Golden Quadrilateral

The Golden Quadrilateral (GQ), launched in 2001 under the National Highways Development Project, is a 5,846 km expressway network connecting Delhi, Mumbai, Chennai, and Kolkata.

It enhances freight efficiency, reduces travel time by 25–40%, and fosters industrial growth along its route.

The GQ passes through key states including Haryana (Delhi–Ambala stretch), aiding logistics for Panipat’s textile and Karnal’s agro industries.

A NHAI report noted that GQ carries 40% of India’s freight traffic, making it a cornerstone of India’s economic integration.
