Dhaka Mobility in Limbo: BRT-3 Shelved, MRT Lines Delayed, and the $5 Billion Annual Congestion Cost
BRT Line 3 abandoned after 13 years; MRT Line 1 slips to 2030; peak-hour speed below 7 km/h; governance fragmentation unresolved
BDPolicy Lab · 2026-05-20
Dhaka's urban transport system is in institutional paralysis. The Bus Rapid Transit Line 3 -- Bangladesh's first and only BRT project -- was formally shelved after ECNEC rejected its fourth cost revision on July 27, 2025, having consumed Tk 2,800 crore over 13 years without ever running a revenue service. MRT Line 1, the underground corridor from Hazrat Shahjalal International Airport to Kamalapur, has slipped four years beyond its 2026 target and will not open before 2030. Meanwhile, Dhaka's average peak-hour traffic speed has fallen to below 7 km/h, generating an estimated $4-6 billion in annual economic losses -- roughly 2-3 percent of national GDP -- through time waste, fuel burn, and foregone productivity. MRT Line 6 (Uttara-Motijheel) remains the sole operational mass rapid transit corridor; MRT Line 5 Northern Route is under construction with a 2028 target. Transport Minister Shaikh Rabiul Alam has pledged reforms across road, rail, and shipping, but no published roadmap addresses Dhaka's mobility crisis specifically.
Key findings
- BRT Line 3 shelved after 13 years and Tk 2,800 crore spent: the 223 percent cost overrun made the fourth revision indefensible. The Greater Dhaka Sustainable Urban Transport Project (BRT Line 3, Dhaka Airport to Gazipur) was approved in 2012 at Tk 2,039.84 crore. By May 2025, Tk 2,800.62 crore had been spent with 77 percent physical progress and zero revenue-service days. The Roads and Highways Department submitted a fourth revision seeking to raise the total to Tk 6,597.32 crore -- a 223 percent overrun on the original estimate. ECNEC rejected the proposal on July 27, 2025; Planning Adviser Wahiduddin Mahmud described it as 'a monstrous and unplanned mega-project' and ordered a probe. The interim government will not initiate BRT service; the decision on the project's final form passes to the elected BNP government. (Sources: The Business Standard, 'Costly delays and doubts: BRT project spirals further with 55% cost jump'; ECNEC proceedings July 27, 2025; Bangladesh Pratidin English, August 18, 2025.)
- MRT Line 1 has slipped to 2030: a four-year delay on a corridor that Dhaka's north-south mobility depends on most urgently. MRT Line 1 (Hazrat Shahjalal International Airport to Kamalapur, 31.24 km total, including 19.87 km underground) was designed to provide Dhaka's first airport-to-city-centre rapid transit link. The original completion target was December 2026. DMTCL officials confirmed in 2025 that this deadline is 'no way possible'; the revised target is December 2030 -- a four-year slip. Physical construction was slow to begin: the depot land was only 75 percent developed as of November 2024, with main civil tenders invited in January 2025. The delay means Dhaka's densest commute corridor -- Airport Road to Motijheel -- will remain without grade-separated transit for at least five more years.

- Congestion costs Bangladesh an estimated $4-6 billion per year: 3.2 million working hours lost every day in Dhaka alone. The World Bank Integrated Corridor Management Dhaka North Project (P177702, 2022) documents 3.2 million working hours lost daily to Dhaka congestion. The Accident Research Institute (ARI) at BUET estimates the annual economic loss at Tk 56,000 crore (approximately $6.5 billion) in 2020, up from Tk 37,000 crore ($4.35 billion) in 2018. World Bank analysis places the direct GDP drag at 2-3 percent annually. Average peak-hour traffic speed in Dhaka has declined from 21 km/h in 2004 to below 7 km/h -- a 67 percent deterioration that has accelerated despite successive road-widening and flyover investments. (Sources: World Bank P177702 project document; ARI BUET congestion studies; TBS, 'Dhaka traffic congestion eats up 2.9% of GDP'.)
- Road deaths exceed 30,000 annually by WHO estimates: police-reported figures are six times lower and mask the true toll. The WHO Global Status Report on Road Safety 2023 estimates approximately 31,578 road crash deaths annually in Bangladesh -- nearly six times the police-reported figure. BRTA recorded 5,024 deaths in 2023 and 5,840 in 2024 (administrative data). The Bangladesh Jatri Kalyan Samity, which surveys hospital records, reported 8,543 killed in 2024 -- still less than one-third of the WHO estimate. The gap reflects chronic underreporting: deaths that occur after hospital admission, outside police jurisdiction, or on rural roads are routinely excluded from BRTA counts. The true national toll places Bangladesh among the world's most dangerous road environments per 100,000 population. (Sources: WHO Global Status Report on Road Safety 2023; The Daily Star, '8,543 killed on roads in 2024'; TBS, 'Road accidents claim 8,543 lives in 2024, Jatri Kalyan Samity'.)
