Sorry for my ignorance. But where is this Karamana-Kaliyikkavila highway and why is it not getting widened to 45 meters?
is a stretch in that part of old NH 47 which connects Trivandrum with Kanyakumari.
Karamana is a major junction of Trivandrum city. Kaliyikkavila is the state border, about 31 kms from Trivandrum.
Within Trivandrum city, infact the four laning had been completed till 'Neeramankara', about 1 km further from Karamana perhaps more than 5 years back.
This stretch would be one of the oldest roads in Kerala, dating back to the 17th century. Travancore State Transport Department (Now KSRTC) had started plying buses imported from UK from 1930s or so. The road was then a concrete one. It was a vital link in the civilisation of this region.
Now this stretch passes through the densely populated areas of Trivandrum City and Trivandrum Capital Region. Its like a continous urban area hence the demolitions/acquisitions would be more and hence width kept at 30.2 metre and the Bypass is there with 45m.
combined bypass will help motorists to take deviation at the northern entrance of Trivandrum Corporation at Kazhakuttom and then exit through the southern end of Kovalam/Vizhinjam and get in to TN. The highway till Kovalam is ready from the last decade.
