The Indonesian Ministry of Transportation has announced the Construction of a 24.5-km mass rapid transit line connecting Tomang, West Jakarta, with Medan Satria, a district in Bekasi City, West Java - one of Jakarta's satellite cities.

This is the first phase of a project on building an 87-km line connecting Balaraja in Banten and Cikarang in West Java. The next phase is anticipated to begin in 2033. The new line will be built simultaneously with Phase 2A of the North-South MRT Line, which is expected to be completed in 2027. This is an extension to North Jakarta, from the Hotel Indonesia (HI) roundabout to Kota Tua, West Jakarta, which is now 40% complete. It is expected to be completed in 2031.

Previously, in 2019, Jakarta's first MRT line was put into operation, spanning 16 km long, connecting the Hotel Indonesia roundabout to Lebak Bulus (South Jakarta). The Jakarta MRT project will be further extended to South Tangerang, Banten, from Lebak Bulu's station, which is the main artery leading to the center of Jakarta. In May 2024, the Japan International Co-operation Agency (JICA) provided a loan of YEN 141 billion (US$ 998 million) for the project.
