中(zhōng)心城區至琅岐島的距離也将縮短到23公裏左右，行車時間可縮短至20分(fēn)鍾左右，從而大(dà)大(dà)拉近琅岐與福州中(zhōng)心城區的距離，進一(yī)步凸顯琅岐在閩江口的區位優勢，爲琅岐大(dà)開發、大(dà)發展、大(dà)跨越奠定堅實基礎。施工(gōng)單位爲中(zhōng)交二航局、中(zhōng)鐵大(dà)橋局。
