In 2001, there were major changes in the political constituencies of Jurong. Boon Lay Constituency, together with Teban Gardens and Pioneer, were absorbed into the expanded West Coast GRC. Hong Kah Constituency was re-designed to include towns of Chua Chu Kang (Limbang and Yew Tee) and Bukit Gombak and only Nanyang and Gek Poh remained in the constituency, this time including the N9 region of Nanyang. Jurong Constituency was abolished. Hong Kah and Bukit Batok were regrouped into the newly created Jurong GRC, along with Yuhua and Taman Jurong. As such, the entire political system of Jurong was changed with 3 GRCs as a result.
