亦庄线至5号线10号线将建联络线

Core Points - The Beijing Infrastructure Investment Company has released the full environmental impact report for the connection line project between the Yizhuang Line and Lines 5 and 10, which is set to begin construction by the end of 2025 [2][3] - The project aims to directly connect the Yizhuang Line with Line 5 and facilitate same-platform transfers with Line 10, significantly improving transit efficiency and service levels [2][3] - The construction will cover approximately 2.7 kilometers, with 2.2 kilometers being newly constructed underground lines, and is expected to alleviate congestion at Songjiazhuang Station, which currently handles the highest transfer volume in the network [2][3] Project Details - The connection line will start from Xiaocun Station in Chaoyang District and end at Songjiazhuang Station in Fengtai District, with no new or expanded stations planned [2] - The project will utilize shield tunneling, open-cut, and underground excavation methods, avoiding blasting operations [2] - The implementation of this project is part of the third phase of Beijing's urban rail transit construction plan, which aims to enhance connectivity for the Yizhuang New Town with the central urban area [3] Expected Benefits - The project is projected to reduce the transfer passenger flow at Songjiazhuang Station by approximately 10,000 during peak hours, benefiting over 170,000 passengers daily, which accounts for about 88% of the average daily transfer volume [3] - The estimated changes include 71,000 passengers no longer needing to transfer, 36,000 passengers switching to same-platform transfers, and 65,000 passengers adjusting their transfer platforms, thus shortening transfer distances by about 150 meters and 100 meters respectively [3] - The completion of the project is anticipated by December 2028, pending official announcements from relevant government departments [3]
