北京轨道交通三期建设规划中的各条线路，进度在明显加快。 上月25日我们刚推送了亦庄线至5号线、10号线联络线第一次环评公示的消息，今天，京投公司官网就开始公示这条新线的第二次环评。 第二次环评中，这条线路的具体走向有了详细的公布。而且环评报告中还给出了开工和开通时间。计划今年底开工建设，2028年建成通车。 当然，最终的具体开工、开通时间以相关部门正式发布为准。 1 亦庄线目前是在宋家庄站与5号线、10号线三线换乘，因此宋家庄站也是北京轨道交通路网中换乘量最大的车站之一。 环评报告中表示，该工程计划今年底开工建设，计划于2028年6月建成通车，具体开工、开通时间以市政府有关部门发布为准。 今年年初发布的北京轨道交通年度建设计划中，今年计划新开工的线路中并没有包括亦庄线至5号线、10号线联络线，如果这条线路最终能实 现年底开工，就意味着是开工提前的惊喜，无疑对于沿线居民来说是个好消息。 但如果乘坐亦庄线想继续向北，那就要从亦庄线下车，换乘5号线。如果想去国贸、西三环等地，则要下车换乘10号线。这多少都会给乘客带 来不便。 而亦庄线至5号线、10号线联络线工程要解决的就是这个问题。 此前，在轨道交通三期建设规划中 ...

7月15日，北京市基础设施投资有限公司发布北京轨道交通亦庄线至5号线、10号线联络线工程环境影响评价第二 次公示。此次公示对工程的具体走向进行了更详细的披露，提到该工程计划今年年底开工，2028年6月建成通车， 具体开工、开通时间以市政府有关部门发布为准。 未来将实现亦庄线与5号线、10号线贯通运营 既有亦庄线与5号线贯通运营，与10号线上行方向同台换乘 这项联络线工程的建设，就是为了让亦庄与中心城区的交通联络更紧密，加强亦庄地区与中心城区的产业联动， 打通线网断点，提升线网直达性，缓解宋家庄站换乘压力。 二次环评披露的信息显示，北京轨道交通亦庄线至5号线、10号线联络线工程南起现状肖村站，北至现状宋家庄 站，全长约2.7公里，其中新建线路约2.2公里，利用既有线路0.5公里，均为地下线。无新建、改（扩）建场站， 但是线路会预留郭家庄路地下车站一座。 北京轨道交通亦庄线至5号线、10号线联络线工程示意图。图片来自北京市基础设施投资有限公司官网 此次环评公示中没有具体提及预留郭家庄站的位置信息，不过郭家庄路是一条东西向道路，其位置就在地铁10号 线的成寿寺站与地铁亦庄线的肖村站之间，预留车站也是为了后期的其他工 ...

Core Viewpoint - The construction of the Yizhuang Line to connect with Line 5 and Line 10 is a significant development for residents in the southern region of Beijing, enhancing convenience and reducing transfer inconveniences at major interchange stations like Songjiazhuang [1][4]. Group 1: Project Overview - The Yizhuang Line to Line 5 and Line 10 connection project has begun its first environmental impact assessment (EIA) public announcement, indicating progress in the planning phase [1]. - The project will span approximately 2.7 kilometers, starting from the existing Xiaocun Station to Songjiazhuang Station [4]. - The initial EIA does not provide detailed route plans or diagrams, leaving the final route configuration uncertain until the second EIA [4]. Group 2: Operational Improvements - The project aims to facilitate through operation between the Yizhuang Line and Line 5, while optimizing transfers with Line 10, thereby improving overall passenger experience [5]. - The integration will occur in two phases: the first phase will align the signaling systems of the Yizhuang Line and Line 5, allowing for flexible train operations during peak hours to alleviate congestion at Songjiazhuang Station [5]. - The second phase will implement through operation with Line 10 once its equipment reaches the end of its service life, further enhancing connectivity [5].

Core Points - The Beijing Infrastructure Investment Company has announced the environmental impact assessment for the connection line project between the Yizhuang Line and Lines 5 and 10, which is approximately 2.7 kilometers long and aims to improve transportation connectivity between Yizhuang and the central urban area [1][2] - The Yizhuang Line currently experiences significant passenger flow, with nearly 200,000 daily riders, leading to congestion at transfer points, particularly at Songjiazhuang Station [1][2] - The project aims to facilitate direct operation between the Yizhuang Line and Line 5, as well as optimize transfers with Line 10, enhancing the commuting experience for passengers [2][3] Project Details - The connection line will run from the existing Xiaocun Station to Songjiazhuang Station, utilizing both new underground sections and existing lines to achieve operational connectivity [2] - The project is part of a broader plan to improve urban rail transit, with previous documents indicating a future goal of full operational integration among the Yizhuang Line, Line 5, and Line 10 [2] - Future steps will include line optimization and equipment upgrades to enable seamless operation between the Yizhuang Line and Line 10 [2][3]
