Explanation: The Golden Quadrilateral (GQ) is a strategic highway network in India that connects four major metropolitan cities: Delhi, Mumbai, Chennai, and Kolkata. This network forms a diamond-shaped route, hence the name "Quadrilateral," and is a critical part of India's national highway system. The GQ was designed to improve connectivity between these major cities, enhance economic growth, and facilitate the movement of goods and people across the country.
The four cities connected by the GQ are:
1. Delhi: The capital city of India, located in the northern part of the country.
2. Mumbai: A major port city and financial hub in the western part of India.
3. Chennai: An important industrial and commercial center in the southern part of India.
4. Kolkata: A significant port city and industrial center in the eastern part of India.
The GQ network is approximately 5,846 kilometers long and was completed in 2012. It is a four-lane highway that connects these four major cities, forming a loop that passes through several other important cities and towns along the way. The network is designed to reduce travel time and improve road safety, making it easier for people and goods to move between these major economic centers.
Bengaluru, also known as Bangalore, is a major city in South India and a significant economic and technological hub. However, it is not one of the four cities connected by the Golden Quadrilateral network. This is a common misconception, as Bengaluru is a major city and might be assumed to be part of such a significant highway network. However, the GQ was specifically designed to connect the four major metropolitan cities mentioned above, and Bengaluru is not included in this network.
Understanding the Golden Quadrilateral network is important for students of Indian geography and transportation infrastructure, as it highlights the strategic importance of these major cities and the role of highways in connecting them. It also provides insight into the economic and logistical considerations that go into the planning and development of such large-scale infrastructure projects in India.