- Governance fragmentation is the structural cause: DTCA, BRTA, RHD, RAJUK, and DMTCL each control a slice of Dhaka's transport, with no unified authority. Five agencies overlap on Dhaka transport governance without a coordinating mandate with enforcement power: the Dhaka Transport Coordination Authority (DTCA) nominally coordinates but lacks operational authority; the Bangladesh Road Transport Authority (BRTA) registers vehicles and licenses drivers; the Roads and Highways Department (RHD) manages national roads through the city; RAJUK plans land use without integrating transport infrastructure; and the Dhaka Mass Transit Company Limited (DMTCL) operates and builds MRT lines with no formal interface to the bus network. The BRT Line 3 debacle illustrates the consequence: 13 years of cost revisions passed through multiple ECNEC reviews without any authority able to cancel the project at year three when design flaws first became apparent. Minister Rabiul Alam's portfolio spans Road Transport, Railways, and Shipping, but DTCA and DMTCL remain under separate administrative channels.

The average peak-hour vehicle in Dhaka travels at less than 7 kilometres per hour. A
pedestrian walking briskly is faster. This is not a recent development: the World Bank
documented the decline from 21 km/h in 2004, but the trajectory has not reversed. Every
year that passes without functioning mass rapid transit adds another cohort of commuters
to a road network that cannot absorb them.
The economic arithmetic is brutal. The Accident Research Institute at BUET estimates that
Dhaka's congestion consumed Tk 56,000 crore -- approximately $6.5 billion -- in economic
losses in 2020 alone, up from $4.35 billion in 2018. The World Bank calculates 3.2
million working hours lost every day in the city. At Bangladesh's average wage, that
is a recurring daily tax on productivity with no corresponding service received.
Thirteen Years and No Buses: The BRT Line 3 Autopsy
Bangladesh's first bus rapid transit project launched in 2012 with an approved budget of
Tk 2,039.84 crore and a target completion date of December 2016. By May 2025, Tk 2,800
crore had been spent, 77 percent of physical work was nominally complete, and not a
single revenue passenger had boarded a BRT bus.
The project's problems were never just financial. The dedicated bus lanes -- the
core feature that makes BRT function -- were incompatible with the road's actual geometry
at multiple junctions. Corridor design conflicts were flagged in successive reviews but
not resolved. The Roads and Highways Department (RHD) submitted a fourth revision in
mid-2025 seeking a further Tk 3,760 crore and a four-year extension to 2029.
The ECNEC rejected it on July 27, 2025. Planning Adviser Wahiduddin Mahmud called the
project "a monstrous and unplanned mega-project" and ordered an investigation. The
practical consequence: the interim government has effectively abandoned it, while the
partially built infrastructure -- stations, depots, partial lane markings -- sits idle
on one of Dhaka's most congested corridors.
The BNP government under Prime Minister Tarique Rahman, which assumed office in February
2026, has not announced a formal position on the project's future. Transport Minister
Shaikh Rabiul Alam's public statements have not addressed BRT Line 3 specifically. The
probe committee's findings, when published, will determine whether Tk 2,800 crore of
sunk cost can be converted into any functional transit infrastructure or whether it is
a write-off.
MRT: One Line Running, Four Years of Delays on the Next
MRT Line 6 (Uttara to Motijheel, 20.1 km) is operational and carrying passengers.
It opened in stages: Uttara to Agargaon in December 2022, and the Agargaon to Motijheel
extension in December 2023. For commuters in that corridor, it represents a genuine
service improvement.
Every other MRT line in Dhaka's network plan is behind schedule.
MRT Line 1 -- the underground corridor from Hazrat Shahjalal International Airport to
Kamalapur (31.24 km, of which 19.87 km underground) -- was designed to open in December
- DMTCL officials confirmed in 2025 that this deadline is not achievable; the revised
target is December 2030, a four-year slip. The delay is structural: as of November 2024,
depot land development was only 75 percent complete and main civil tenders had not yet
been awarded. A project that requires years of underground tunnelling in a dense urban
environment cannot recover four years of schedule slip by accelerating construction.
MRT Line 5 Northern Route (Hemayetpur to Bhatara, 20 km) broke ground in November 2023
and is targeting 2028 completion, funded primarily by JICA. MRT Line 5 Southern Route
(Gabtoli to Dasherkandi, 17.4 km) has completed its feasibility and design phase with
ADB support and is awaiting investment-project approval.
The network as planned would give Dhaka meaningful mass transit coverage. The network
as being built is running four to five years behind the plan on every line except Line 6.
