Lok Ma Chau Control Point was the third road crossing built between Hong Kong and China, after Man Kam To and Sha Tau Kok. 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 opened to traffic on 18 October 1991, adding two more lanes.
