Thomson–East Coast Line On 29 August 2012, the station was first announced as Sin Ming station as part of the 22-station
Thomson Line (TSL). In February 2014, the contract for the station's construction was awarded to
Penta-Ocean Construction Co. Ltd. The S$454 million (US$ million) contract included building the associated tunnels. The station's construction began in 2014, with a scheduled completion date of 2020. On 15 August 2014, the
Land Transport Authority (LTA) announced that the TSL would merge with the Eastern Region Line to form the Thomson–East Coast Line (TEL). Bright Hill station, along the proposed line, would be constructed as part of TEL 2, consisting of six stations between
Springleaf and
Caldecott. To install the
bored piles that would be part of the earth-retaining stabilising structure, specialised machinery was used due to the hard granite rocks at the site. The structure was needed for soil retention and to facilitate underground excavation works. The roads above the station needed to be diverted several times. Barriers were installed to minimise noise pollution, and workers draped noise curtains on heavy machinery. For the soft soil and loose sand at the ground underneath Inglewood Estate and
Kallang River, soil strengthening works took place before the tunnels were bored. With restrictions imposed on construction due to the
COVID-19 pandemic, the TEL 2 completion date was pushed to 2021. On 14 December 2020, it was further announced that the opening of TEL 2 was delayed to the third quarter of 2021 so the rail system software for the line could be reviewed. As announced during a visit by Transport Minister
S. Iswaran at Caldecott station on 30 June 2021, the station began operations on 28 August 2021.
Cross Island Line On 25 January 2019, the LTA announced that Bright Hill station would be an interchange with the proposed
Cross Island Line (CRL). The station will be constructed as the terminus of Phase 1 (CRL1), which will contain 12 stations and operate to
Aviation Park. CRL1 was expected to be completed in 2029. However, the restrictions imposed on construction works due to the COVID-19 pandemic led to delays and the CRL1 completion date was pushed by one year to 2030. The contract for the design and construction of the CRL station and associated tunnels was awarded to Penta-Ocean Construction Co. Ltd. at S$526 million (US$ million) on 30 March 2022. Concurrent with construction works, Sin Ming Avenue will be pedestrianised to establish a Transit Priority Corridor along the road, which will include new cycling paths and bus lanes. Construction is scheduled to start in the second quarter of 2022, with an expected completion date of 2030. ==Station details==
