Ending the questions and concerns about its opening, the Kuthiran Tunnel has finally become accessible to vehicles on 31 July 2021. In an anti-climax that has obviously upset the state govt, the central govt announced the opening of the tunnel dramatically. Out of the two tunnels, the left tunnel from Palakad to Thrissur is the one that has become functional now.
The twin tunnels have been set up in Kuthiran to ensure the optimal utilization of the six-lane path from Mannuthy in Thrissur to Vadakkanchery in Palakkad. For a six-lane road to be constructed in Kuthiran instead of the tunnel, almost four hectares of forest land was required. This was another reason for the tunnel. The budget for the project stood at 200 crores. It is owned and operated by the National Highways Authority of India and is Kerala's first-ever tunnel for road transport and South India's Longest 6-lane road tunnel. It is also the only twin tunnel on the South Indian highway.
The vehicles coming from Palakkad can be let through the first tunnel. The alternative for the existing path is about 3kms. The tunnel that is 965 meters in distance will increase the traffic network significantly. The vehicles can cross the area within two minutes. The traffic block in Kuthiran can be easily solved.
