It was formerly from part of Bedok, Changi & Kampong Chai Chee constituencies prior to the 1984 general election as the population in Bedok grew and absorbed into the then greater three-member ward Bedok Group Representation Constituency before 1991 general election and Bedok GRC had become a four-member ward. It was reformed just before the 2015 general election after being carved out from East Coast GRC.
In the 2020 general election, it will be absorbed back into East Coast GRC.
