About
The Delhi-Mumbai Expressway is India's longest expressway under construction — a 1,380 km eight-lane access-controlled corridor connecting Delhi NCR to Mumbai across five states (Haryana, Rajasthan, Madhya Pradesh, Gujarat, Maharashtra). Sanctioned in 2018 and being delivered in 52 packages by NHAI, the expressway will reduce Delhi-Mumbai road travel from 24 hours to 12.
The alignment cuts a fresh corridor through largely undeveloped land — bypassing both the Mumbai-Agra (NH-3) and Delhi-Mumbai-via-Vadodara (NH-48) routes. Phases opened so far (as of late 2024) include Sohna-Dausa (Haryana-Rajasthan), Dausa-Bharatpur, and Vadodara-Mumbai sections, totalling ~600 km.
The expressway features two major tunnels: one 4 km tunnel through the Mukundra Hills wildlife sanctuary in Rajasthan, and a 2 km tunnel through the Western Ghats near Khopoli. The Khopoli-Karjat segment includes ~52 km of viaduct over difficult terrain. Total project cost: ₹98,000 crore.
Design features include 12-lane provision (currently 8 + 4 future), 100-km/h design speed across all sections, integrated electric-vehicle charging plazas every 50 km, and provisioning for future autonomous-vehicle infrastructure. The expressway is also designed with helipads at key emergency points for medical evacuation in remote stretches.
Full commissioning is targeted for late 2026.
