The inauguration of the Ganga Expressway by Prime Minister Narendra Modi has brought renewed focus on India’s expressway pipeline. The 594-km corridor connecting Meerut to Prayagraj is among the largest greenfield projects in the country and reflects the scale at which access-controlled highways are now being developed.
According to the World Bank, infrastructure investment has a positive and measurable impact on GDP growth, with studies highlighting strong multiplier effects on output, productivity, and market connectivity.
In the Indian context, Niti Aayog has stated that infrastructure investment has a multiplier effect of around 2.5–3 times on GDP, meaning every rupee spent on infrastructure can generate up to three rupees in economic output over time.
Scale Of Expansion
India’s expressway network has expanded significantly over the past decade. According to PIB, citing MoRTH data, the length of high-speed corridors has increased by over 3,000 per cent since 2014. From less than 100 km a decade ago, the network now exceeds 3,052 km operational and 27 greenfield expressway and access-controlled corridors spanning about 9,860 km are currently under development.”
Large projects have driven this expansion. The Delhi - Mumbai Expressway, at around 1,386 km, is among the most prominent corridors and connects six states. It is designed as a high-speed route to reduce travel time and improve freight movement across western and northern India.
India’s highway expansion continues at scale. According to the Ministry of Road Transport and Highways (MoRTH), the national highway network has crossed 1.46 lakh km, with a growing share of new construction focused on access-controlled expressways and economic corridors under Bharatmala.
The pipeline is anchored by large projects. The Delhi-Mumbai Expressway spans about 1,386 km, while the Ganga Expressway is 594 km long. Other key corridors include the Mumbai-Nagpur Expressway (701 km), Delhi–Dehradun Expressway (210 km) and the Delhi-Amritsar-Katra Expressway (670 km), based on MoRTH project data.
According to the Nhai, highway construction has remained above 4,500 km annually in recent years, while Bharatmala includes 34,800 km of economic corridors. Urban-linked projects such as the Kanpur–Lucknow Expressway (63 km) are also part of this expanding network.
Logistics Efficiency Gains
Logistics remains a key area of impact for expressway development. According to NITI Aayog, India’s logistics cost is estimated at around 14 per cent of GDP, with a target to reduce it to around 8 per cent through infrastructure improvements.
Speed improvements play a central role. On conventional highways, truck speeds average 25–30 km/h, whereas on expressways they increase to 60-80 km/h, according to MoRTH-linked assessments. Travel time on long routes such as Delhi to Mumbai is expected to reduce from around 24 hours to about 12 hours.
These changes affect operational efficiency across supply chains. Government indicate that improved road infrastructure can result in annual savings of around Rs 2.4 trillion and Rs 4.8 trillion, driven by lower fuel consumption, reduced delays, and improved vehicle utilisation. Additionally, about 35 multimodal logistics parks are planned under Bharatmala to support freight integration.
Fuel Consumption Impact
Fuel savings provide a measurable indicator of efficiency improvements. According to IBEF, the Delhi–Mumbai Expressway is expected to save over 320 million litres of fuel annually once fully operational.
The same estimates indicate a reduction of around 850 million kg of CO₂ emissions per year, linked to improved traffic flow and reduced congestion. These figures are based on projections associated with the expressway’s design and expected usage.
According to the NHAI Annual Report, access-controlled highways reduce stop-and-go traffic and enable steady speeds, which improves fuel efficiency. On long-haul routes, this results in 20–30 per cent lower fuel consumption, particularly for commercial vehicles.
Toll Revenue Trends
Expressways are structured to generate toll revenue over time. According to industry estimates cited by IBEF, the Delhi-Mumbai Expressway is expected to generate Rs 1,000-1,500 crore per month in toll collections once traffic stabilises, making it one of the highest-yielding road assets in the country.
The tolling model itself is also evolving. The government has begun rolling out seamless automatic toll collection systems based on GPS and barrier-free movement, aimed at replacing physical toll plazas. According to MoRTH, this system is expected to enable distance-based tolling, reduce congestion at plazas, and improve efficiency in revenue collection across highways.
At the institutional level, National Highways Authority of India data shows that highway assets under management exceed Rs 10 lakh crore, underlining the scale of investment being supported through toll revenues. With traffic volumes rising on operational corridors and technology-led tolling systems being introduced, collections are expected to become more consistent and leakage-resistant over time.
Real Estate Changes
Expressway development is increasingly influencing land use patterns along major corridors. According to National Industrial Corridor Development Corporation, the Delhi-Mumbai Industrial Corridor spans about 1,500 km and includes plans for over 24 industrial nodes, driving demand for industrial and logistics land across states.
This impact is most visible near interchanges and connectivity hubs. Industry estimates by Anarock and Knight Frank indicate that land prices along key corridors, including the Yamuna Expressway and the Delhi–Mumbai belt, have risen by 20–80 per cent in select stretches, particularly around high-access nodes and upcoming infrastructure projects.
The increase in demand has also translated into supply expansion. According to Knight Frank, India’s warehousing stock has crossed 500–550 million sq ft in 2025, with a significant share concentrated along highway and expressway corridors, reflecting growth in logistics and industrial real estate.
Environmental Cost Data
Environmental impact reflects both efficiency gains and long-term challenges. According to estimates cited by India Brand Equity Foundation, projected fuel savings of around 320 million litres annually on the Delhi–Mumbai Expressway correspond to a reduction of about 850 million kg of CO₂ emissions per year, linked to smoother traffic flow and reduced congestion.
However, a study by The Energy and Resources Institute prepared for the Ministry of Road Transport and Highways indicates that emissions from highways could increase from 123 million tonnes in 2016–17 to about 278 million tonnes by 2030, driven by rising traffic volumes.
This indicates that while access-controlled corridors improve fuel efficiency at the vehicle level, overall emissions are influenced by growth in traffic demand. The long-term environmental impact will depend on factors such as vehicle technology, fuel mix, and the pace of transition towards cleaner mobility.
Economic Activity Effects
Expressway construction and operation contribute to employment and income generation at scale. According to India Brand Equity Foundation, the Delhi–Mumbai Expressway is expected to generate over 50 lakh man-days of employment during construction, while large highway projects typically create thousands of direct and indirect jobs across construction, materials, and services.
At a broader level, the road transport sector plays a significant role in livelihoods. According to Ministry of Road Transport and Highways, the sector contributes around 4.5 per cent to India’s GDP, while India has over 1 crore truck drivers and associated workers engaged in freight movement, reflecting the scale of employment linked to road-based logistics.
Improved connectivity also affects access and regional inclusion. Government assessments indicate that national highways carry nearly 65 per cent of freight traffic, enabling faster movement of goods and better market access. In addition, improved road connectivity reduces travel time and expands access to jobs, healthcare, and education across semi-urban and rural areas, supporting more inclusive economic growth..
India’s expanding expressway network is improving travel time, logistics efficiency, fuel use, and employment. However, rising traffic may increase overall emissions despite efficiency gains, making future outcomes dependent on cleaner mobility as projects like the Ganga Expressway expand connectivity. |
