In addition, a new road link to NH 66 has been completed between Thaikkad and Vettu road (near Kazhakootam in Trivandrum). In phase 2, the Chengannur – Ettumanoor 47 km (29 mi) stretch was upgraded. The road has a total width of 10 metres (33 ft) and facilitates two-lane traffic. The road also have a 7-metre (23 ft) carriageway and a sealed shoulder, having width of 1.5 metres (4 ft 11 in).
