[4] Nitin Gadkari, the Minister of Road Transport and Highways announced the opening of one of the twin tube tunnels through the social platform Twitter.

[7] In October 2020, a Gridlock happened after an accident causing long queues extending to kilometers on both sides, and traffic resumed only in the evening after temporarily opening the under construction tunnel.

These type of gridlocks used to happen regularly at this spot due to frequent accidents, and people who are aware of this used to prefer alternative longer routes just for the sake of a reliable journey time.

[9] In January 2020, the tunnel was partially opened to facilitate Power Grid Corporation of India's underground cabling works between Thrissur and Palakkad.

[10] On July 31, 2021, one of the two tunnels in Palakkad - Thrissur direction was officially opened for traffic following an announcement made by Nitin Gadkari through Twitter.
