World’s Longest Highway: ( Delhi- Mumbai Expressway) GS- 3 – Infrastructure


Nitin Gadkari (Union Minister for Road Transport and Highways) recently concluded the two-day review of the work progress on eight-lane Delhi-Mumbai Expressway, which will reduce travel time between certain cities to 12-12.5 hours from 24 hours.  It will be the world’s longest highway once completed covering a total distance of 1380km. It is expected to be completed by March 2023. It will connect Haryana’s Sohna and Mira Bhayander near Mumbai. The highway project was  started in the year 2018 with the project’s foundation stone being laid on 9 March 2019. 



  • It will be equipped with onside amenities like resorts, restaurants, first aid, food courts, fuel stations, facilities for truckers, and logistics parks.

  • An Emergency helicopter ambulance service for accident victims and a heliport, which will use drone services for business activities as well.

  • The expressway is the first in Asia and only the second in the world to feature animal overpasses (Animal Corridors) to facilitate unrestricted movement of wildlife.

  • It will also include two world class 8-lane tunnels, one tunneling through Mukundra sanctuary, Rajasthan and the second will pass through the Matheran eco-sensitive zone, Maharashtra.

  • The expressway will result in a fuel savings of more than 320 million litres annually and reduce CO2 emissions by 850 million kg which is equivalent to the planting of 40 million trees.

  • The entire expressway is being constructed keeping in mind the environment-friendly expressway with a tree cover of 2 million trees. They are being watered with drip irrigation along the entire stretch with a rainwater harvesting system at every 500 metres. 

  • More than 12 lakh tonnes of steel will be consumed in the construction of the expressway, which is equivalent to building 50 Howrah bridges.

  • 80 lakh tonnes of cement will be used for the project, which is around 2% of countries annual cement production capacity.

  • The project has also created employment for thousands of trained civil engineers and more than 50 lakh man days of work.

  • Once ready, the expressway will feature a spur to Noida International Airport and Jawaharlal Nehru Port to Mumbai through a spur in the financial capital.


  • The connectivity of India’s capital with its financial capital will improve connectivity of other economic hubs like Jaipur, Kishangarh, Ajmer, Kota, Chittorgarh, Udaipur, Bhopal, Ujjain, Indore, Ahmedabad, Vadodara and Surat. 

  • It will give a boost to other such projects across the country thereby leading to overall development.
