Jakarta’s next major Mass Rapid Transit (MRT) expansion — a 24.5 km east–west corridor — will cost around IDR50 trillion (USD3 billion), according to PT MRT Jakarta. The line will stretch from Medan Satria in East Jakarta to Tomang in West Jakarta, featuring 21 stations and a new train depot.
Construction is slated to begin in 2026, with land acquisition and utility relocation already underway. An international tender is expected in October or November 2025, with Japan-based financing secured and local partnership requirements for foreign bidders.
The operator is concurrently working on a northbound extension from the Hotel Indonesia Roundabout to Kota, now 50 per cent complete. The 6-km segment, estimated at IDR12 trillion (USD739 million), is expected to finish by 2029.
PT MRT Jakarta reports significant benefits from the existing MRT line, including a reduction in traffic congestion and environmental damage, with estimated savings of IDR4.1 trillion in avoided losses and travel time reductions.
