Core Viewpoint - The construction of the rapid road network in Yantai is a key project in the city's comprehensive transportation system planning for 2023-2035, aiming to significantly improve urban spatial organization efficiency and achieve efficient travel goals by 2035 [1][24]. Group 1: Project Overview - The rapid road network includes multiple ongoing projects such as the Hongqi Rapid Road East Section, Tashan North Road tunnels, and the Port City West Street interchange, with a focus on completing key nodes by the end of the year [1][24]. - The Port City West Street interchange is a critical node in the "one horizontal and two vertical" rapid road project, designed as the largest and only three-layer interchange in Yantai [4][6]. Group 2: Construction Progress - The Port City West Street interchange features a total length of 1.3 kilometers for the north-south main line and 2.1 kilometers for the east-west main line, with 24-hour construction to ensure completion by the end of September [6][4]. - The construction of the Guanhai Road sunken interchange aims to alleviate traffic congestion, with completion expected by the end of October [11][7]. - The Tashan North Road tunnel project is progressing well, with the eastern section's excavation completed by 88% and the entire project expected to be completed by the end of 2026 [19][20]. Group 3: Future Implications - The rapid road network is expected to relieve congestion, enhance travel quality, and promote cross-regional integration, supporting Yantai's development as an important gateway to Northeast Asia [24][1]. - The comprehensive transportation system planning aims for residents to access rapid roads within 10 minutes, highways within 20 minutes, and external hubs within 30 minutes, significantly improving urban mobility [1][24].

近日,由中铁建工集团承建的烟台城市快速路项目施工现场呈现一派繁忙景象。作为烟台市重点民生工 程,该项目宫家岛立交段和红旗路主线已进入全面施工阶段,300余名建设者放弃"五一"节假日休息,全力 冲刺工程节点。 在宫家岛立交段施工现场,桥梁上部结构施工正有序推进。项目负责人介绍,该工程整体造价约11.31亿元, 项目整体征拆、管迁量大,部分施工区域位于现状高速、主干路,车流量大,不允许封闭交通,交通导行难度 较大。为克服以上难点,项目部施工过程中,应用BIM技术优化全过程管理,建立多部门协同机制,动态跟踪 征拆管迁进度,保障资源配置与工序衔接,同时,对高速及主干路区域采用"分幅分段+错峰导行"方案,引入 智能交通监测系统实时调整导行路线,最大限度减少对交通影响,关键工序均安排在夜间低峰时段进行,并 设置装配式围挡及警示设施降低通行干扰。 中铁建工集团烟台城市快速路项目经理孙其文称,针对大跨度钢梁施工,采用工厂预制与现场精准定位相 结合的工艺,运用全站仪激光定位提升安装精度,结合有限元模拟优化吊装时序,同步实施动态应力监测确 保结构安全；针对悬挑式盖梁,研发模块化可调支架体系,采用自动化张拉设备精准控制预应力,结合 ...
