In a landmark decision for Northeast India, the Union Cabinet, chaired by Prime Minister Narendra Modi, approved a Rs 22,864 crore greenfield highway project on April 30, 2025, to connect Shillong in Meghalaya with Silchar in Assam. This 166.80 km four-lane corridor promises to slash travel times, enhance regional connectivity, and unlock economic opportunities for millions across the Northeast. For communities long challenged by difficult terrain and monsoon-related disruptions, this project offers hope for smoother journeys, thriving businesses, and a brighter future.
A Game-Changing Infrastructure Project
The Shillong-Silchar Greenfield Highway Project entails the development, maintenance, and management of a four-lane, access-controlled high-speed corridor stretching from Mawlyngkhung (near Shillong) in Meghalaya to Panchgram (near Silchar) in Assam. With a total length of 166.80 km, the highway covers 144.80 km in Meghalaya and 22 km in Assam. Executed under the hybrid annuity mode, the project balances public funding with private investment, ensuring efficient construction and long-term maintenance. The estimated cost of Rs 22,864 crore reflects the scale and ambition of this initiative, which builds on earlier plans conceived under the Bharatmala programme in 2017.

Revolutionizing Regional Connectivity
The new corridor is poised to redefine travel across Northeast India by significantly reducing both distance and time between major cities. It will connect Guwahati, Shillong, Silchar, Imphal, Aizawl, and Agartala, creating a robust network for commuters, businesses, and tourists. Reports suggest the highway could cut travel time between Shillong and Silchar to approximately four hours, a marked improvement over the current route plagued by poor road conditions and landslides, especially along stretches like Sonapur-Ratacherra. This enhanced connectivity will also benefit Tripura, Mizoram, Manipur, and Assam’s Barak Valley, fostering stronger ties with mainland India and improving logistics efficiency.
The project integrates with key national highways, including NH-27, NH-106, NH-206, and NH-37, ensuring seamless access to towns like Diengpasoh, Ummulong, Phramer, Khliehriat, Ratachera, Umkiang, and Kalain. By alleviating congestion on the existing NH-06, particularly in Meghalaya’s East Jaintia Hills, the corridor addresses long-standing commuting challenges, especially during the monsoon season when landslides disrupt travel.
Boosting Economic Growth and Industry
The Shillong-Silchar Corridor is expected to catalyze economic development across the Northeast. In Meghalaya, the highway passes through regions rich in cement and coal production, providing a vital lifeline for these industries to access broader markets. Improved road infrastructure will lower transportation costs, enhance supply chain efficiency, and attract investment to the region. The project’s economic ripple effects are likely to extend to Assam, Manipur, Mizoram, and Tripura, creating new opportunities for trade and commerce.
Beyond industry, the corridor will support the Northeast’s growing logistics sector. By reducing travel times and improving road reliability, it aligns with national goals to enhance logistics efficiency, a critical component of India’s economic competitiveness. The project’s focus on greenfield development—building a new alignment rather than expanding existing roads—ensures a modern, high-capacity corridor designed to meet future demands.
A Boon for Tourism
The Northeast’s breathtaking landscapes, from Meghalaya’s rolling hills to Assam’s vibrant cultural hubs, have long attracted tourists. The Shillong-Silchar Highway will amplify this potential by connecting major airports in Guwahati, Shillong, and Silchar, making the region more accessible to national and international visitors. The corridor will link scenic destinations, promoting tourism and supporting local businesses like homestays, restaurants, and handicraft markets.
By integrating with existing NH-06, the highway will provide a smoother, more reliable route for tourists exploring the Northeast’s natural and cultural treasures. This infrastructure boost is expected to elevate the region’s profile as a must-visit destination, contributing to economic growth and community development.
Socio-Economic Transformation
The Shillong-Silchar Corridor is more than a road—it’s a catalyst for socio-economic transformation. The project is anticipated to generate significant employment opportunities during construction and beyond, benefiting communities in Meghalaya, Assam, Manipur, Mizoram, and Tripura. From skilled engineers to local laborers, the highway will create jobs and stimulate economic activity in some of India’s most underserved regions.
The project aligns with the government’s vision of Atmanirbhar Bharat, emphasizing self-reliance through infrastructure development. By fostering economic opportunities and improving access to education, healthcare, and markets, the corridor will uplift living standards and empower communities across the Northeast.
Strategic and Defense Benefits
In addition to its economic and social impacts, the Shillong-Silchar Highway holds strategic importance. The Northeast shares borders with several countries, and efficient road networks are critical for the swift movement of defense forces. The corridor will enhance India’s strategic capabilities in the region, ensuring faster and more reliable access for military operations if needed. This dual-purpose infrastructure underscores the project’s significance for both civilian and national security interests.
Alignment with PM Gati Shakti National Master Plan
The Shillong-Silchar Corridor is a key component of the PM Gati Shakti National Master Plan, which aims to create an integrated, multimodal infrastructure network across India. By linking with major transport corridors and prioritizing seamless connectivity, the project supports the plan’s vision of reducing logistics costs and boosting economic growth. The corridor’s greenfield design and focus on high-speed, access-controlled travel reflect a forward-thinking approach to infrastructure development, positioning the Northeast as a hub of connectivity and opportunity.
Overcoming Past Challenges
The project addresses long-standing issues with the existing NH-06, which has deteriorated in several stretches, particularly in Meghalaya’s East Jaintia Hills. Technical difficulties have prevented the expansion of the current highway, making a new greenfield alignment the most effective solution. Earlier cost estimates for the project, reported at Rs 25,000 crore in January 2025, have been refined to Rs 22,864 crore, reflecting careful planning and optimization by the government.
A Vision for the Future
The approval of the Shillong-Silchar Greenfield Highway Project marks a pivotal moment for Northeast India. By bridging geographical divides, fostering economic growth, and promoting tourism, this corridor will transform the region’s infrastructure landscape. As construction progresses, the highway is set to become a symbol of progress, connecting communities and unlocking the Northeast’s vast potential for generations to come.
