The VND65.40 trillion (USD2.70 billion) project, the fifth of its kind in the capital, would run 38.43km, with a 6.5km underground section and 2km of elevated lines. It would have 21 stations with six underground.
The project, which is scheduled to be put into operation in 2026, would link passengers from the outlying Thach That District to the city centre and reduce urban traffic density.
Capital sources for the metro line would be sourced from the city budget. Investment for the entire route would be raised in just one phase.
