Introduction
The Gorakhpur–Siliguri Expressway is a four-lane, access-controlled road planned under the Bharatmala Pariyojana. It is designed to run alongside NH-27, close to the India-Nepal border. The highway avoids populated areas, allowing rapid, interruption-free travel. Built using EPC mode, it ensures better control over cost and deadlines. It is a direct link—connecting Uttar Pradesh’s Gorakhpur with West Bengal’s Siliguri. Operated by NHAI, this greenfield corridor runs nearly 520 km, bypassing crowded zones and bridging gaps in India’s eastern road network.
How Far, How Fast?
This highway will cut the travel time between Gorakhpur and Siliguri from 15 hours to 6. Without a direct route now, most vehicles take longer, congested paths. The new corridor gives an alternate, shorter link that skips city roads and busy intersections.
| Particulars | Details |
| Length | 519.6 km |
| Expected Completion | December 2025 |
| Estimated Cost | ₹32,000 crore |
| Lanes | 4 (expandable to 6) |
| Route Type | Greenfield |
| States Covered | Uttar Pradesh, Bihar, West Bengal |
Where Will It Go?
The expressway starts at Jagdishpur in Gorakhpur. It cuts through Tamkuhiraj in Kushinagar and heads into Gopalganj in Bihar. After crossing nine districts in Bihar, including Champaran, Sitamarhi, Darbhanga, and Kishanganj, it enters Siliguri, West Bengal.
| State | Distance Covered |
| Uttar Pradesh | 84.3 km |
| Bihar | 416.2 km |
| West Bengal | 18.97 km |
What Are the Benefits?
The expressway improves travel speed, boosts regional trade, and connects neglected regions to India’s mainstream economy.
- Cuts travel time between UP and Bengal, linking Siliguri faster to central India
- Connects agricultural and industrial hubs. This facilitates the growth of industrial corridors along the highway.
- Boosts jobs and real estate development, improves access to markets, especially for farmers
Districts in Bihar like Darbhanga, Madhubani, and Supaul are set to benefit the most. Previously isolated, these regions now get fast access to metro markets. UP districts like Deoria and Kushinagar will also see rising demand for land and housing.
Conclusion
The Gorakhpur–Siliguri Expressway is more than an infrastructure project. It is a development catalyst—unlocking trade, employment, and investment across India’s eastern belt. By reducing travel time and improving access, this 6-lane-ready expressway will bring real, lasting change to regions that have long awaited attention.
