Kolkata-Northeast Sea Route to Bypass Bangladesh
May 17, 2025

Why in News?

India is planning a new highway from Shillong (Meghalaya) to Silchar (Assam) as part of a broader multi-modal transport project connecting to Myanmar, which will create a sea route to Kolkata that bypasses Bangladesh.

This move is seen as a strategic response to Bangladesh’s interim leader Muhammad Yunus, who recently claimed that Northeast India is “landlocked” and relies on Dhaka as its only ocean gateway.

In response, PM Modi, during a meeting with Yunus at the BIMSTEC Summit, cautioned against divisive rhetoric.

  • Strategic Highway to Transform North-East Connectivity

Kaladan Multi-Modal Transit Transport Project (KMTTP)

  • The KMTTP is a strategic infrastructure initiative undertaken by India, aimed at enhancing connectivity between the eastern Indian seaport of Kolkata and the landlocked North-Eastern states via Myanmar, bypassing Bangladesh.
  • The project is jointly developed by India and Myanmar and is a key component of India’s Act East Policy.
  • Different Legs of the Project
    • Sea Leg
      • From Kolkata Port (India) to Sittwe Port (Myanmar) via the Bay of Bengal.
      • Distance: ~539 km by sea.
      • Sittwe Port has been constructed by India.
    • Inland Waterway Leg
      • From Sittwe to Paletwa via the Kaladan River in Myanmar.
      • Distance: ~158 km.
    • Road Leg
      • From Paletwa to Zorinpui (on the India-Myanmar border in Mizoram).
      • Distance: ~110 km.
    • Indian Leg (Planned Extension)
      • From Zorinpui to Lawngtlai, and further to Aizawl in Mizoram.
      • To be connected to India's highway network.
  • Benefits
    • Bypasses Bangladesh: Reduces dependency on access through Bangladesh for North-East connectivity.
    • Improves Connectivity: Offers an alternative route to the Siliguri Corridor (Chicken’s Neck), the narrow strip that connects North-East India with the rest of the country.
    • Boosts Trade & Commerce: Enhances trade flow between India and South-East Asia.
    • Strategic Significance: Strengthens India’s presence in the Bay of Bengal and deepens ties with Myanmar.
    • Economic Development: Spurs infrastructure development and economic activities in India’s underdeveloped North-Eastern region.
    • Part of Act East Policy: A critical step in India’s efforts to improve connectivity with ASEAN countries.

Strategic Highway to Transform North-East Connectivity

  • A 166.8-km four-lane high-speed highway is being constructed from Mawlyngkhung (near Shillong) to Panchgram (near Silchar) along NH-6.
  • It is the first high-speed corridor in the North-East and the first such project in a hilly region, to be completed by 2030.
  • The project is implemented by NHIDCL for MoRTH and was approved by the Union Cabinet at a cost of Rs 22,864 crore.
  • Infrastructure Details
    • The project will be executed in Hybrid Annuity Mode (HAM) under the PPP model.
      • HAM is a project delivery model used in India, particularly for national highway development.
      • It combines elements of both the Engineering, Procurement, and Construction (EPC) and the Build, Operate, and Transfer (BOT) models
      • It involves the government providing a portion of the project cost (40%) as construction support, while the remaining 60% is financed by the private developer through a pre-fixed annuity payment. 
      • This model aims to reduce financial risk for developers and speed up project execution. 
    • It will feature:
      • 19 major bridges, 153 minor bridges, 326 culverts
      • 22 underpasses, 26 overpasses, 8 limited-height subways
      • 34 viaducts to navigate the hilly terrain.
  • Key National and Strategic Significance
    • The highway will reduce travel time between Shillong and Silchar from 8.5 hours to 5 hours.
    • It will connect Silchar — a key entry point to Mizoram, Tripura, Manipur, and the Barak Valley — and act as a major regional link.
    • It supports India’s Act East Policy by enhancing connectivity to Myanmar and beyond.
    • The project is expected to reduce dependence on the Siliguri Corridor (Chicken’s Neck) and bypass Bangladesh, offering an alternative route via the Kaladan Multi Modal Transit Transport Project.
