India has launched a groundbreaking Rs 84 crore project to construct its first riverine lighthouses along the Brahmaputra River in Assam. Union Minister Sarbananda Sonowal laid the foundation stones on March 4, 2026, at sites including Pandu, Bogibeel, Silghat, and Biswanath Ghat.
In a historic step for inland navigation in India, Union Minister and Dibrugarh MP Sarbananda Sonowal has laid the foundation stone for India’s first riverine lighthouses in Assam a project that could dramatically improve safety, trade, and tourism along one of the country’s most powerful rivers.
Unlike traditional coastal lighthouses, these structures will guide vessels on an inland river system, marking a major technological shift in how India manages navigation on its waterways. With cargo traffic on the Brahmaputra rising rapidly, experts say the timing of the project could not be more crucial.
The foundation ceremony took place at Lachit Ghat and was jointly organised by the Directorate General of Lighthouses and Lightships and the Inland Waterways Authority of India under the Ministry of Ports, Shipping and Waterways.While India has dozens of lighthouses along its coastline, installing them along a river channel is something entirely new.
The Brahmaputra is known for its unpredictable nature its course shifts frequently, sandbars emerge and disappear, and thick fog during winter months often makes navigation risky. Local ferry operators and cargo pilots have long relied on experience and manual navigation aids.
Project Overview
These four solar-powered lighthouses, each 20 meters tall, will provide a 14-nautical-mile geographical range and 8-10 nautical miles luminous range for round-the-clock vessel guidance
Riverine lighthouses aim to change that reality.By installing visible, technologically advanced light systems at strategic points, authorities hope to create a reliable navigation framework that works even at night or during poor weather conditions.
Developed by the Directorate General of Lighthouses and Lightships (DGLL) and Inland Waterways Authority of India (IWAI), they address a 53% surge in cargo traffic on National Waterway-2 (NW-2) during 2024-25
The riverine lighthouses will be constructed at four important points along National Waterway 2, which stretches across Assam and forms one of India’s key inland transport corridors.The locations include
- Bogibeel
- Pandu
- Silghat
- Biswanath Ghat
These areas were chosen because they serve as critical navigation and transport points where cargo vessels, passenger ferries, and local boats frequently pass.By placing riverine lighthouses here, authorities hope to create a chain of guidance points along the Brahmaputra, helping vessels safely identify channels and avoid dangerous sandbanks.
Solar-Powered Technology Designed for the River
The project carries an estimated cost of ₹84 crore, and each riverine lighthouse will be around 20 metres tall.traditional lighthouses powered by grid electricity, these towers will run on solar energy, making them sustainable and suitable for remote riverbank locations.
Each lighthouse will have a geographical range of 14 nautical miles and a luminous range between 8 and 10 nautical miles.In simple terms, captains navigating the Brahmaputra will be able to see the guiding lights from several kilometres away offering critical direction during night travel or dense fog.
For cargo operators transporting goods such as tea, coal, food grains, and construction materials, this could mean fewer delays and safer voyages.One of the most interesting aspects of the project is that these riverine lighthouses will not function only as navigation aids.
Each site is planned as a multi-purpose riverfront destination.Facilities expected at the locations include
- A museum showcasing the history of river navigation
- An open-air amphitheatre for cultural events
- Cafeterias and visitor lounges
- Children’s play areas
- Souvenir shops
- Landscaped public spaces
Officials believe this approach will turn the riverine lighthouse sites into small tourism hubs, encouraging travellers to explore riverfront towns that often remain outside mainstream tourism circuits.For Assam, which is trying to expand river tourism through cruises and eco-tourism initiatives, this infrastructure could play a significant supporting role.
Economic and Strategic Impact
The initiative aligns with PM Narendra Modi’s vision to transform inland waterways into economic force multipliers.It responds to rising demand on Brahmaputra, India’s vital cargo corridor, enabling safer night navigation and reduced reliance on roads/rail.
Expected to spur tourism, the lighthouses could attract visitors to Assam’s scenic riverbanks, generating local revenue
The Brahmaputra waterway has quietly been undergoing a transformation.According to recent data, cargo movement along the river increased by more than 53 percent during the 2024–25 financial year.
As industries and logistics companies look for cheaper and greener transport alternatives, inland waterways are becoming increasingly attractive.Transporting goods by river can be far more fuel-efficient than road transport, reducing both costs and carbon emissions.
But for this system to work effectively, navigation safety must improve and that is where riverine lighthouses come in.By providing consistent guidance points along the river, the infrastructure could allow vessels to operate safely around the clock, significantly increasing the efficiency of river transport.Strategic locations along the 891-km NW-2 stretch from Dhubri to Sadiya will enhance safe navigation for tea, coal, and fertilizer transport amid the river’s shifting channels
Key Features and Tech
Each lighthouse integrates Automatic Identification Systems (AIS), weather sensors, and 24/7 lighting to support growing freight and passenger movement.
Tourism amenities like museums, amphitheatres, cafeterias, play areas, and souvenir shops will turn them into public landmarks.Fully solar-powered, they promote sustainability while boosting Assam’s economy through jobs and logistics efficiency
A Larger Vision for India’s Waterways
The Brahmaputra riverine lighthouse initiative is also part of India’s broader push to revive inland waterways as a major transport network.Over the past decade, the government has invested heavily in river terminals, dredging operations, and digital navigation systems.
The Northeast region, due to its strategic geography and river network, plays an important role in this plan.If the Brahmaputra project proves successful, experts believe similar riverine lighthouse systems could be introduced along other major waterways in India, creating a new standard for inland navigation.
What Local Communities Gain
Beyond logistics and tourism, the project could also benefit communities living along the Brahmaputra.Construction and maintenance work will generate local employment, while tourism infrastructure could create opportunities for small businesses, guides, and hospitality services.
For residents of river towns, the riverine lighthouses may eventually become both a symbol of progress and a new cultural landmark.
Future Outlook
Completion timelines aim for operational readiness by late 2026 or early 2027, pending construction progress.This project sets a precedent for other Indian rivers, potentially expanding NW network capabilities nationwide.
FAQ
1.What is a riverine lighthouse?
A riverine lighthouse is a navigation tower built along rivers to guide boats and ships safely through waterways.
