History

Exit B of Workers' Stadium station, Line 3.

Line 3's route has undergone substantial changes on the planners' drawing board. In the late 1990s, one draft of the subway plan showed Line 3 running from Xiaomeichang to Cuigezhuang. Half of that route was then folded into Line 6.^[10][11] In 2010 and 2011, Line 3 was mentioned in the development plans of other subway lines.^[12]

By January 2012, the Line 3's western section was slated to run east from Tiancun station in Haidian District under Fushi Road to Fuchengmen station.^[13] On March 15, 2012, Line 3 was reportedly planned to run from Tiancun station to the eastern suburbs of Beijing in Gaoxinzhuang and Pingfang and to be built by 2020.^[14]

In June 2012, Beijing media reported the station plan of Line 3.^[15]

In January 2013, subway planners were examining whether to extend the Line 3 through the city centre given the concentration of historic relics in the area.^[16][17] In January 2014, it was reported that Line 3 will have 27 stations, with up to 16 transfer stations, including Ganjiakou station on Line 16 and Zhangzizhonglu on Line 5.^[18] The station plan for Ganjiakou had been released in 2013 by Beijing Municipal Commission of Urban Planning, which depicted the Line 3 platform built over that of Line 16.^[19] In February 2014, an official was quoted as saying that "Line 3 would run along Di'anmen Street, not Jingshan Front Street, with paralleling from Ping'anli to Nanluoguxiang."^[20][17]

On September 14, 2015, Line 3 (from Tiancun to Caogezhuangbei) was approved by NDRC. It will be 37.4 km in length with 27 stations.^[21][22] On April 19, 2016, the first phase of Line 3 started construction.^[23]

On May 1, 2024, the Beijing Municipal Commission of Planning and Natural Resources adopted station names of line 3 phase 1.^[24] On June 15, 2024, test run of line 3 has started.^[25]

On September 29, 2024, Beijing Infrastructure Investment (BII) company announced the planning scheme of line 3 eastern extension, a 6.4 km underground section with 5 new stations, but of which the potential termini Caogezhuangbei will only have reservation places for future plans. Once eastern extension completed, it will connect with line 20 (R4) at Guanzhuangluxikou, and line M101 at Gaoxinzhuang.^[26]
