India’s Highway Boom Has a Second Face: Why Some Roads and Expressways Are Deteriorating
India’s highway network has expanded rapidly over the past decade, bringing new expressways, wider national highways and faster connections between cities. But there is another side to this infrastructure story: road quality can deteriorate quickly when maintenance, drainage, construction quality and monitoring fail to keep pace with expansion.
The issue is significant enough that the government is now putting greater emphasis on maintenance and technology-based monitoring. In June 2026, the National Highways Authority of India (NHAI) announced mechanised drainage cleaning, automated pothole-repair systems and advanced road-sweeping equipment for National Highways and Expressways. The authority has also begun moving towards predictive asset management, designed to identify deterioration before it becomes a larger problem.
So, the story is no longer simply about how many kilometres India builds. It is increasingly about how well those kilometres perform after construction.
India Is Building Roads at a Large Scale
The government's 2025-26 Output and Outcome Monitoring Framework set a target of constructing 10,000 km of National Highways during the financial year, alongside a target of 5,800 km of operational high-speed corridors.
That scale creates a simple but important challenge: every newly constructed road eventually becomes an asset that has to be maintained.
Road construction is therefore only the first part of the infrastructure cycle.
After a highway opens, its pavement experiences heavy trucks, buses, cars, temperature changes, rainfall and repeated loading. Drainage systems also have to keep working. If water enters or remains around the pavement structure, deterioration can accelerate.
This is why a highway that looks excellent shortly after opening can still develop serious problems later if maintenance is delayed.
The Real Problem Is Often Bigger Than Potholes
When motorists see a damaged highway, potholes are usually the most visible symptom. But the underlying issue can involve several factors.
Poor Drainage
Water is one of the biggest enemies of road infrastructure.
In July 2026, NHAI reported a road-surface cave-in on the Delhi-Dehradun Economic Corridor following rainfall. The authority attributed the incident to localised water stagnation along with constraints related to commissioning the permanent cross-drainage system at that location. The affected portion was subsequently repaired.
The incident illustrates why drainage should be treated as part of highway engineering rather than an afterthought.
Delayed Periodic Renewal
Routine repairs can keep a road operational, but they are not always a substitute for larger periodic renewal.
A CAG audit found an example on an NH stretch in Tamil Nadu where periodic renewal of the entire stretch had not been undertaken for years, while routine maintenance and repair work continued. The audit linked the absence of proper renewal to poor riding quality and maintenance concerns.
This distinction matters for taxpayers and toll-paying motorists. Filling potholes may address an immediate defect, but resurfacing or structural rehabilitation may be necessary when an asset has reached a more advanced stage of deterioration.
Construction Quality Can Decide How Long a Road Lasts
The second face of highway development is not only about maintenance. The quality of construction itself determines future maintenance requirements.
A CAG performance audit of road development in Madhya Pradesh found instances where bitumen for flexible pavement works was procured from private vendors despite departmental instructions requiring procurement from public-sector oil refineries. The audit said the department did not adequately verify invoices and that the absence of quality checks created a risk to the quality of bituminous work.
This is an important lesson for the broader highway ecosystem.
A road built with inadequate quality control can require repairs earlier than expected. That increases costs for contractors, authorities and ultimately the public.
Government Is Moving Toward Predictive Maintenance
One of the more important developments in 2026 is NHAI's move away from relying primarily on reactive maintenance.
Under the new predictive asset management approach, NHAI wants deterioration to be identified earlier so that intervention can happen before a minor defect becomes a major failure. The authority says the approach is based on large-scale asset-condition monitoring and technology-driven maintenance.
This is a meaningful shift in thinking.
Instead of waiting for motorists to report potholes or for visible damage to become severe, road authorities can increasingly use data to identify sections requiring intervention.
That can potentially reduce long-term maintenance costs and improve road availability.
AI and Survey Vehicles Are Changing Highway Monitoring
Technology is becoming another important part of the solution.
NHAI announced in March 2026 that it would deploy AI-powered dashcam analytics across around 40,000 km of the National Highway network. Route Patrol Vehicles equipped with dashboard cameras are intended to conduct weekly surveys and use imagery and video data for road-condition assessment.
