en.Wedoany.com Reported - Multiple metro lines under construction in Qingdao have recently seen intensive updates on project progress. Line 2 Phase II recently achieved a successful one-time power transmission across all substations along the line. After the final section of high-voltage busbar at the Expo Garden Station was successfully energized, all equipment has been operating smoothly, and the core energy hub has been officially put into use. On May 25, the construction of the auxiliary B2 entrance at Hanchuan Road Station commenced with the launch of the city's first large-diameter circular pipe jacking machine, accelerating the overall construction of the line. The line is approximately 8.9 kilometers long, with 8 stations and 10 sections, starting from Licun Park Station and ending at Expo Garden Station. Among them, Xiawangbu Station will allow transfers to Line 15, and Expo Garden Station will connect with the existing Line 11. The line is scheduled to open to traffic by the end of 2026.

Qingdao Metro Line 5 has achieved multiple milestones in shield tunneling and prefabricated construction. Recently, the section between Hefei Road and Jinsongqi Road Station completed the city's first shield dismantling operation in a cavern without disassembly. The structural construction of auxiliary entrances E and F2 at Ningxia Road Station has been fully completed, marking the final phase of the station's entrance works. At Funing Overpass Station, a 98-meter prefabricated platform slab was completed in just 15 days, from factory prefabrication to tunnel assembly, making it the first station on Line 5 to adopt prefabricated internal structure platform slabs. Located in Qingdao's core urban area, Line 5 starts from Maidao Station and ends at Yunling Road Station, forming a "C" shape covering the three districts of Shinan, Shibei, and Laoshan. It includes 27 stations (12 of which are transfer stations) and connects with 8 metro lines, with a planned opening to traffic in 2028.

Qingdao Metro Line 7 Phase II has achieved a breakthrough on the left line between Dongguozhuang Station and Zhoucun Station. Line 7 Phase II consists of a northern section and a southern section: the northern section is approximately 13.1 kilometers long, running north from Dongguozhuang Station to Yingpu Road Station, with 11 stations (Zhoucun Station, Qiandongcheng Station, Dongcheng Station, Jingdai Station, Huanxiu Station, Wenfeng Road Station, Lan'ao Road Station, Heshan Road Station, Qingwei Road Station, Bei'an Station, and Yingpu Road Station); the southern section is approximately 3.8 kilometers long, running south from Xingguo Road Station to Cangkou Station, with 3 stations (Cangkou Station, Zhenhua Road Station, and Wen'an Road Station). The line mainly passes through the central area of Jimo and western Licang, providing a rapid connection between Jimo, Chengyang, and the eastern main urban area. It is expected to open by the end of 2027.
