Dhaka–Sylhet Highway is a major arterial national highway connecting Dhaka and Sylhet in Bangladesh. Serving as a spine for passenger, freight, and intercity connectivity, the route links metropolitan hubs, industrial zones, and tourism centers. The corridor interfaces with ports, airports, and railheads, integrating with regional transport networks involving Dhaka International Airport, Shahjalal International Airport, and the Bangladesh–India border gateway at Tamabil.

Route description

The highway begins near central Dhaka and proceeds northeast through municipal and rural districts including Gazipur District, Tongi, Mymensingh, Dhaka Division, Kishoreganj District, Netrokona District, Sunamganj District, and into Sylhet Division. Major interchanges connect to corridors leading toward Chittagong, Cumilla, Khulna, and cross-border links toward Shillong and Dawki in India. Along the corridor it passes near industrial clusters such as the DPZs in Gazipur, agricultural markets like Bara Bazar (Sylhet), cultural sites linked to Sylhet Sadar Upazila, and natural attractions proximate to Ratargul Swamp Forest and Lawachara National Park. The route intersects national arteries including N1 (Bangladesh), N3 (Bangladesh), and feeder roads to Dhaka–Chittagong Highway and regional linkages to Asian Highway Network alignments.

History and development

The highway evolved from colonial-era trackways used during the British Raj and subsequent improvements during the Pakistan period (1947–1971). Post-independence development accelerated under initiatives by successive administrations including projects overseen during the tenures of leaders such as Sheikh Mujibur Rahman and later cabinets. Multilateral financing from institutions like the Asian Development Bank, World Bank, and cooperation with Japan International Cooperation Agency contributed to expansion phases. Landmark milestones include widening projects during the 1990s and early 2000s, upgrade initiatives concurrent with national five-year plans coordinated by the Planning Commission (Bangladesh), and later safety and capacity improvements influenced by studies from Bangladesh University of Engineering and Technology researchers.

Infrastructure and design

The corridor features two to four lane segments with sections designed to national trunk specifications set by the Roads and Highways Department (Bangladesh). Civil engineering works on the route include reinforced concrete bridges over rivers such as the Surma River, elevated bypasses near urban centers like Moulvibazar, drainage schemes accommodating monsoon flows, and pavement technologies informed by research from Bangladesh Council of Scientific and Industrial Research. Design standards reference international norms promoted by the International Road Federation and construction practices executed by contractors including China Communications Construction Company and regional firms. Ancillary infrastructure comprises toll plazas, bus terminals linked to operators such as BRTC, petroleum depots servicing fleets of Tata Motors and Isuzu trucks, and signage conforming to guidelines from the Bangladesh Road Transport Authority.

Traffic and safety

Traffic on the highway includes long-haul freight, intercity coaches, private vehicles, and two-wheelers, with seasonal peaks during festivals tied to Eid al-Fitr, Eid al-Adha, and the Pohela Boishakh. Accident statistics compiled by the Bangladesh Police and road safety audits by BRAC and SNV Netherlands Development Organisation highlight congestion, head-on collisions, and pedestrian risks in peri-urban stretches. Enforcement efforts involve checkpoints by the Traffic Police (Bangladesh) and regulatory action under the Road Transport Act, 2018 (Bangladesh). Countermeasures have included installation of median barriers, reflective delineators, speed calming near market towns, and public safety campaigns in collaboration with United Nations Road Safety Collaboration partners.

Economic and social impact

The highway underpins economic flows between Sylhet Division and the Dhaka Metropolitan Area, facilitating remittance-driven consumption linked to expatriate communities in United Kingdom, United States, and the Middle East. It enables access to tea estates managed by companies such as Kazi & Kazi Tea Estate and agro-processing units in Sylhet while supporting supply chains to garment manufacturing clusters in Gazipur and wholesale trade in Karwan Bazar. Socially, the corridor affects migration patterns, rural-urban commuting for employment at institutions like Bangabandhu Sheikh Mujib Medical University and cultural exchange centered on sites including Hazrat Shah Jalal Mazar. The highway also supports tourism flows to religious and ecological attractions, impacting hospitality operators and local markets.

Maintenance and governance

Responsibility for routine maintenance and capital works rests with the Roads and Highways Department (Bangladesh) under policy oversight from the Ministry of Road Transport and Bridges (Bangladesh). Budgeting aligns with allocations in national development programs and donor-financed projects managed in coordination with Implementation Monitoring and Evaluation Division (Bangladesh). Contracting follows procurement rules influenced by the Public Procurement Act (Bangladesh) and performance monitoring includes asset registers and pavement condition surveys conducted in partnership with universities such as Bangladesh University of Engineering and Technology and consultancy firms like AECOM.

Future projects and upgrades

Planned interventions include corridor widening to expressway standards, construction of bypasses around congested nodes like Mymensingh, enhanced bridge replacements over flood-prone waterways, and integration with proposed high-capacity corridors promoted by the Asian Highway Network and regional initiatives within the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation. Proposals under consideration involve smart traffic management systems, elevated sections to mitigate flooding, and linkages to proposed rail upgrades overseen by Bangladesh Railway to create multimodal transport hubs serving Hazrat Shahjalal International Airport and border crossings at Tamabil.
