Even as the government is hopeful of completing the widening of the 582-km stretch of National Highway-66 by the revised deadline of December 2025, the average progress of the work on the various stretches from Kasaragod to Thiruvananthapuram is around 41%, including the elevated highways.
Among the works on various reaches, those in northern Kerala are relatively faster than in central or southern Kerala.
The work on the six-laning of the stretch from Thalapady to Chengala has been completed by around 58.10% — the major stretch where the highest work progress has been made. On the other hand, the progress on the stretch between Thuravur to Paravoor in Alappuzha is 19.40%. The elevated corridor along with the development of the existing four-lane road from Aroor to Thuravoor has recorded a work progress of 13.33%, the lowest in the State.
