Delhi-Mumbai Expressway: India's Longest Road Is Almost Done — What It Means for Drivers

India's Delhi-Mumbai Expressway, the country's longest road project and the world's longest access-controlled highway upon completion, is approaching its final phase. When the last section opens in November 2026, drivers will be able to cover the 1,362 km between India's capital and its financial capital in approximately 12 hours — half the time the older NH48 route demands. Built by the National Highways Authority of India (NHAI) under the Bharatmala Pariyojana Phase 1 programme, the expressway passes through six states, has a design speed of 120 km/h, and introduces barrier-free Multi-Lane Free Flow tolling on its newest sections. This article covers the full picture: route, current status, toll structure, what opens where, and what all of it means for used car buyers and sellers along this corridor.

Route: Six States, One Corridor

The Delhi-Mumbai Expressway runs from Dwarka in Delhi to Bhiwandi on the outskirts of Mumbai, passing through Haryana, Rajasthan, Madhya Pradesh, Gujarat, and Maharashtra. The alignment follows a broadly western path that avoids the congested NH48 (old National Highway 8) corridor through cities like Gurugram, Jaipur, and Kota. Instead, the new expressway takes a more direct greenfield route that cuts distance and, crucially, bypasses urban congestion entirely through access-controlled design.

The six-state journey connects a remarkable range of Indian cities. Starting in Delhi, the expressway passes through Haryana before entering Rajasthan via the Alwar region. It crosses Rajasthan's industrial corridor, touching the periphery of Dausa and Sawai Madhopur, before entering Madhya Pradesh near Kota. Through MP, the expressway passes close to Shivpuri and Guna. It then enters Gujarat near Vadodara before heading south through Surat and crossing into Maharashtra. The final stretch traverses Nashik's approach roads before arriving at Bhiwandi, Mumbai's logistics hub.

Beyond the main corridor, the expressway includes several spur roads and connectors that link major cities directly to the expressway without requiring them to be on the primary alignment. Jaipur, the state capital of Rajasthan, connects via a dedicated spur. Vadodara and Surat in Gujarat each have direct interchange connections. A connector near the MP stretch links to the outskirts of Bhopal. These spurs effectively extend the expressway's economic reach significantly beyond the 1,362 km main alignment, making it a backbone infrastructure project rather than a point-to-point road.

Current Status: What Is Open, What Is Under Construction

Construction on the Delhi-Mumbai Expressway has proceeded in packages, with different sections opening at different times. As of mid-2026, multiple sections are already open and in use by the public, while the remaining sections are in the final stages of construction with completion targeted for November 2026.

The sections that are already operational include several stretches in Haryana and parts of Rajasthan that opened earlier in 2025 and early 2026. Drivers who have used these open sections report the road surface quality as excellent — wide lanes, smooth tarmac, good signage, and well-lit stretches through the night. The barrier-free MLFF tolling on newly commissioned sections means there are no toll plazas to slow down; vehicles are scanned as they pass through the expressway and tolls are deducted from FASTag accounts automatically.

The remaining sections — primarily in Madhya Pradesh, the Gujarat-Maharashtra border zone, and the final approach to Mumbai — are on track for completion by November 2026. NHAI has maintained construction activity through the 2026 summer, with work progressing on bridges, interchanges, and the expressway's pavement layers. The Bhiwandi terminus near Mumbai, which connects the expressway to the Mumbai Metropolitan Region's road network, is one of the more complex engineering segments due to terrain and urban interfaces, but it remains on the November schedule.

Travel Time and Fuel Savings: The Real Numbers

The headline claim — that the expressway cuts Delhi-Mumbai travel time from ~24 hours to ~12 hours — warrants closer examination. The 24-hour estimate for the old NH48 route accounts for real-world conditions: town crossings, traffic signals at hundreds of junctions, truck convoys near Surat and Vadodara, and the notorious congestion entering Mumbai via Thane and Bhiwandi on the old route. It is not an edge case — it is the typical experience for a driver covering the old route in normal traffic.

The 12-hour estimate on the new expressway is based on a sustained average speed of approximately 100-110 km/h on the 1,362 km corridor, accounting for two meal and fuel stops of around 20-30 minutes each. The expressway's design speed of 120 km/h — the highest in India — means that vehicles can legally travel significantly faster than on any other national highway. Most passenger cars will comfortably cruise at 100-110 km/h with engine load well within comfortable limits, yielding fuel economy close to their highway testing figures.

