India has the third-largest road network in the world spanning 4.69 million km, next in line only to the US and China. However, when it comes to the quality of roads, India lags far behind. Compared to the length of expressways in leading countries, China (84,946 km), the US (75,238 km), Canada (17,000 km), Spain (15,152 km) and Germany (12,800 km), India’s progress in the road sector seems dwarfed at just 200 km.
On an overall basis also, highways constitute only a 1.7 per cent share at 79,116 km.
Given the importance of expressways, the Government of India had approved the construction of 1,000 km of expressways under the National Highways Development Project (NHDP) Phase VI.
Besides, the ministry came up with a project report to formulate a master plan aiming to construct 15,600 km by 2022, marking the end of the 13th five year plan.
