Prime Minister Narendra Modi inaugurated the Delhi-Dehradun Expressway, a 210-km highway built at Rs 11,868 crore, featuring Asia's largest wildlife elevated corridor to mitigate ecological impact while enhancing connectivity.
Key points
Delhi-Dehradun Expressway reduces travel time from 6.5 hours to 2.5 hours and distance from 235 km to 210 km, boosting regional connectivity and economic activity.
Wildlife Corridor: A 10.97 km animal underpass, including Asia’s largest elevated wildlife corridor (6-7 metres high), ensures safe animal movement through Rajaji Tiger Reserve, reducing human-wildlife conflict.
Environmental Mitigation: Compensatory afforestation on 165.5 hectares with 1,95,000 trees planted, alongside Rs 40 crore eco-restoration works, addresses forest land diversion concerns.
[GS3-Environment] The project aligns with India’s National Wildlife Action Plan (2017-2031) by promoting genetic exchange among species and biodiversity conservation.
Carbon Reduction: Projected to reduce CO2 emissions by 240 million tonnes over 20 years, equivalent to 6-6.8 million trees, with 19% fuel savings due to shorter routes.
Wildlife Institute of India (WII) study documented 18 species using underpasses, including elephants, validating corridor effectiveness for large mammals.
[GS2-Governance] The project exemplifies integrated infrastructure governance, balancing development (Article 39(b) of DPSP) with environmental protection (Article 48A).
Way Forward: Scale wildlife corridors in future highway projects, mandate real-time ecological monitoring via WII, and institutionalize green infrastructure norms in NHAI policies.
Key terms
- Compensatory Afforestation
- A legal mandate under the Forest (Conservation) Act, 1980, requiring afforestation on non-forest land equivalent to diverted forest area. Managed by CAMPA funds, it aims to maintain ecological balance but faces criticism for poor survival rates of planted trees.
- Wildlife Institute of India (WII)
- An autonomous institution under MoEFCC, established in 1982. It conducts wildlife research, advises on conservation policies (e.g., NTCA), and trains forest officers, playing a pivotal role in Project Tiger and Elephant.
- National Highway Authority of India (NHAI)
- A statutory body under MoRTH, established in 1988 via NHAI Act. It implements Bharatmala Pariyojana, manages PPP projects, and enforces environmental safeguards like green highways policy.
- Rajaji Tiger Reserve
- A protected area in Uttarakhand spanning 820 sq km, merging Rajaji National Park and Motichur Wildlife Sanctuary. It is critical for tiger conservation (Project Tiger) and elephant corridors under the Wildlife Protection Act, 1972.

Answer framework
Introduction
Briefly introduce the Delhi-Dehradun Expressway project, highlighting its significance in reducing travel time and distance while addressing ecological concerns.
Wildlife Conservation Measures
Implementation of Asia’s largest elevated wildlife corridor (10.97 km) to ensure safe animal movement through Rajaji Tiger Reserve.
Wildlife Institute of India (WII) study documenting 18 species using underpasses, validating corridor effectiveness.
Alignment with India’s National Wildlife Action Plan (2017-2031) to promote genetic exchange and biodiversity conservation.
Environmental Mitigation Strategies
Compensatory afforestation on 165.5 hectares with 1,95,000 trees planted to offset forest land diversion.
Rs 40 crore allocated for eco-restoration works to address ecological balance.
Projected reduction in CO2 emissions by 240 million tonnes over 20 years, equivalent to 6-6.8 million trees.
Governance and Policy Integration
Exemplifies integrated infrastructure governance balancing development (Article 39(b) of DPSP) with environmental protection (Article 48A).
Role of National Highway Authority of India (NHAI) in enforcing environmental safeguards like green highways policy.
Conclusion
Suggest scaling wildlife corridors in future projects, mandating real-time ecological monitoring, and institutionalizing green infrastructure norms in NHAI policies for sustainable development.