On fuel savings, the expressway offers a meaningful improvement through two mechanisms. First, the shorter route of 1,362 km versus the old highway's approximately 1,420 km saves around 60 km in distance. Second, and more significantly, sustained high-speed driving on a smooth access-controlled road is considerably more fuel-efficient than the stop-start rhythm of the old highway. Constant braking and acceleration at town crossings, the low-speed crawl through congested stretches, and the gear-hunting that comes with varying road quality all consume excess fuel. On the expressway, a vehicle cruises in top gear at a consistent speed, which is where most modern engines deliver their best efficiency. Estimates suggest a saving of 3-4 litres per trip compared to the old route — worth Rs 300-400 per trip at current fuel prices.

Key Exits, Interchanges, and Access Points

With 50+ exits across the 1,362 km expressway, drivers have abundant access points for fuel, food, overnight stays, and connecting to cities off the main alignment. The exits are spaced at practical intervals — typically 20-35 km apart in areas near towns, and up to 50-60 km apart through less-populated stretches. This spacing ensures drivers are never far from an exit if they need one, while keeping the number of access disruptions to the main carriageway low.

In Rajasthan, notable exits include those near Dausa (for tourists visiting Abhaneri stepwell), Sawai Madhopur (for Ranthambore National Park), and the broader Kota industrial region. The Jaipur spur connector is one of the expressway's most commercially significant links — it gives Rajasthan's capital of over 35 lakh people direct, high-speed access to the Delhi-Mumbai corridor. In Rajasthan's southern section, exits near Chittorgarh connect to Udaipur, making the Rajasthan tourism circuit significantly more accessible by road.

In Gujarat, the Vadodara interchange is a major node. Vadodara is one of Gujarat's largest industrial cities, and the expressway interchange here creates a direct link between the state's manufacturing heartland and both Delhi and Mumbai. The Surat stretch, passing near India's diamond-cutting and textile industries, includes multiple exits that serve the city's dense industrial zones. For car buyers, Surat and Vadodara represent large secondary markets where used car supply has historically been constrained by limited highway connectivity to the larger Delhi and Mumbai markets.

Toll Structure: MLFF, FASTag, and What to Expect

Toll collection on the Delhi-Mumbai Expressway varies by section based on when it was built and commissioned. Older sections use conventional FASTag-enabled toll plazas. The newer sections — particularly those commissioned in 2025 and 2026 — use Multi-Lane Free Flow (MLFF) barrier-free tolling, the same technology being rolled out across NHAI's newest projects. MLFF is discussed in detail in our earlier report on the Delhi-Dehradun Expressway, which also uses this system.

Under MLFF, there are no physical barriers and no need to slow down or stop. Overhead gantries installed across the carriageway read your FASTag transponder as your vehicle passes beneath them. The toll amount is deducted automatically from your linked bank account. There is no option to pay by cash or UPI at these points — it is strictly FASTag-based. This follows the broader policy direction from NHAI and the Ministry of Road Transport and Highways, which mandated FASTag-only tolls across national highways. Note that NHAI revised toll rates by 5% from April 1, 2026, so budgeting based on older rate charts will underestimate actual costs.

Final toll rates for the complete Delhi-Mumbai Expressway corridor have not been officially announced as of May 2026, as the project is not yet complete. Provisional rates on open sections are in line with NHAI's per-km rate structure for access-controlled expressways. For a rough estimate: NHAI's standard rate for cars on access-controlled highways is approximately Rs 2.00-2.50 per km. On 1,362 km, this would imply a one-way toll in the range of Rs 2,700-3,400 for a car. However, tolls are typically charged only on sections where a toll plaza or MLFF gantry exists, and not all portions of the corridor will have equivalent toll density. NHAI is expected to announce a consolidated toll schedule once the full corridor opens in November 2026.

India's Expressway Network in 2026: The Bigger Picture

The Delhi-Mumbai Expressway does not exist in isolation. India's expressway construction programme is in full stride in 2026, with a total of 7,332 km of access-controlled highway already completed and another 11,127 km under construction. The government's long-term target under Vision 2047 is 50,000 km of access-controlled highways — a near-sevenfold increase from current completed levels.

