Through the Jurong East Modification Project, an additional track and platform were built in 2011 to improve train frequencies on the NSL.

In May 2018, it was announced that the station would be an interchange with the Jurong Region Line (JRL) when the second stage opens in 2028.

[2][15] As announced by MRT Corporation chairman Michael Fam on 10 March 1988,[16] Jurong East station opened on 5 November that year.

[23][24] In July 2008, the Land Transport Authority (LTA) announced the Jurong East Modification Project (JEMP), which involved the construction of a new platform and tracks to increase train frequency for the NSL.

[43][44] Another set of noise barriers from Boon Lay Way to Jurong East Avenue 1 were installed from 2018 to 2020.

[48][49] The exercise saw the first deployment of the Human Security Radar – a fully automatic walk-through system with the ability to screen through a crowd for suspicious items.

[51][52][53] While the Jurong Region Line (JRL) was first announced on 23 October 2001,[54][55] the project was put on hold.

[57] On 9 May 2018, the LTA announced that Jurong East station would interchange with the proposed 24-kilometre (15 mi) JRL.

[59][60] However, the restrictions on construction due to the COVID-19 pandemic have led to delays, with the completion date pushed to 2028.

A sheltered pedestrian bridge was built to connect the MRT station to the temporary bus interchange, which was to operate until the completion of the Jurong East Integrated Transport Hub in 2027.

The escalator and staircase leading to the Hub Plaza were closed on 18 December 2022 with new temporary linkways constructed to connect to Exit A of the station.

[65] Jurong East station was designed by Scott Danielson of Parsons Brinckerhoff,[85] who took inspiration from the adjacent Jurong East Bus Interchange and designed the space-frame roof of the station – a geometric pattern of cylindrical steel tubes connected by ball joints and topped with a flat lid.

[88][89][90] When the Jurong East Integrated Transport Hub designed by Aedas is completed,[91] a 90 m (300 ft) link bridge over the tracks will connect the two buildings flanking the station.

[93][94][95] As part of SMRT's heritage-themed artwork showcase Comic Connect, the station features A Journey Through Jurong East by students from the School of the Arts.
