India’s 11 Super Expressways

India, a developing country has world’s third largest road network but when we talk about expressways, we can hardly name a few like Mumbai-Pune Expressway and Delhi-Gurgaon Expressway. So we decided to tell you about some of the other expressways in India.

Here is the list of India’s top 11 Super Expressways

1) Ahmedabad Vadodara Expressway
Ahmedabad Vadodara Expressway is 95 km long and joins Ahmedabad and Baroda in Gujarat. It is also referred as National Expressway 1. This expressway was opened to public in 2004 and was constructed under the Golden Quadrilateral Project by NHAI.

Mumbai-Pune Expressway (official name is the Yashwantrao Chavan Expressway) is 93 km long and is considered as one of the best expressways in India. It is India’s first six lane high speed expressway and was made by Maharashtra State Road Development Corporation (MSRDC) at a staggering cost of Rs 1,630 crore (US$363.49 million). It was opened to public in April 2002

3) Jaipur-Kishangarh Expressway
Jaipur-Kishangarh Expressway is 90km long and it connects Jaipur with Kishangarh. It was constructed under the Golden Quadrilateral National Highways Development Project and its cost was USD 154 million. More than 20,000 vehicles pass from this highway everyday.

7) Delhi-Gurgaon Expressway
Delhi-Gurgaon Expressway covers a distance of 28 km and has been a life saver for commuters. Before construction of this expressway huge traffic jams were seen on the roads. Though this problem has not been solved 100% but still this expressway has brought some relief to the commuters. Delhi-Gurgaon Expressway starts at Dhaula Kuan in Delhi and ends at Manesar which is on the outskirts of Gurgaon. The cost of this project was $223 million and it was opened for public use in January 2008.

8 ) Noida-Greater Noida Expressway

9) Delhi Noida Direct Flyway
Delhi Noida Direct Flyway or popularly known as the DND flyway is an eight lane road having a total length of 9.2 km and connects Delhi to Noida. It was built by The Noida Toll Bridge Company Ltd.

10) Hyderabad elevated expressway
Two separate elevated expressways were to be constructed in Hyderabad to overcome the congestion problem. The first one is P.V. Narasimha Rao Elevated Expressway which covers a distance of 11.6 km and the other Rajiv Elevated Expressway which will cover the distance of 20 km. P.V. Narasimha Rao Elevated Expressway was completed in 2009 and it connects Hyderabad International Airport to Mehdipatnam. Rajiv Elevated Expressway was proposed as an extension and will cover Secunderabad-Shamirpet stretch via Karkhana, Trimulgherry and Bollarum. But this project is currently under suspension due to high project costs.

11) Hosur Road Elevated Expressway
Hosur Road Elevated Expressway covers a distance of 9.98 km and connects Bangalore to Hosur. This expressway has the distinction of becoming the tallest expressway in Bangalore at the height of 17 meters i.e. 56 ft. This project was started in 2006 by BETL and was inaugurated on 22 January 2010.

We have many more expressways in India which are under construction or are already approved but work has not started yet. But still India needs many more of those expressways, to reduce the traveling time and for better connectivity across other Indian cities and states.

World’s Highest Railway Bridge To be Built In India

With aspiration of becoming a global superpower, India’s construction industry is now thinking beyond the box.
