The Ministry of Transport plans to develop 16 new metro line projects in Ho Chi Minh City and Hanoi. In Ho Chi Minh City, eight new metro lines with a total length of 173 km have been planned by 2035. Most of these routes will run underground in the central districts. Further, the ministry has proposed developing three tramways and a monorail line spanning a length of 57 km. Hanoi is also expected to have eight metro lines with a total length of 305 km. These routes will be expanded to connect with satellite urban areas. In addition, tramways will be constructed to connect to urban railways.
