On 9 May 2018, the Land Transport Authority (LTA) announced Bahar Junction station as part of the proposed 24-kilometre (15 mi) Jurong Region line (JRL).

[2][3][4] The contract for the design and construction of Bahar Junction station and the adjacent Jurong West station was awarded to China Railway 11 Bureau Group (Singapore Branch) in December 2019.

[6] However, the restrictions on construction due to the COVID-19 pandemic has led to delays, with the completion date pushed to 2027.

[5][10] Hence, commuters from the Nanyang Technological University (NTU) on the Peng Kang Hill branch have to alight at this station to transfer for services towards Boon Lay.

With the need for a transfer, however, plenty of NTU students have commented they would prefer taking a direct bus route instead of taking the JRL when travelling between the school and Boon Lay.