The Road Safety Emergency
Dhaka's congestion is visible and measured in hours lost. Road deaths are less visible but
far larger in scale. The WHO Global Status Report on Road Safety 2023 estimates approximately
31,578 road crash deaths annually across Bangladesh -- nearly six times the 5,024 deaths
BRTA recorded in 2023 from police reports. The Jatri Kalyan Samity, using hospital and
field monitoring, reported 8,543 killed in 2024, still less than one-third of the WHO figure.
The gap is not statistical noise. Deaths that occur hours after a crash, outside police
coverage, or on roads where no report is filed are systematically excluded from BRTA counts.
The undercount is a policy problem: it allows road safety to be treated as a manageable
problem when the actual toll places Bangladesh among the world's most dangerous road
environments per capita.
Minister Rabiul Alam has announced a driver training programme and the creation of a
National Crash Database -- a genuine improvement if implemented. But neither addresses
the two structural causes: a vehicle fleet growing faster than infrastructure, and a
prosecution rate for traffic violations that is not a credible deterrent.
The Governance Gap That No Minister Can Fill Alone
Bangladesh's national vehicle fleet reached approximately 5.75 million registered vehicles
nationally (per Jatiya Sangsad records, 2023), with Dhaka accounting for roughly 40-45
percent of registrations. Every newly registered vehicle joins a road network that has
not expanded commensurably.
Five agencies govern pieces of Dhaka's transport system without a unified authority. DTCA
coordinates in name but lacks enforcement power. BRTA registers vehicles and licenses
drivers. RHD controls national highways running through the city. RAJUK plans land use
without transport-integrated zoning. DMTCL operates and builds MRT lines with no
formal interface to the bus or rickshaw networks that millions of Dhaka residents depend on.
This fragmentation produced BRT Line 3: a project approved by one body, designed by
another, revised repeatedly by a third, and finally rejected by a fourth -- with no single
authority able to cancel it at year three when the design flaws first surfaced. It will
produce the next such failure unless governance reform precedes the next project approval.
What the BNP Government Has Not Yet Done
Minister Rabiul Alam holds the largest transport portfolio in Bangladeshi history --
Road Transport, Bridges, Railways, and Shipping in a single ministry. The consolidation
creates the possibility of coordinated policymaking across modes. What has not yet appeared
is a published urban mobility policy for Dhaka: one that addresses the BRT legacy,
sets accountability targets for MRT Line 1, integrates the bus network with MRT Line 6,
and assigns DTCA the enforcement authority it currently lacks.
The city that moves at 7 km/h during peak hours cannot become a productive capital city
through infrastructure investment alone. The institutions that plan, fund, approve, and
operate transport projects need structural reform before the next large project is approved.
The BRT Line 3 file is a 13-year, Tk 2,800 crore argument for that reform.
Data and methodology
Congestion cost. The $4-6 billion annual loss range is derived from two independent sources. The ARI (BUET) methodology uses vehicle operating cost surveys, time-loss valuation at wage rates, and fuel waste estimates; figures are Tk 37,000 crore (2018 base) and Tk 56,000 crore (2020 base) converted to USD at prevailing exchange rates. The World Bank P177702 project document (2022) corroborates via a working-hours-lost metric (3.2 million hours/day) and a 2-3 percent GDP direct-cost range. These are not directly comparable methodologies; the range acknowledges the spread. Traffic speed. The 21 km/h to below-7 km/h decline is cited in the World Bank P177702 document and independently corroborated by the UNESCAP Sustainable Urban Transport Index (SUTI) report for Dhaka and Dhaka Tribune reporting of ARI data. BUET ARI records corridor-level speeds as low as 4.8 km/h in the most congested areas. The 7 km/h figure is used as the verified upper bound for peak-average speed. Road safety. Administrative fatality counts (BRTA) are from BRTA annual reports and TBS/Daily Star reporting. The WHO estimate (~31,578/yr) is from the WHO Global Status Report on Road Safety 2023, which applies hospital-registry and police-record correction factors. The Jatri Kalyan Samity figure (8,543 in 2024) uses press and hospital-based NGO monitoring. All three figures are reported; the WHO estimate is used as the primary reference for the '30,000+' characterisation. BRT cost overrun. Original cost Tk 2,039.84 crore from 2012 ECNEC approval. Fourth revision amount Tk 6,597.32 crore from RHD proposal as reported by TBS. Percentage overrun = (6,597.32 - 2,039.84) / 2,039.84 = 223.4%, rounded to 223%. Cumulative spend Tk 2,800.62 crore and physical progress 77.48% from Planning Commission data as of May 2025 (TBS reporting). MRT delays. Target dates and revised dates from DMTCL official statements as reported by The Daily Star.
