THIRUVANANTHAPURAM: The much-touted six-laning work of 29-km NH-66 stretch from Kazhakootam to Kadampattukonam, on the Kollam-Thiruvananthapuram border, will be delayed due to legal hurdles in acquiring land for constructing a bypass at Attingal and the inordinate delay in receiving the estimate from KSEB for shifting its utilities. As a result, the tender for selecting the contractor for the project could be floated only after two months. Earlier, the National Highways Authority of India (NHAI) had planned to start the widening of the road from April after floating tenders in February this year. But nothing has happened.
