NHAI suspends toll on Kanpur Lucknow Expressway after road sinks
Source:india-today ↗
Why It Matters
The incident highlights the challenges in public-private partnership (PPP) models like HAM, specifically regarding construction quality, infrastructure resilience to weather events, and governance in large-scale infrastructure projects. This is highly relevant for GS3 Infrastructure and Investment Models.
Summary
The National Highways Authority of India (NHAI) suspended toll operations on the recently opened Kanpur-Lucknow Expressway following the sinking of a road section in Unnao due to rainfall. The expressway, a ₹4,700-crore project constructed under the Hybrid Annuity Model (HAM) by PNC Infratech, faces scrutiny over construction quality. Repair efforts are underway, and a technical investigation will determine the cause before toll collection resumes.
Key Points
- NHAI suspended toll collection on the newly opened Kanpur-Lucknow Expressway after a section of the road in Unnao sank due to recent rains.
- The ₹4,700-crore, 63-km expressway project is being constructed by PNC Infratech under the Hybrid Annuity Model (HAM).
- The incident has raised significant concerns regarding the quality of materials used and the structural integrity of the project.
- Toll collection will remain suspended until repair works are completed, and a technical team is scheduled to investigate the causes of the slippage.
Important Terms
Hybrid Annuity Model (HAM)
A public-private partnership model in highway construction where the government pays 40% of the project cost during construction, and the remaining 60% is paid as variable annuities to the developer based on performance during the operations phase.
UPSC context
GS Paper III (Investment Models). Tests knowledge of PPP frameworks, risk allocation, and methods to revive private investment in infrastructure.
National Highways Authority of India (NHAI)
An autonomous statutory agency under the Ministry of Road Transport and Highways, established in 1988. It is responsible for the development, maintenance, and management of India's national highways network, including toll collection and implementing infrastructure projects.
UPSC context
GS Paper II (Statutory Bodies) & GS III (Infrastructure). Important for evaluating government execution capacity in mega highway projects.
Kanpur-Lucknow Expressway
A 63-km access-controlled expressway (National Expressway 6) connecting Kanpur and Lucknow. Built under the Hybrid Annuity Model, it aims to reduce travel time and foster regional economic growth as a startup and industrial corridor in Uttar Pradesh.
UPSC context
GS Paper III (Infrastructure). Serves as a case study for modern highway development, project execution challenges, and regional connectivity improvements.
Prelims Trap
Under HAM, the private developer bears the traffic risk and recovers costs directly through toll collection.
In HAM, NHAI assumes the traffic/revenue risk. The private developer builds the road and gets repaid via fixed government annuities, shielding them from low traffic volume.
Static Concepts Connected
What is the Hybrid Annuity Model (HAM) for infrastructure?
- Funding split: The government pays 40% of the project cost as construction support linked to milestones. The developer arranges the remaining 60%.
- Risk allocation: Traffic revenue risk is borne by the government (NHAI), while construction and maintenance risks stay with the private developer.
- Payment mechanism: The developer recovers its 60% investment through guaranteed bi-annual annuity payments from the government post-completion.
How is the National Highways Authority of India (NHAI) structured and funded?
- Statutory status: It is an autonomous statutory body created under the NHAI Act, 1988, operating under the Ministry of Road Transport and Highways.
- Core funding: Primarily funded through the Central Road and Infrastructure Fund (CRIF) cess, toll revenues, and asset monetization (InvITs), not direct foreign assistance.

HAM and Asset Monetization (TOT)
Once a HAM project is operational, NHAI assumes toll collection. It can then monetize these toll revenues using the Toll-Operate-Transfer (TOT) model or InvITs to fund new pipelines.
