The Golden Quadrilateral is a highway network connecting India 's four largest metropolises: Delhi, Mumbai, Kolkata and Chennai, thus forming a quadrilateral of sorts. Four other cities among the top ten metropolises: Bangalore, Pune, Ahmedabad, and Surat, are also served by the network, which connects many of the major industrial, agricultural and cultural centres of India.
The largest highway project in India and the fifth longest in the world[citation needed], it is the first phase of the National Highways Development Project (NHDP), and consists of building 5,846 km (3,633 mi) four/six lane express highways at a cost of 60,000 crore (US$10.92 billion).[1]The four-lane system was constructed between 1999 and 2012, and is currently being expanded to six lanes throughout.
The vast majority of the Golden Quadrilateral (GQ) is not access controlled,
