Core Points - The Beijing Infrastructure Investment Company has announced the environmental impact report for the connection project between the Yizhuang Line and Lines 5 and 10, which is set to commence construction by the end of this year [2][5] - The project aims to directly connect the Yizhuang Line with Line 5 and facilitate transfers with Line 10, significantly improving transit efficiency and service levels [3][4] Project Details - The connection project will span approximately 2.7 kilometers, with 2.2 kilometers of new underground construction and 0.5 kilometers utilizing existing lines, all of which will be underground [2] - The construction methods will include shield tunneling, open-cut, and deep excavation, with no blasting operations involved [2] - The project will utilize B-type trains with a six-car configuration to maintain consistency with the existing lines [2] Expected Benefits - The project is expected to reduce the transfer passenger flow at Songjiazhuang Station by approximately 10,000 during peak hours, alleviating congestion [4] - An estimated 71,000 daily passengers will benefit from the direct connection, with 36,000 changing to same-platform transfers, reducing transfer distances by about 150 meters [4] - Overall, over 170,000 daily passengers will benefit from the project, accounting for approximately 88% of the total average daily transfer volume at the station [4] Timeline - The project is scheduled to be completed and operational by December 2028 [5]

在北京轨道交通三期建设规划的各条线路中，亦庄线至5号线、10号线联络线虽然开启动作较晚，但进 展速度却很快。 近日，市发改委批复了亦庄线至5号线、10号线联络线工程项目的可行性研究报告，可研的批复是一项 工程开工前重要的环节，意味着这条线路距离开工已经不远了。 同时，京投公司官网今天也公示了亦庄线至5号线、10号线联络线工程的环评报告全文，其中表示，该 工程初步计划今年年底开工，2028年12月建成。 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。 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。 环评报告估算，在亦庄线和5号线贯通运营后，每天宋家庄站约7.1万人次可以不用再换乘。 而且由于10号线西向东方向与亦庄线、5号线贯通线的南向北方向是同台换乘的，因此3.6万人次将从原 来要步行150米换乘，改为了更便捷的同台换乘。整个宋家庄站日均将有17.1万人次的乘客因此受益， 占宋家庄站日均换乘总量约 ...
