The Hanoi Metropolitan Railway Management Board (MRB) has been assigned to prepare an investment plan for Metro Line No. 5, connecting inner and outer districts. The city’s planning and architecture departments will collaborate to develop a 1:500-scale design that integrates transit-oriented development (TOD) and ensures land availability for urban growth. The MRB must also align the project with Hanoi’s mid-term public investment strategy for 2021-2025.

The proposed 38.43 km metro line, with sections at elevated (2 km), underground (6.5 km), and ground level (29.93 km), will link Van Cao Street near West Lake to Hoa Lac satellite town, passing through key districts. The estimated cost is VND 65 trillion (USD2.5 billion), with train speeds reaching 120 km/h (90 km/h underground) and intervals of 3.3 minutes. The project aims to relieve congestion and reduce pollution, with construction expected to begin in 2025 following approval from the Hanoi People’s Committee.
