Lim Chu Kang was one of the locations where the Imperial Japanese Army first landed on the north-western coastline on 8 February 1942 during the Invasion of Singapore of the World War II, catching the defending 22nd Brigade Australian soldiers by surprise.

In 1980s, residents of the Ama Keng were resettled and all eventually moved out to Jurong West, Choa Chu Kang and Yew Tee.

After the last resident left, on 10 April 2002, the SAF took possession of the entire Ama Keng for military training use.

In the 1960s and 1970s, Ama Keng was well-served by shops, a police station as well as a maternity and child welfare centre.

Neo is credited with the development of the Lim Chu Kang area, where he built roads, houses and a seaport.

A small HDB estate which was opposite Lim Chu Kang Road was built in the early 1980s, but had been cleared by the late 1990s and expanded the Sungei Gedong Camp's military training area in 2000s.

On 18 July 1993, new service 175 was introduced from Lim Chu Kang to Upper Bukit Timah Road (Loop) replacing route 206 which was withdrawn.

[7] Today, Lim Chu Kang is still largely rural and is located in close proximity with the Western Water Catchment.

The 62 farms in the western part of Lim Chu Kang are being cleared progressively from April 2020 and completing in December 2022, to make way for military training areas.

It has also been an increasingly popular exploration for tourists in recent years, due in part to its close proximity to the Kranji MRT station.

The Ama Keng Chinese Temple (亞媽宮) in Lim Chu Kang was built in 1900 to worship Mazu, the holy mother, a goddess of peace and happiness.

[10] In 2002, the entire estate was sold back to the government in an en-bloc sale; its residents moved to newly built housing units in Jurong West.