In June, the government also highlighted Network Survey Vehicles equipped with 3D laser-based systems, GPS and advanced imaging to detect issues such as cracks, potholes and unevenness.
The significance is bigger than simply replacing manual inspections.
A digital record can help authorities identify where a road is deteriorating, compare conditions over time and prioritise maintenance spending.
For a network as large as India's, that could become increasingly important.
Why Monsoon Exposes Weak Roads
The monsoon is often the real stress test for highway infrastructure.
Heavy rainfall can expose weak drainage, damaged shoulders, slope instability and pavement defects that may not be obvious during dry weather.
The Ministry of Road Transport and Highways has therefore repeatedly emphasised monsoon preparedness, including drainage management, slope protection, preventive maintenance and rapid-response mechanisms.
This also explains why a road's quality should not be judged only by its appearance when it opens.
The more useful question is: How does it perform after several monsoons and years of heavy traffic?
More Highways Also Mean a Bigger Maintenance Bill
India's infrastructure strategy has naturally focused on construction because new roads improve connectivity and economic activity.
But every additional kilometre eventually becomes an asset requiring inspection, resurfacing, repairs, drainage maintenance, safety upgrades and emergency response.
The Ministry allocated ₹700 crore to NHAI for maintenance and repairs of National Highways in 2025-26, within a broader maintenance-and-repairs budget framework. The ministry's documents also show a much larger overall budget provision under the maintenance and repairs scheme.
This highlights an often-overlooked point: the economic value of a highway depends not only on construction but also on asset management over its useful life.
What Does This Mean for Infrastructure Investors?
For investors tracking India's infrastructure theme, the changing focus creates both opportunities and risks.
Companies involved in road construction could benefit from continued government spending, but the industry is becoming more focused on lifecycle performance.
The next phase of opportunity may therefore extend beyond new road construction into:
- Highway maintenance
- Asset management
- Road-condition monitoring
- Digital infrastructure
- Automated repair equipment
- Drainage and slope protection
- Road-safety systems
- Operations and maintenance services
NHAI's National Highways Infra Trust (NHIT) is another example of the shift toward professional asset management. In July 2026, NHAI said NHIT manages 2,653 km of highway assets, with professional General Management Consultants being brought in for O&M management of 908 km in the first phase.
For investors, however, individual companies should be evaluated on their financial performance, order book, execution capability, debt, cash flows and contract structure rather than simply assuming that every infrastructure company will benefit equally.
The Bigger Question: Build More or Maintain Better?
India does not have to choose between building new highways and maintaining existing ones. Both are necessary.
New expressways can reduce travel times, improve logistics and connect economic centres. But their value diminishes if existing assets are allowed to deteriorate.
The better infrastructure model is a complete lifecycle approach:
Plan → Build → Monitor → Maintain → Renew → Upgrade
That is where predictive maintenance, AI-based monitoring and automated repair systems could become important.
The government itself is now signalling this transition. NHAI's recent measures combine preventive maintenance, mechanisation, technology-based monitoring and stricter enforcement of contractual obligations.
What Should Be Watched Next?
The real test will not be another announcement about road construction.
It will be whether India's highways remain in good condition five, ten or fifteen years after construction.
Investors, policymakers and commuters should watch:
- Frequency of pavement repairs
- Highway riding quality after monsoons
- Drainage performance
- Periodic resurfacing and renewal
- Contractor maintenance obligations
- Use of AI and Network Survey Vehicles
- Road-safety improvements
- Maintenance spending versus asset deterioration
- Performance of operational highway assets
A highway that opens quickly but requires repeated major repairs is not necessarily a successful infrastructure investment.
Conclusion
India's highway expansion is an important part of the country's economic growth story, but the second face of development is asset quality.
Potholes, pavement deterioration, drainage failures and delayed renewal show why building more kilometres cannot be the only measure of progress. Recent NHAI initiatives on predictive maintenance, AI-powered monitoring, mechanised pothole repair and Network Survey Vehicles suggest that the government is increasingly focusing on what happens after the road is built.
The key takeaway is simple: India's next highway challenge is not just construction speed—it is durability.
For commuters, that means safer and smoother roads. For taxpayers, it means better use of infrastructure spending. And for investors, it could create a larger long-term market around highway maintenance, technology and asset management.
