In 2021 February, the works on 15.7 km Reach-1 between Parassala - Kudappanamoodu was re-tendered since the contractor to whom it was awarded initially had died due to COVID-19 pandemic.
In Wayanad district as of February 2021, the land acquisition from tea estates on a 13 km stretch between Meppadi and Chooralmala is pending.
[19] This area is ecologically sensitive and was impacted severely by 2019 Kerala floods and approval from Forest Department is still pending in this stretch.
It will help boost tourism, improve connectivity and transportation, easy market access to farmers from the hilly regions, relief measures during disasters etc.
[21] Though there are apprehensions that this project has ecological impacts, the benefits and value that it brings to people living in high range areas is tremendous.
