Delhi Mumbai Expressway
In short
This 1,350-kilometre eight-lane highway connects India's capital, New Delhi, to its financial hub, Mumbai. It significantly reduces travel time between the two cities from 24 hours to approximately 12 hours.
In plain words
It is a massive new road built from scratch to make driving between Delhi and Mumbai much faster. It uses special controlled access to keep traffic moving smoothly through several Indian states.
A simple example
A driver travelling from Delhi to Mumbai can now complete the journey in half the time it used to take using older routes.
Why it matters
The expressway speeds up the movement of goods and people across India's most important economic corridor. It helps lower transport costs and boosts trade between the north and west of the country.
Easy to mix up
Do not confuse this with the existing National Highways that connect the same cities via longer, slower routes.
