Construction Begins Soon on Kozhikode–Wayanad Twin Tunnel

19 Jun 2025 CW Team

Stretching approximately 8.17 kilometres from Anakkampoyil in Kozhikode to Kalladi near Meppadi in Wayanad, the new route is expected to reduce travel distance by around 40 kilometres and cut journey time considerably. The tunnel will be the third-longest road tunnel in India, designed to enhance regional transport links and economic development.

Execution will be via a tripartite agreement among the Kerala Infrastructure Investment Fund Board (KIIFB), Konkan Railway Corporation, and the Public Works Department. The contract has been awarded to Dilip Buildcon, with Royal Infrastructure assigned the construction of a 17.5 km approach road between Thiruvambady and Marippuzha.

Land acquisition is complete, with 11.16 hectares in Kozhikode and 8.32 hectares in Wayanad secured. Compensation of Rs 3.8 million has been deposited in the state CAMPA account. The chief minister is expected to inaugurate the project in July.

The environmental clearance comes with over 60 strict conditions to mitigate ecological impact in the sensitive Western Ghats. Measures include vibration and landslide monitoring, regulated blasting, elephant corridor protection, safeguarding endangered species and wetlands, and construction of groundwater monitoring and wildlife underpasses.

Tunnel excavation will be preceded by an extensive geological survey to address groundwater seepage and slope stability, along with installation of sensors for landslide and vibration detection. The environmental clearance also mandates regular submission of compliance reports and monitoring for air quality and hydrological effects.

Proponents emphasise that the twin tunnel will bring reliable, all-weather connectivity, bolstering tourism, commerce, emergency services and regional growth. Critics, however, caution that the project traverses ecologically fragile terrain noted for past landslides in 2019 and 2024, urging adherence to safety protocols.

Once completed, the tunnel will not only improve travel between Kozhikode and Wayanad but also provide an important link for commuters travelling towards Bengaluru, Mysuru and Coorg, bypassing the hazardous Ghat road entirely.

The Kozhikode–Wayanad twin-tube tunnel project is set to commence construction following environmental approval from the Union Ministry of Environment, Forest and Climate Change. The Rs 21.34 billion (approx. USD 260 million) project aims to significantly improve connectivity between Kozhikode and Wayanad by bypassing the congested and landslide-prone Thamarassery Ghat section of NH 766.Stretching approximately 8.17 kilometres from Anakkampoyil in Kozhikode to Kalladi near Meppadi in Wayanad, the new route is expected to reduce travel distance by around 40 kilometres and cut journey time considerably.
