Jakarta MRT Phase 2A Construction Update: Challenges and Progress
Complex Engineering in Jakarta's Infrastructure Development
PT MRT Jakarta continues to advance the construction of MRT Phase 2A CP202, connecting Harmoni to Mangga Besar. As of November 25, 2025, the project has achieved 60.2% completion, according to Sony Desta, Division Head of Project Management for Construction (PMC) 1 MRT Jakarta. The construction, which started in 2022, has been ongoing for three years and is expected to be operational by 2029.
Technical Challenges and Innovative Solutions
The CP202 section, spanning 1.8 kilometers, presents significant engineering challenges. Unlike previous MRT tunnels that were constructed in parallel, this section features a stacked tunnel design. This complex configuration requires sophisticated engineering solutions and has led to the construction of stations with four underground levels, reaching depths of up to 28 meters.
Project Scope and Future Implications
The MRT Phase 2A project is divided into three main packages: CP201 (Bundaran HI to Monas), CP202 (Harmoni to Sawah Besar), and CP203 (Glodok to Kota). The successful completion of CP202 will be crucial for the overall Phase 2A development. When fully operational, this phase will significantly enhance Jakarta's public transportation system, reducing congestion and improving connectivity across the city.
