Tengah, Singapore

In the old maps, the area appears as Tengeh or Tengah. In Malay, the word Tengah means "centre", "central" or "middle". The name may be taken from the nearby Sungei Tengah (Malay for Tengah River).

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" at 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" that 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 till January 2019. Jurong Road closed on 27 September 2020 and is being replaced by Tengah Way and Tengah Drive.

In 2018, massive construction works for the HDB estates started in Tengah C1 & C2 planning areas, which is estimated to be completed by 2025. Most of the construction works will be headed by China Construction (South Pacific) Pte Ltd whereas few other local construction firms will also be in charge of construction works. The HDB flats in Tengah are constructed via precast components. The first precinct of flats were completed in 2023 and the neighbourhood centre which would be linked to West Edge @ Bukit Batok via an overhead pedestrian bridge will be completed by the mid-2020s.

This area will be connected to the Jurong Region MRT line in 2027, with MRT stations Tengah, Tengah Plantation and Tengah Park servicing the area, and a new integrated transport hub to be ready by 2027.[4]

The bigger part of the former Hong Kah Village was an SAF military training area until 10 November 2015. The military training around the area was gradually shifted to Ama Keng Road and training for Keat Hong Camp were now trained at Ama Keng. Massive construction and earthworks subsequently began in October 2015.
