1月19日上午10点，通城高架路（萧绍路—南秀路）段正式通车，显著提升杭州南站与萧山机场两 大交通枢纽间的联络效率，这也标志着杭州快速路总里程突破520公里，城市内部通行与对外枢纽衔接 能力再上新台阶。 通城高架路是杭州"两环五纵八横八连"快速路网格局中"一纵"的组成部分，也是"东湖—九堡—通 城"南北向高架快速路体系的南段组成部分，全长约11.7公里，采用"高架快速通道+地面道路"的立体布 局，串联起新塘街道、宁围街道、新街街道和萧山经济技术开发区，也是杭州南站交通枢纽的关键配套 工程。 此次建成通车的萧绍路至南秀路段长2.5公里，属于通城大道快速路三期工程（萧绍路—晨晖路） 的重要部分。三期工程北起萧绍路，南至晨晖路，主线高架全长3.23公里，双向6车道设计，主线时速 可达80公里，同时配套地面辅道满足日常通行需求。 值得一提的是，项目在推进中大胆探索技术创新，采用"复合结构桥墩"工艺，即每个桥墩的立柱通 过104根主筋，与钢盖梁的底板、顶板精准对接，再用螺母在钢盖梁顶板紧固，实现两者无缝拼接。此 项工艺在国内市政工程领域应用尚属首例，正被转化为行业"团体标准"，为国内同类工程提供可借鉴 的"杭州经验"。 ...

Core Viewpoint - Qingdao has significantly improved its urban road network through city renewal initiatives, focusing on enhancing connectivity and traffic efficiency, which supports economic and social development [2][3][4]. Group 1: Urban Road Network Development - Since the beginning of the 14th Five-Year Plan, Qingdao has concentrated on four key areas: rapid network formation, three-dimensional nodes, main road improvements, and secondary road connectivity [2]. - The completion rate of the rapid road network in the eastern urban area has increased from 47.3% to 73.6%, indicating a well-structured "four vertical and five horizontal" rapid road system [2]. - Major rapid road projects, including the Chongqing Elevated Road, have been completed, significantly reducing travel times across the city [3]. Group 2: Key Infrastructure Projects - The Liyang Road Rapid Road integrates multiple transportation modes, enhancing connectivity and reducing travel time from 40 minutes to approximately 15 minutes during non-peak hours [2]. - The Chongqing Elevated Road has reduced peak travel time from 50 minutes to under 20 minutes, greatly improving north-south connectivity in the city [3]. - Over 20 major arterial roads have been constructed, expanding the road network and alleviating traffic congestion in critical areas [4]. Group 3: Traffic Management and Efficiency - The construction of key interchanges, such as the Jinjialing Interchange, has improved the road network's capacity and traffic flow, addressing congestion at major junctions [4][5]. - The city has successfully completed the opening of 124 previously unconnected roads, enhancing the overall efficiency of the road network and improving citizens' travel experiences [5].

齐鲁晚报·齐鲁壹点记者 王瑞超 实习生 李文慧 通讯员 郭小宁 宋磊 赵苑 8月15日，烟台迄今规模最大的三层互通立交——港城西大街互通立交建成通车。该工程由中铁十局承建，它的建 成标志着烟台快速路网建设取得重大突破。 港城西大街互通立交整体为苜蓿形设计，南北主线长1.3公里，东西主线长2.1公里，共设8条转向匝道及2条集散车 道。其中4条匝道实现德润快速路与港城西大街的交通转换，东西主桥无缝衔接港城西大街，北侧主桥直通德润快 速路。 该工程于2022年10月1日破土动工，道路建设期间，中铁十局建设团队克服钢箱梁跨路施工安全压力大、吊装精度 高、交通流量大等困难，以及克服机电系统繁杂、调试技术难度突出等不利因素，优化施工方案，采用BIM+技 术，加强资源配置，加大施工力量投入，确保工程提前完工。 作为烟台市快速路网"两纵一横"战略布局中的"纵横"连接枢纽，港城西大街互通立交的建成通车将显著提升路网 通行效率，支撑国土空间优化调整，为构建"安全可靠、舒适便捷、集约高效、绿色生态"的现代化综合交通体系 注入强劲动能。 ...
