NH 544 Stability Assessed Following Mudslips Near Kuthiran Twin Tunnels
State officials and NHAI engineers launched an inspection after monsoon rains triggered soil displacement above the strategic Kochi-Salem highway link. While debris remains trapped between rock faces, authorities are monitoring the site to ensure the structural integrity of the tunnels.
Key takeaways
- Minor mudslips occurred above the Kuthiran twin tunnels on NH 544 following heavy monsoon rains.
- Structural assessments by NHAI and the Forest Department found no immediate threat to the highway or tunnel stability.
- Debris remains trapped in rock faces above the portal, ensuring that traffic flow between Kochi and Salem is not restricted.
Emergency Site Inspection Conducted
Intense monsoon rainfall triggered two minor mudslips above the Kuthiran twin tunnels on National Highway 544 this Friday. The incidents occurred over the central section of the passage, situated between the entrance and exit portals. District Collector Shikha Surendran and MLA K. Rajan led a joint delegation of National Highways Authority of India (NHAI) and Forest Department officials to the site to evaluate potential hazards to the critical infrastructure.
Current Status and Traffic Safety
Despite the displacement of soil, authorities confirmed that vehicular movement on the Kochi-Salem National Highway continues without interruption. MLA K. Rajan stated that the dislodged debris did not reach the road surface, as it remains caught within rock crevices located directly above the tunnel structures. Engineers from the NHAI are currently analyzing the area, though they have determined there is no immediate threat to the tunnel's physical composition or the safety of commuters.
Stability Assessments and Next Steps
A comprehensive evaluation of the slope is planned to identify the root cause of the soil movement. District Collector Shikha Surendran noted that a joint team from the NHAI and the Forest Department will climb to the upper reaches of the terrain to inspect for water accumulation or seepage. This high-altitude survey is necessary to determine if the saturated soil poses a long-term risk to the slope's stability. Officials emphasized that precautionary monitoring will persist throughout the remainder of the monsoon season to prevent sudden disruptions on this high-traffic corridor.
Key Facts
- Two minor mudslips were identified on the western side of the Kuthiran twin tunnels on August 7, 2026.
- The displaced soil is currently lodged between rocks above the tunnel portals rather than on the highway.
- Traffic flow on NH 544 remains unaffected by the incident.
- A joint technical team including Forest Department personnel will conduct an aerial or high-slope inspection to check for seepage.
