NH 66

National Highway 66, commonly referred to as NH 66, is currently being developed into a 10-lane, including two-lane service roads on either side by the NHAI.

The stretch will be developed as per the standards of Indian Road Congress and will be constructed on Engineering, Procurement, Construction (EPC) model.

Progress Made

Kadampattukonam – Kazhakootam

RDS Project Limited, currently handling the Kazhakkoottam elevated highway project, has won the bid to develop a 29-km stretch of National Highway 66 from Kazhakkoottam to Kadampattukonam in Parippally.


Work completed.


The Mukkola- Karode NH 66 bypass stretch and elevated highway at Kazhakootam is likely to be commissioned in August 2022. The National Highways Authority of India (NHAI) is planning to execute the work in such a way that both roads can be opened to public simultaneously in August.


The new alignment of the Vazhimukku-Kaliyikkavila stretch, which will be developed into a six-lane highway is expected to be published soon. According to officials, the Kerala Infrastructure Investment Fund Board (KIIFB) has already begun the LiDAR ( Light Detection and Ranging) survey to identify the curves on the 18km stretch.

Kanyakumari NH 66

There is very little progress on the stretch between Karode and Kanyakumari. NHAI is planning to foreclose the contracts due to the unavailability of red earth and land acquisition hurdles. The Trivandrum Chamber of Commerce and Industry (TCCI) has raised the issue before the Kerala and Tamilnadu MPs as well as with the Tamil Nadu Chief Minister.
