When the project received approval in 2012, its estimated cost stood at Tk 219.85 billion (21.985 crore). The total project cost has since increased to Tk 334.72 billion (33.472 crore).
Bangladesh has secured a loan of Tk 197.18 billion (19.718 crore) from the Japan International Cooperation Agency (JICA) to finance the project.
According to DMTCL sources, the authorities also plan to extend the metro rail from Uttara to Tongi in the future.
This extension would add approximately 7.5 kilometres to the line and include five new stations. However, the government has not yet approved a project for this extension.
The government plans to construct six metro rail lines across Dhaka with a combined length of approximately 140 kilometres. The network will integrate the individual lines into a comprehensive metro rail system.
Construction is already under way on two additional metro rail projects: one connecting Kamalapur with Hazrat Shahjalal International Airport, and another running from Savar to Bhatara via Gabtoli, Mirpur and Gulshan.
The government has also approved a project to construct another metro rail line from Gabtoli to Dasherkandi via Mohammadpur and Karwan Bazar.
In addition, the current BNP government plans to integrate several monorail routes with the metro rail network.
