The Delhi-Dausa-Lalsot section of the Delhi-Mumbai Expressway is the corridor that made India’s longest expressway real. Before February 12, 2023, the Delhi-Mumbai Expressway was a construction project of extraordinary scale but limited operational reality — sections under different stages of completion, tolls not yet collected, the public unable to drive what the government had been discussing since 2018. PM Modi changed that on February 12, 2023 when he dedicated the 246-kilometre Delhi-Dausa-Lalsot section to the nation — the first completed section of the 1,386-kilometre NE-4 corridor that will eventually connect the national capital to the financial capital.
The Delhi-Dausa section covers approximately 221 kilometres from Sohna (Haryana) to Dausa (Rajasthan), with the further Dausa-Lalsot stretch taking the operational corridor to 246 kilometres total. The section was built at a cost exceeding ₹12,150 crore. It made the Delhi-Jaipur journey possible in approximately 3.5 hours — down from the earlier 5 hours on NH-48 — a direct operational benefit immediately felt by the enormous travel volume on this corridor.
The Delhi end of this section originates at the Sohna Elevated Corridor — itself a 21.65-kilometre, six-lane access-controlled corridor from Rajiv Chowk in Gurugram to Sohna, opened July 11, 2022 — while the DND-Faridabad-KMP section (59 km) forms the additional Delhi-side connector. The combined length of operational sections as of May 2026 stands at approximately 82 to 94 percent of the total 1,386 km expressway.

Route and Location
The section starts at Sohna — Gurugram’s southern satellite town — and runs southwest through Haryana’s Alwar border zone, crosses into Rajasthan near Alwar, passes through the Aravalli hill country and the Bandikui-Dausa agricultural belt before ending at Dausa on the NH-48 Rajasthan corridor. The Bandikui-Jaipur spur (67 km) branches from the expressway to connect toward Jaipur city, making the expressway the practical fast road for Delhi-Jaipur travel.
Connectivity
The Sohna Elevated Corridor at the north feeds from Delhi’s DND Flyway. The KMP Expressway at Khalilpur provides additional Delhi-NCR access from the western and southern directions. At Dausa, NH-48 connects toward Jaipur’s city center, and the expressway continues southward through Sawai Madhopur and Kota toward Madhya Pradesh and Gujarat.
Nearby Areas
Alwar — the Rajput princely capital with the Siliserh Lake, Neemrana Fort Palace (one of India’s finest heritage hotels), and Sariska Tiger Reserve — is the primary heritage-tourism destination on the Delhi-Dausa section. Dausa district, where the section ends, is known for the Abhaneri stepwell — Chand Baori — one of the most photogenic ancient stepwells in Rajasthan.
