History

Kajang Dispersal Link Expressway used to be called Jalan Kajang–Puchong (Jalan Sungai Chua on Kajang town side) 11 and Jalan Balakong 3211. The huge traffic jams that clogged traffic flow in Kajang town centre were the main reason behind the construction of the highway. Construction began in 2002. The expressway was completed in 2003 and began operation on 15 June 2004.[citation needed]
