Ashoka Buildcon, a company based in Maharashtra, is in charge of the construction. A six-lane road will be constructed above the single pillars that will be constructed in the median. A total of 373 pillars are required for the flyover. Each pillar is erected on top of pile foundations, which are dug into the ground and constructed using wire and concrete. The pillars are poured on top of the pile cap which is prepared by joining eight piles which are constructed at a distance of one quarter meter. In this way the piles for constructing 35 pillars are ready. Five of these pillars have reached the stage of concreting.
Depending on the soil texture and the capacity of the flyover, the piles are excavated at a depth of 55 to 65 m. For this, ten machines are working in the region. Most of the flyover pylons are 9.5 meters high. Place girders above these. The skyway above the pillars will be 24 meters wide. The project costing 1668.5 crores is proposed to be completed within three years.
From Kasaragod to Kanyakumari, construction work is currently underway to widen the national highway into six lanes. The private land on both sides of the road has been acquired and the construction is 45 meters. However, land acquisition was not easy in Arur-Thuravur section, which is currently four lanes wide. The National Highway Authority decided to construct the skyway in view of the high cost of land and the abundance of buildings in this region adjacent to the city of Kochi. Once the six-lane main road is ready above, the current four-lane service road will be converted. Local residents can use the lower lane for short trips.
The flyover starts from near Arur Palli and extends to the south of Thuravoor. In between there will be ramps to go down at Chantirur and Kuthiyathod. There will also be a facility to go down to Toppumpadi in Arur. A toll plaza is also being constructed at Eramallur for the passengers of the flyover. Meanwhile, there is a plan to build a flyover from Arur to Edapally as a continuation of this. Its study is ongoing.
