The Revised Strategic Transport Plan (RSTP) will include the construction of 5 Mass Rapid Transit (MRT) or metro rail lines in Dhaka to be implemented in three phases.
There is an excellent white paper (actually a detailed report) on this.
Line 6: The construction of Dhaka Mass Rapid Transit Development Project (DMRTDP) which includes the first metro rail line the MRT Line 6 from Uttara to Motijheel is expected to completed by 2019-2020 at the cost of Tk21,000 crore. The Line 6 is a north south line with a total length of 41 kilometre that will eventually connect Uttara to Ashulia and Motijheel to Kamalapur by 2025.
Line 1: The second line to be completed will be the MRT Line 1 also a north south line which will connect from Dhaka airport to Kamalapur at first and extended eventually connect Gazipur, Kamalapur to Keraniganj’s Jhilmil Residential Area and Khilkhet to Purbachal Residential Area. Japan International Cooperative Agency (JICA) has completed a pre-feasibility study which was accepted by Dhaka Transport Coordination Authority (DTCA). The report says the MRT will reduce the travel time to a mere 23 minutes from Dhaka airport to Kamalapur while going from Purbachal to Kamalapur will take just 39 minutes.
Line 5: The third metro rail line is a east west route the MRT Line 5 which will connect from Bulta to Badda with stops at Mirpur, Gabtoli bus terminal, Dhanmondi, Basundhara city mall and Hatirjheel link road at a total length of 35 kilometres. Jica’s feasibility study of the second and third metro rail MRT Line 1 project will be completed by 2016 and construction work will hopefully begin in 2017 and completed by 2025,” said Road Transport Highway Division secretary MAN Siddique.
Line 2: The fourth metro rail The MRT Line 2 will be constructed to connect Ashulia, Savar, Gabtoli, Dhaka University, DSCC Nagar Bhaban and Kamalapur at a length of 40 kilometres which will directly connect Dhaka EPZ to Kamalapur ICD.
Line 4: The MRT Line 4 will connect Kamalapur to Narayanganj at a length of just 16 kilometre. According to MAN Siddique the fourth and fifth metro rail will be completed by 2035. He also said that certain parts of MRT Line 2, 4 and 5 will be underground.
