 The expressway is being built in three phases.Phase 1 from Bukit Tiu to Kuala Krai was constructed first, as the section runs along the state-owned land, eliminating the compensation costs for land takeovers.Meanwhile, Phase 3 from Pasir Hor to Kota Bharu will be the final section to be built, as the section will be an elevated expressway built on top of the existing Federal Route 8, making the section as the most expensive section of the expressway.
