The Kranji Expressway (abbreviation: KJE) in Singapore connects from the BKE in Bukit Panjang and travels south-west to join with the PIE in Jurong West.

It passes through the housing estates in Jurong, Choa Chu Kang and Bukit Panjang, ending near the subzone of Kranji.

One of the most difficult jobs in laying the expressway was the clearing of large granite for which 300 kg of explosives were used.

The entire network of linking roads came about by the construction of a highway connecting PIE at Hong Kah and BKE at Zhenghua.

It was inaugurated on 4 March 1995 by Lim Hng Kiang.
