The 8-lane, access-controlled Delhi-Mumbai Expressway (DME) project, which spans 1350 kilometres and connects DND in Delhi with JNPT in Mumbai, is currently under construction.
It has been planned with a 120 km/h speed restriction with the option to add 12 lanes later.
Five states—Haryana (80 km), Rajasthan (380 km), Madhya Pradesh (370 km), Gujarat (300 km), and Maharashtra—will be connected by the motorway with closed tolling (120 km).
Along its path, new industrial townships and Smart Cities have been planned. On either side, 92 wayside facilities have been proposed at intervals of around 50 kilometres.
Due to its alignment, Delhi and Mumbai are now only 150 km apart, cutting the existing 24-hour travel time in half to 13 hours.
In addition, compared to the current NH-48 (old NH-8) highway, the motorway will result in significant fuel savings, better ride quality, and increased safety.
It will link towns like Ratlam, Mandsaur, and Jhabua in Madhya Pradesh.
The highway would pass through towns including Dausa, Tonk, Bundi, Kota, Bharatpur, and Alwar in Rajasthan.
The express will only be allowed to go at a top speed of 120 km/h.
The most recent photo of the section of the Delhi-Mumbai Expressway between Khanpur Ghati and the Haryana/Rajasthan border was recently shared by Union Minister Nitin Gadkari.
By December 2023, the Delhi–Mumbai Expressway project should be finished.
