The Golden Quadrilateral (GQ) is a national highway network connecting most of the major industrial, agricultural and cultural centres of India. It forms a quadrilateral connecting the four major metro cities of India, viz., Delhi (north), Kolkata (east), Mumbai (west) and Chennai (south). Other cities connected by this network include Ahmedabad, Bengaluru, Balasore, Bhubaneswar, Cuttack, Durgapur, Jaipur, Kanpur, Pune, Kolhapur, Surat, Vijayawada, Ajmer, Vizag, Bodhgaya, Varanasi, Allahabad, Agra, Mathura, Dhanbad, Gandhinagar, Udaipur, and Vadodara. The main objective of these super highways is to reduce the distance and time between the four mega cities of India.
