Explanations:The Golden Quadrilateral is a significant road development project in India that connects four major metropolitan cities: Delhi, Mumbai, Chennai, and Kolkata. This project is part of the National Highways Development Project (NHDP) and is designed to improve the connectivity and economic development of the country by providing a high-quality road network.
The Golden Quadrilateral is a 5,846-kilometer-long highway network that forms a quadrilateral shape connecting these four major cities. The project was initiated in 2001 and was completed in 2012. It is one of the largest highway projects in the world and has had a significant impact on the transportation and economic landscape of India.
The project aims to reduce travel time, improve road safety, and facilitate the movement of goods and people across the country. It has also helped to boost the economy by improving the efficiency of transportation and reducing logistics costs. The Golden Quadrilateral is a key component of India's infrastructure development strategy and has played a crucial role in the country's economic growth.
Other options such as linking Delhi and Amritsar, Varanasi and Kanyakumari, or Sri Nagar and Kanyakumari are not part of the Golden Quadrilateral project. These are regional roads that do not have the same scale or strategic importance as the Golden Quadrilateral. The Golden Quadrilateral is a national project that connects the four major metropolitan cities, making it a significant development in the country's infrastructure.
