Lok Ma Chau Control Point  Lok Ma Chau Control Point () is an immigration control point in Lok Ma Chau, Yuen Long, New Territories, Hong Kong, which is on the border between Hong Kong and mainland China. It opened in 1989. It started providing 24-hour passenger clearance in January 2003, and is still the only Hong Kong control point with Shenzhen in mainland China to do so Its counterpart is the Huanggang Port in mainland China. Before reaching this point, vehicles must pass through police checkpoints along road to Lok Ma Chau Control Point. Permits must be carried in order to pass these points and to travel to the control points. Lok Ma Chau Control Point was the third road crossing built between Hong Kong and China, after Man Kam To and Shataukok. It was built as part of the New Territories Circular Road project, and was intended to relieve the congested Man Kam To Control Point. Construction began in December 1985. Customs, police, and other buildings were designed by the Architectural Services Department. The new crossing opened on 29 December 1989, initially only using the Eastern Bridge, providing two lanes. The Western Bridge was completed a few years later, adding two more lanes. In October 1993 Governor Chris Patten announced a plan to open the crossing on a 24-hour basis. This was strongly supported by the territory's business community, but criticised by villagers due to increased noise and dust pollution. Overnight border crossing was introduced on 4 November 1994 (i.e. after 3 November 1994). The control point began providing 24-hour passenger clearance from 27 January 2003 (i.e. after 26 January 2003). Construction of a new four-lane bridge, directly to the east of the existing two bridges, was proposed by the government in early 2003 to meet increasing traffic demand. Construction began in November 2003 and was completed in December 2004. The new bridge opened to traffic in January 2005. In 2015, Lok Ma Chau Control Point handled a total of 37 million people (including both drivers and passengers), making it the second-busiest road control point in Hong Kong, after Shenzhen Bay Control Point (which handled 41.5 million). For comparison, the nearby Lok Ma Chau Spur Line rail crossing handled 61.9 million. Cross border shuttle buses between Huanggang Port in Shenzhen and San Tin Public Transport Interchange (PTI) (less than 2 km from Lok Ma Chau Control Point), stop en route at Lok Ma Chau Control Point. These shuttle buses are scheduled to run at least every 15 minutes, 365 days per year.
