Bukit Panjang is a suburban area situated in the Central North-Western part of Singapore. The Bukit Panjang Planning Area, located in the West Region, encompasses the Housing Development Board's housing estate of Bukit Panjang New Town and the Bukit Timah Nature Reserve.
Bukit Panjang was originally named Zhenghua, and advanced earthworks begun on 15 June 1981. HDB flats rose up the spring on 20 May 1985, and so far only Blocks 1xx and 2xx were built. Neighbourhood 4 was up and running by 1989, and followed by Neighbourhood 5 and 6 which was the recent ones since 1995.
Bukit in the Malay Language means "hill" and Panjang means "long". Bukit Panjang literally means "long hill" which gets its name from the long range of high hills which ends in Bukit Timah to the south.
At the height of the movement to change place names in Singapore to Mandarin ones using hanyu pinyin romanization, the new town to be built in the area was initially known as Zhenghua (正华), along with Yishun (义顺) for Nee Soon, and Zhujiao market for tek kha (竹脚) market in Kandang Kerbau. The trading of old dialect names which have gained common currency for unfamiliar, Mandarin ones was not well received by the public, and Bukit Panjang was quickly reinstated. However, the name Zhenghua is preserved in the name of the flyover between Bukit Panjang Road and the Bukit Timah Expressway as well as the Zhenghua Park.
The Bukit Panjang area comes under the administrative lead of the Holland-Bukit Panjang Town Council, which oversees the management and maintenance of the many apartments (HDB Flats) and commercial units in Bukit Panjang.
