Summary
The Border Roads Organisation (BRO) celebrated the 37th Raising Day of Project UDAYAK on 1 June 2026 at Doomdooma, Assam. Project UDAYAK is a specialised territorial project of the BRO responsible for developing and maintaining strategic roads, bridges, helipads, and border fencing in some of the most remote and difficult terrain of Northeast India — chiefly the easternmost districts of Arunachal Pradesh and parts of Assam, along the LAC with China and the Indo-Myanmar border.
Key takeaways:
- 37th Raising Day marked at Doomdooma with Swachhata Abhiyan, road safety awareness, a run and walkathon, medical and dental camps, and a Sainik Sammelan.
- Road network: Entrusted with over 1,457 km of road network in the easternmost regions of Arunachal Pradesh and parts of Assam.
- Name meaning: “Udayak” means the Rising Sun — the first rays of the rising sun in India fall within the project’s area of responsibility (AOR).
- Strategic frontier: Builds connectivity along the LAC and the Indo-Myanmar border, including border fencing to curb insurgency and illegal movement.
- 2025 milestones: 12 bridges, one road and one helipad were inaugurated by Raksha Mantri Shri Rajnath Singh in 2025.
- Civil-military integration & disaster response in remote tribal border hamlets.
Background & Concept
What is Project UDAYAK? A territorial project of the BRO that constructs and maintains strategic roads, bridges, helipads, and border fencing in the easternmost districts of Arunachal Pradesh and parts of Assam — connecting remote frontier villages to the LAC and the Indo-Myanmar border.
It was sanctioned by the government on 23 May 1989, after which Udayak was established on 1 June 1990, with headquarters at Doomdooma in the Tinsukia district of Assam — created during a period of heightened civil unrest and insurgency in Northeast India. Two task forces — 48 BRTF and 752 BRTF — were carved out of Projects Vartak and Sewak respectively to form the two executive arms of the Project. The name “Udayak” (Rising Sun) reflects its location at India’s eastern extremity.
Note on dating: Several current-affairs sources say “established 1989” (the sanction year), while the BRO counts the 1 June 1990 raising. Counting the raising year as the first, 2026 is the 37th Raising Day — both facts are correct; just be precise about sanction (1989) vs. raising (1990).

Answer Key with Explanations
▸ Q1 → (b) BRO — Ministry of Defence. Project UDAYAK is a territorial project of the Border Roads Organisation, which functions under the Ministry of Defence.
▸ Q2 → (b) The Rising Sun. It was named “Udayak” because the first rays of the rising sun in India fall within its area of responsibility (easternmost India).
▸ Q3 → (d) 1, 2 and 3. All three are correct — sanctioned 1989, raised 1 June 1990 at Doomdooma; task forces 48 BRTF and 752 BRTF were drawn from Projects Vartak and Sewak.
▸ Q4 → (d) 1, 2, 3 and 4. Its AOR covers Anjaw, Lohit, Dibang Valley, Longding, Tirap, and Changlang in eastern Arunachal Pradesh.
▸ Q5 → (a) 1 and 2 only. It works along the LAC and the Indo-Myanmar border. The Indo-Bangladesh border is unrelated to UDAYAK’s eastern AOR — Statement 3 is wrong.
▸ Q6 → (a) 1 and 2 only. Statement 3 is wrong — the BRO also builds roads in friendly neighbouring countries (e.g., Bhutan, Myanmar, Afghanistan). It was established in 1960 and is under the Ministry of Defence.
