Last year the NHAI set a new record by laying down a 75 kilometre highway between Amravati and Akola in just 105 hours and 33 minutes. The construction speed of highways in India has also surged by more than 300 per cent in just seven years. But the Road Transport Ministry has plans to accelerate this further, as Minister of State VK Singh has said that prefabricated material will be used to build highways at a faster pace.
