The long-awaited elevated highway in the 12.75-km-long Aroor-Thuravur National Highway 66 corridor is nearing completion, with the National Highways Authority of India (NHAI) completing 90% of work on the project.

Sources said the ₹2,200-crore elevated structure would in all probability be opened to motorists from August, if all works went ahead as planned. Once completed, it would be the longest such elevated highway supported by single pillars in the country. The NHAI had earlier set February 2026 as the deadline to complete the project.

“The launch of girders and the installation of deck slabs over them are over, except on a short stretch at Aroor where extra high-tension [EHT] power lines reportedly ought to be relocated. At present, the rest of the elevated structure is being painted, while work on the drains on either side is on.

The NHAI has issued a letter to the District Collector of Alappuzha, saying that it is willing to remit to local bodies the expense for constructing drains that will carry away water from the NH drains, to waterbodies on either side. A joint inspection was conducted recently, and an estimate is expected to be readied shortly,” the sources added.

The length of the elevated NH would, in the meantime, be increased by 210 metres southward from Thuravur. A dozen more pillars are being built as part of this, it is learnt.

The NHAI had earlier extended funds to the Public Works department to upgrade side roads in order to cater to traffic that was being diverted from the 13-km corridor where the elevated structure was being built, to the Kerala Water Authority to relocate drinking water pipelines from the NH, and to the Kerala State Electricity Board to relocate posts and transformers.
