The Kranji Expressway (KJE) links the Bukit Timah Expressway (BKE) and the Pan-Island Expressway (PIE), at the Tengah flyover, near Hong Kah.
Construction of the expressway started in 1990 and was completed in 1994.
Kranji Expressway (KPE) runs a total length of 8.4km. It is one of the first few roads of Singapore to feature a new anti-skid surfacing.
The KJE passes through the Kranji estate in Woodlands, connecting it to Jurong, Choa Chu Kang and Bukit Panjang. As it connects Jurong to Woodlands, the expressway is a faster alternative to Malaysians who travel from Johor to Singapore via the Woodlands Checkpoint.
