The Golden Quadrilateral Highway is one of the largest road development projects in India. It was launched under the National Highways Development Project (NHDP) to improve road connectivity between the four major metro cities: Delhi, Mumbai, Chennai, and Kolkata. Covering a length of about 5,846 kilometers, it facilitates smooth transportation of goods and passengers, reduces travel time, and boosts economic activities by connecting major industrial, agricultural, and cultural centers. This project has significantly contributed to the country’s infrastructure growth, making trade and commerce more efficient.
