Besides operating the infrastructure until 2027, Isolux Corsán, in consortium with the local company Soma, has carried out the works to extend and improve the road.
The NH8, with a length of 94 km, has been widened from 2 to 6 lanes each way. Also standing out as main structures in this route, there are 3 railroad bridges and 6 viaducts. With the beginning of operation of the NH8, the company, through its subsidiary Isolux Infrastructure, consolidates its activity in India with the management of four toll roads in the country, which add up to a total of over 710 km.
The project has been developed on a design, build, finance, operation and maintenance (DBFOM) basis for a period of 18 years.
The total project investment is estimated at Rs13 billion (US$204.4 million)
Besides the NH8, the company has the concession of the NH1, NH2 (Varansai-Aurangab) and NH6 (Maharashtra/Gujarat-Hazira Port ) toll roads, 291, 192 and 133 km long respectively. The latter has a concession period of 18 years. In all of them, Isolux Corsán is in charge of the extension and improvement of the existing road.
In the case of NH1, the highway under construction and operation, Isolux Corsán has widened from 4 to 6 lanes each way, added service roads to both sides as well as built more than 150 structures (viaducts, overpasses, underpasses, etc.)
The NH2 is under construction phase with an extension from 4 to 6 lanes each way, service roads and more than 75 structures (viaducts, railroad crossings, overpasses, underpasses, etc.)