Several other major expressways have opened or are approaching completion alongside the Delhi-Mumbai corridor. The Delhi-Dehradun Expressway opened on April 14, 2026, cutting travel time from 6.5 hours to 2.5 hours on the 210 km route. The Ganga Expressway connects Meerut to Prayagraj over 594 km, opening up eastern Uttar Pradesh to high-speed travel. The Amritsar-Jamnagar Expressway and the Bengaluru-Chennai Expressway are both in advanced stages of construction, with completion targeted through 2026-2027. When complete, these expressways together will form a lattice of high-speed corridors connecting the major economic zones of the country.

India's expressway vision to 2047 is ambitious by any global standard. To put it in context, the United States built its 77,000 km Interstate Highway System over roughly five decades starting in the late 1950s. India intends to build approximately 50,000 km of comparable infrastructure in roughly two decades, driven by demand from a rapidly growing middle class and the logistics requirements of a manufacturing economy targeting global competitiveness. The Delhi-Mumbai Expressway, as the longest single project in this programme, is emblematic of this ambition.

What This Means for Used Car Buyers and Sellers

For anyone buying or selling a used car in the cities along this corridor — Delhi, Jaipur, Vadodara, Surat, Mumbai, or any of the dozens of secondary cities with expressway exits — the implications are concrete and near-term.

Expanded buyer-seller geography. Before the expressway, a used car seller in Delhi could realistically expect buyers from Delhi NCR and perhaps Haryana. The expressway changes the calculus significantly. A buyer in Vadodara or Surat can now make a day trip to Delhi for car inspection and drive it back, or purchase from a verified listing online and arrange transport. Similarly, a used car seller in Mumbai now has potential buyers from across Rajasthan, MP, and Gujarat who can access the Mumbai market in half a day. For VahanBazaar sellers, this means your listing reaches a far larger audience of genuine buyers who can act on it.

Highway-ready features command a premium. The expressway culture that has been building in India with projects like the Yamuna Expressway, Lucknow-Agra Expressway, and Purvanchal Expressway is now going national. Buyers who plan to use the Delhi-Mumbai corridor regularly — and there will be many — place serious weight on features that matter at 100-110 km/h. Automatic transmission eliminates fatigue on a 12-hour drive. Cruise control — even basic speed-hold cruise without adaptive functionality — makes a material difference to driver fatigue and fuel consumption on long stretches. Good NVH (noise, vibration, harshness) characteristics at highway speeds matter more than city driveability for this use case. In the used car market, these features are worth paying for, and sellers with highway-capable cars should highlight them in their listings.

Specific models to watch. For buyers looking for a highway-ready used car suited to regular expressway travel, the following models consistently score well in the combination of highway ride comfort, efficiency, features, and reliability: Hyundai Creta (2020 onwards), Kia Seltos (2019 onwards), Tata Harrier (2019 onwards), Honda City (2014-2019 generation and 2020 generation), Maruti Suzuki Grand Vitara, Skoda Octavia (for those wanting a larger sedan), and Toyota Fortuner for those prioritising space and commanding road presence. The Creta and Seltos in automatic variants with cruise control are particularly good value in the Rs 8 Lakh-14 Lakh used car range. The Harrier's large, stable wheelbase delivers notably composed highway ride quality at speed.

Pre-purchase checks for expressway use. If you are buying a used car specifically intended for regular Delhi-Mumbai expressway runs, the inspection checklist differs from a city car. At highway speeds, tyres and suspension absorb forces far beyond what city driving demands. Insist on a test drive that includes a sustained stretch at 80-100 km/h. Listen for tyre hum that indicates uneven wear or balancing issues. Feel for any steering pull or vibration above 80 km/h — this indicates wheel alignment problems or worn suspension components. Check that the air conditioning operates effectively under sustained highway load, not just during the dealer's demo. And verify that the engine oil and coolant are within specification — sustained high-speed running is far more thermally demanding than city driving. Our guide to expressway etiquette and preparation in India covers these checks and driving practices in full detail.

Logistics and freight implications for used car transport. Beyond personal vehicle use, the expressway will significantly reduce used car transport costs between Delhi and Mumbai. Currently, transporting a car by road between the two cities takes 2-3 days via transport trucks navigating the old NH48 route. On the new expressway, the same journey takes approximately 12-15 hours for a truck. This means faster, cheaper, and lower-risk vehicle transport between the two largest used car markets in India. Dealers and private sellers who use transport services to move cars between cities will benefit from meaningfully lower logistics costs once the full expressway opens.
