Project description項(xiàng)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.瑯岐閩江大橋長(zhǎng)2675米，主橋長(zhǎng)1280米，主橋橋面寬28.7米，按雙向4車(chē)道加緊急停車(chē)帶設(shè)計(jì)，預(yù)留雙向6車(chē)道。橋下可通航3萬(wàn)噸級(jí)海輪。主橋設(shè)計(jì)為主跨680米長(zhǎng)的雙塔等高斜拉橋，主跨長(zhǎng)度居世界同類(lèi)橋梁前10名。瑯岐閩江大橋建成后，從福州經(jīng)濟(jì)技術(shù)開(kāi)發(fā)區(qū)中心區(qū)可直接通過(guò)該橋進(jìn)入瑯岐，隨著今后周邊路網(wǎng)的進(jìn)一步完善，福州中心城區(qū)至瑯岐島的距離也將縮短到23公里左右，行車(chē)時(shí)間可縮短至20分鐘左右，從而大大拉近瑯岐與福州中心城區(qū)的距離，進(jìn)一步凸顯瑯岐在閩江口的區(qū)位優(yōu)勢(shì)，為瑯岐大開(kāi)發(fā)、大發(fā)展、大跨越奠定堅(jiān)實(shí)基礎(chǔ)。施工單位為中交二航局、中鐵大橋局。
