Shenzhen Metro Line 3 (formerly branded as Longgang line), runs northeastward from Futian Bonded Area to Pingdi Liulian. Line 3 opened on 28 December 2010. Line 3's color is blue.^[2]

Since opening, it has been heavily trafficked and became a major transport option for urban workers. Line 3 currently has a service interval of 5 minutes between trains across the entire length of the line. Sectional trains operate on weekdays, between Huaxin and Tangkeng, from 7:15 am to 9:15 am and from 5:45 pm to 7:45 pm. This is to alleviate surges in passenger traffic at Buji, since the opening of the connecting Shenzhen East.^[3]

History

The first phase of Shenzhen Metro Line 3 started construction in July 2007. On 23 April 2008, the Shenzhen Municipal Planning Bureau renamed the still under construction Shenzhen Metro Line 3 to "Longgang Line". The renaming was later reverted in 2013.^[4]

First stage

The first phase of the line from Shuanglong to Caopu stations officially began operations on 28 December 2010. This section is almost entirely elevated except near Tangkeng. It starts from Longgang District and runs mainly along Shenhui Road, to Luohu District. The first phase has 16 stations, with a total length of 25.138 km (15.620 mi).

Second stage

The first phase (underground section) of the line from Caopu to Hongling stations and the second phase of the line from Hongling to Yitian stations, opened on 28 June 2011.

Third stage

The third phase of the line from Futian Bonded Area to Yitian stations, opened on 28 October 2020.

Fourth stage

The fourth phase of the line from Shuanglong to Pingdi Liulian stations, opened on 28 December 2024.

Future development

Long term plans

Long term plans include extending Line 3 even further east into neighboring Huizhou City along with Line 14. On 7 August 2013 a "Memorandum of Cooperation" was signed to coordinate transport planning and urban development between the two cities, formalizing the planning process for the proposal.^[5]^[6]
