Construction began on 6 January 1987 and trackwork was completed on October 1989.
The station opened on 6 July 1990 as the western terminus of the East West line, and was the last station to be opened on the original MRT network.
Initially, the station had the station code 'W12', which was later changed to 'EW27' on 31 July 2001 when the MRT network map was revamped by the then Minister for Communications and Information Technology, Mr Yeo Cheow Tong.
The original name was "Jurong West" before the construction began and was renamed to Boon Lay.

As Boon Lay and Jurong West Neighbourhoods 7 and 8 were developed later, the station had deferred their need to construct the station until 6 January 1987.
The last MRT viaduct to be constructed was from Lakeside to Boon Lay on 11 August 1989.
