History Line 5 was originally built under the direction of Minhang District and remains the only line in Shanghai Metro system that was originally built under the supervision of a county-level government. In 1998, Minhang District authorities signed a contract with Shanghai Jiushi Group to build the line. In 2000, Shanghai Jiushi Group signed a contract between Alstom to purchase trains and started its construction. In 2002, Shanghai Modern Rail Transit Incorporated, a subsidiary of former , was given management of the line. The line entered passenger operations on 25 November 2003, on an initial segment between and stations, entirely within Minhang District. Prior to integration with the rest of the Shanghai Metro network, it used its own ticketing system. In 2005, it was integrated with Shanghai Metro's ticketing system, which enabled an in-station interchange to line 1 at Xinzhuang station. At the same time, management and operation of the line was taken over by Shanghai No. 1 Metro Operation Co. Ltd. Phase II extension and renovation Phase two of the line, which would extend the line further south into Fengxian District, began construction on 30 July 2014.
