In the 1980s, under the government's resettlement plan, the residents of Hong Kah Village and Kampong Ulu Jurong were relocated to nearby towns newly built by the government, particularly into the present
Jurong Green,
Jurong Spring, and
Bukit Batok areas. Schools were shifted elsewhere, and one example is
Xingnan Primary School, which used to operate at a temple along "Hong Kah Road" in the village. The HDB estates of
Jurong Green and
Jurong Spring are given the name "Hong Kah," probably meaning that most of the villagers resettled there. When the village was cleared, the
PIE and
KJE projects started in the area, leading to the creation of "Jurong West Avenue 2," which brought about the rise of both
Jurong West New Town and
Choa Chu Kang New Town. The western part became inaccessible to the public first in 1996 and was used by the military for training activities (which is west of Jurong Road Track 22), followed by the eastern part of Hong Kah (which is east of Jurong Road Track 22) in 2005. In the past, there were several village roads that used to serve the area. Roads such as Hong Kah Road/Lane/Drive/Circle, Sing Nan Road, Kian Hong Road, Jalan Keladan, Jalan Beka, Jalan Pelawan, Jalan Jelawi, Jalan Sena, Lorong Putek, Jalan Buey, Jalan Mandar, and Jalan Ara. The last few roads, such as Jalan Lam Sam and Jalan Chichau, existed until January 2019. Jurong Road closed on 27 September 2020, and a reservoir will be built in its place in the future. In late 2018, massive construction works for the HDB estates started in Tengah C1 and C2 planning areas, which are estimated to be completed by 2025. Most of the construction work will be headed by China Construction (South Pacific) Pte Ltd, whereas a few other local construction firms will also be in charge of construction work. The HDB flats in Tengah are constructed via precast components. The first flats in Tengah were completed in 2023, and Tengah first opened to the public in September 2023. The neighbourhood centre, Plantation Plaza, opened on 28 June 2024. ==Town design==
