History
Qingdao proposed a subway system in 1935, making it one of the first cities in China to propose a subway system. The proposed network was 42 km long and ran underground in the city center while elevated in the suburbs. However, the plan never gained traction due to turmoil from the Second Sino-Japanese War and Chinese Civil War. Planning resumed in 1989 only to be stopped again in 1995 after a national suspension of subway projects was declared due to worries of high costs and financial debts. Repeated attempts to gain approval for subway construction were unsuccessful until 2009 when it was finally approved by the NDRC and a test section of Line 3 started construction in July.
Another line, Line 1, is due to be completed in 2020. It will temporarily run along one of the sections of Line 7, from Xingguo Road station to Dongguozhuang station.
Line 4 has been under construction since 2016, and is due to be completed in 2022 from People's Hall station to Dahedong station. It will bring much convenience to Qingdao citizens once the line begins operation.
Line 6
Construction for Line 6 started at December 16, 2019. Line 6 is a 30 km line with 21 underground stations.
Line 8
The northern section will open in 2020, and the remaining section will open in 2021.
Line 2 (western extension)
A extension from Taishan Road to Lundu started construction on October 26, 2019.
Plans
According to the published plans, ultimately there will be 16 lines in total with a combined length of 836 km. All work is scheduled to be finished prior to 2050.
