The country’s first underground metro rail will be running at a depth of 10 to 30 metres below the ground along most of the 19.87-kilometre route from Dhaka Airport to Kamalapur.

Civil works of the country’s first underground metro rail will start in December this year, after a two-year delay.

Construction of the country's first underground railway may start in July with funds from Japan. Named MRT Line-1, this track will link the capital's airport and Kamalapur. It will also have an elevated part to connect Purbachal with Notun Bazar. The project deadline is 2026.
