Source-derived summary

The MRT Line 4 (Bengali: এমআরটি লাইন ৪) of Dhaka Metro Rail is a proposed mass rapid transit line, stretching from Dhaka city's main railway station to Madanpur. This line is scheduled to be completed by 2030 and will be operated by the Dhaka Mass Transit Company Limited (DMTCL). South Korea has expressed interest to invest in this project.

History

In 2005, the World Bank published a study report, recommending that the government of Bangladesh build a mass transit system in Dhaka. In the same year, American consultancy firm Louis Berger Group prepared a strategic transport plan for Dhaka. The World Bank helped to develop this plan, which proposed the construction of five MRT lines in Dhaka. The five metro lines were MRT Line 1, MRT Line 2, MRT Line 4, MRT Line 5 and MRT Line 6. In 2017, an agreement was signed between the government of Bangladesh and Japan to build MRT Line 4 on a Public Private Partnership (PPP) basis. On 1 October 2019, Selina Hayat Ivy, the mayor of Narayanganj City Corporation submitted a written request to Obaidul Quader, the Road Transport and Bridges minister, to connect Narayanganj with the Dhaka Metro network. Although, there was an existing plan to connect the city with Kamalapur by building MRT Line 4 which was proposed to be an underground line parallel with the Narayanganj–Bahadurabad Ghat line.

Why this record matters

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 14, 2026.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
