Line 22 (Shanghai Metro, 2017 scheme)

Line 22, as part of the Shanghai Metro system, refers to a proposed extension of the existing railway network under a scheme developed around 2017. This designation typically signifies a planned subway or light rail line intended to expand connectivity within Shanghai and/or to surrounding areas. Details such as the specific route, stations, projected opening date, and operational characteristics would have been defined in planning documents associated with the 2017 scheme. The line may connect existing metro lines, serve new residential or commercial areas, or improve transport links to suburban districts. It is important to note that proposed lines are subject to revisions, delays, or even cancellation depending on funding, feasibility studies, and evolving urban planning priorities. To determine the current status and details of this specific proposal, one would need to consult official Shanghai Metro planning documents or announcements from the relevant transport authorities.
