福州市区将建1.5公里跨江大桥 设置2处互通式立交、10条匝道_我的网站

A |     AI摘要      前横闽江大桥及接线工程可研获批，全长约1.5公里，连接仓山与台江。    (ECNS) -- An 11.6-kilometer offshore steel trestle bridge, the longest of its kind currently under construction in China, was fully connected on Tuesday in Dalian, located in China's northeastern Liaoning Province. The steel trestle bridge is a key supporting facility for the Dalian Changhai Bridge project.        Changhai County, China's only island border county, has long relied on maritime transport. However, ferry services are suspended for more than 60 days each year due to tides, strong winds and heavy fog, while round-the-clock navigation is unavailable even when services are operating.    These limitations have restricted residents' mobility and hindered local economic development.    The Changhai Bridge project stretches 25.5 kilometers across the Lichangshan Strait, linking Dachangshan Island in Changhai County with the mainland at Pikou Port in Pulandian District. Once completed, the bridge is expected to end the county's long-standing dependence on maritime transport.    Construction in the Yellow Sea has posed significant challenges due to frequent changes in wind, waves and tides, as well as shallow waters that prevent conventional construction vessels from operating.    To overcome these difficulties, the project team built the steel trestle bridge as a key support facility. Serving as the main transport route for construction materials, heavy machinery and personnel, it acts as a "lifeline" for offshore construction, according to the project team.    Ni Jiaming, project manager for the third section of the Changhai Bridge project under China State Construction Engineering Corporation (CSCEC), said the steel trestle bridge required 3,431 piles and 67,000 metric tons of steel. Construction was completed in 423 days, 10 days ahead of schedule.    Gong Baokai, deputy chief commander of the Dalian Changhai Bridge project under China State Construction Eighth Engineering Division, said completion of the trestle bridge has helped overcome construction difficulties in shallow waters, significantly improving the efficiency of transporting materials and personnel while reducing offshore construction risks. Its connection also marks the southern section of the Changhai Bridge project entering the main foundation construction phase.    The Changhai Bridge is expected to open to traffic in 2029.    (By Tang Yuxian)                    。项目将完善福州路网，缓解东部过江压力，提升通行效率。目前正开展初步设计，争取尽早开工。         近日，前横闽江大桥及其接线工程可行性研究报告获省发改委批复，同意建设。    项目起于福州仓山区雁头路，主线沿前横快速通道向北，高架桥上跨南江滨西大道，设置前横闽江大桥跨越闽江，后上跨北江滨中大道，终于台江区鳌峰路，与在建前横快速路高架桥衔接，并分别于南江滨大道、北江滨大道各设置1处互通式立交，南北桥头分别设置非机动车桥。

B | 项目全长约1.5公里，南江滨立交设置6条匝道，北江滨立交设置4条匝道，南北桥头非机动车桥长度分别为1.1公里、0.85公里。

C |     主线采用城市主干路标准建设，设计速度60公里/小时，规划红线宽度47米至60米，其中主线高架桥按双向六车道，前横闽江大桥按双向八车道；地面辅道设计速度40公里/小时。    根据批复，福州市有关部门将抓紧开展初步设计，深化其他相关前期工作，争取项目尽早开工建设。    项目的建设对完善福州骨干路网系统，加强福州二环、三环间路网密度，缓解福州东部过江通道交通压力，提高台江、仓山、晋安通行效率，促进福州经济社会发展等具有重要意义。（记者 赵铮艳）。
