February 12, 2023 is a date in India’s expressway calendar. On that day, Prime Minister Modi inaugurated the Sohna-Dausa section of the Delhi-Mumbai Expressway — the first stretch of what would eventually become India’s longest expressway to open for public use. The 221-kilometre stretch connecting Sohna in Haryana to Dausa in Rajasthan was not merely a road opening. It was the tangible demonstration that the Delhi-Mumbai Expressway — a 1,386-kilometre, eight-lane project crossing six states and reducing Delhi-Mumbai travel from 24 hours to 12 — was graduating from construction site to operational reality.
The Sohna-Dausa section begins at Sohna in Haryana’s Gurugram district — where the Sohna Elevated Corridor (21.65 km, operational since July 11, 2022) feeds traffic southward from Delhi’s DND Flyway and the Gurugram arterial network — and runs southwestward through Alwar, Bandikui, and Dausa in Rajasthan at a design speed of 120 km/h. The section covers 221 kilometres of the expressway’s main 844-kilometre Sohna-Vadodara stretch, passing through Haryana’s 70-kilometre section and Rajasthan’s 151-kilometre initial section. Toll collection began on February 14-15, 2023. The section is the gateway to the Delhi-Mumbai Expressway’s promise — no signals, no at-grade crossings, 5G digital infrastructure, helipads at 100-kilometre intervals, and trauma centres at 100-kilometre intervals.
The Dausa-Sawai Madhopur section opened October 2, 2023, extending the accessible portion further. Multiple other sections have opened progressively since. As of May 2026, the expressway is approximately 82 to 94 percent complete — with the final DND-Delhi section and certain Gujarat-Maharashtra stretches representing remaining work.

Route and Location
The Sohna-Dausa section runs from Sohna — the southern Gurugram sub-city — southwestward through the Aravalli foothills of Haryana, crosses into Rajasthan near Alwar, and continues through Alwar and Bandikui districts to Dausa, which sits on the NH-48 Delhi-Jaipur highway. The terrain transitions from Haryana’s flat agricultural land to the Aravalli hill country of Rajasthan — giving the expressway’s first section a scenic character absent from many expressway corridors.
Connectivity
The Sohna Elevated Corridor connects to Delhi’s DND Flyway at the north, and the KMP Expressway at Khalilpur in Nuh district connects to the south — giving the Sohna-Dausa section access to Delhi’s full NCR orbital ring. At Bandikui, the 67-kilometre Jaipur Spur connects directly to Jaipur. Dausa is on NH-48, connecting toward Jaipur’s city center and westward.
Nearby Areas
Alwar — the Rajput princely state capital with its imposing hill fort, the Siliserh Lake, and the Sariska Tiger Reserve — is on the Sohna-Dausa section’s Rajasthan stretch. Neemrana Fort Palace, one of the most celebrated heritage hotels in North India, is accessible from the expressway’s approach zone. Bandikui, the rail junction town, provides the expressway with its Jaipur connectivity point.
