Volvo graders have made an important contribution on upgrades to a 150km stretch of the NH7 highway, one of India's most important road links. The NH7 highway is an impressive 2,369km in length, linking the town of Kanyakumari, perched on the southern-most point of the Indian mainland where the Arabian Sea, Bay of Bengal and Indian Ocean meet, with the north-eastern holy city of Varanasi on the banks of the river Ganges.
