[The Beijing suburban railway will soon begin construction]The Second Public Notice on the Environmental Impact Assessment of the Northeast Ring Line of Beijing Suburban Railway from the southern entrance to Guanghua Section has been officially released. The feasibility study and preliminary design of the project have been completed, and it is planned to officially start construction and open in stages at the end of 2023. In the future, the Northeast Ring Line is expected to become the most obvious public transportation railway in Beijing, and it will reach the International Trade area in about half an hour from Huilongguan.
