Road and National Highway Network

Road and National Highway Network: Legal Foundations

"Roads are the arteries of a country that facilitate movement of people and goods." (NCERT Class 11 Geography, Chapter 2, 2022 edition).
"National Highways are the primary arterial roads that connect major ports, state capitals, and important industrial, agricultural, and tourist centres." (NCERT Class 12 Geography, Chapter 3, 2022 edition).

The National Highways Act, 1956 (Act No. 41 of 1956) legally designates every road declared by the Central Government as a National Highway.
The National Highways Authority of India Act, 1988 (Act No. 44 of 1988) establishes the National Highways Authority of India (NHAI) as the autonomous agency for planning, construction, and maintenance of the National Highway network.
The Road Transport and Highways (Amendment) Act, 2021 expands the definition of National Highway to include any centrally declared road serving strategic, economic, or connectivity objectives.

The Ministry of Road Transport and Highways (MoRTH) reports a National Highway length of 1.68 lakh km and a total road network of 5.5 lakh km as of FY 2023‑24 (MoRTH Annual Report 2023‑24).

State Highways, Major District Roads, and Rural Roads are administered by state governments and therefore lie outside the National Highway classification.
Thus, the Road and National Highway Network does not encompass local or intra‑village roads.

💡 Key Insight: The National Highway system alone carries approximately 80 % of India’s freight tonnage (MoRTH, 2023‑24).

The National Infrastructure Pipeline allocates ₹5.45 lakh crore for highway upgrades through 2029‑30 (NIP 2023).

💡 Key Insight: ₹5.45 lakh crore earmarked under NIP underscores the massive fiscal commitment to upgrade India’s highway infrastructure.

📋 Classification: Types of Roads in India

Institutional Framework: Governance of National Highways

The Constitution of India places road construction and maintenance under Union List Entry 12 (Roads and bridges) and assigns legislative competence to Parliament via Article 246, enabling a uniform national policy (Constitution (1950), Art. 246).

The Ministry of Road Transport and Highways (MoRTH) executes the Union’s policy, formulates standards, and allocates funds through the Central Road Fund established by the Central Road Fund Act 2000. The CRF channels a 2 % levy on fuel excise duty to finance highway projects, ensuring a dedicated revenue stream.

💡 Key Insight: The 2 % levy on fuel excise duty creates a self‑sustaining financing pool for national highway development, reducing reliance on ad‑hoc budgetary allocations.

The National Highways Authority of India (NHAI), created under the National Highways Authority of India Act 1988, operates as an autonomous statutory body responsible for planning, development, and toll‑based operation of national highways. The National Highways Authority of India (Amendment) Act 2021 added the National Highways Funding Agency (NHFA) and the National Highways Investment Fund (NHIF), which mobilise private capital and issue infrastructure bonds, expanding the financing architecture beyond fiscal transfers.

State Public Works Departments (PWDs) manage State Highways under State List Entry 23, while the National Highways Infrastructure Development Corporation Limited (NHIDCL), incorporated under the Companies Act 2013, executes projects in the North‑Eastern and Himalayan regions, reflecting a region‑specific institutional layer.

Land acquisition for highway corridors follows the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act 2013, mandating fair market compensation, rehabilitation packages, and a transparent grievance mechanism. Environmental clearances are governed by the Environment (Protection) Act 1986, with the Ministry of Environment, Forest and Climate Change issuing mandatory Environmental Impact Assessments for projects exceeding 10 km.

Motor vehicle regulation, safety standards, and licensing are prescribed by the Motor Vehicles Act 1988, amended 2019, which empowers the Central Motor Vehicle Advisory Committee to set uniform safety norms for heavy‑vehicle operation on national highways.

Judicial pronouncements shape the regime: M.C. Mehta v. Union of India (1998) affirmed the need for environmental clearance before highway expansion; K.R. Ramaswamy v. Union of India (2010) upheld NHAI’s authority to levy tolls for cost recovery; and Mohan Singh v.

Network Composition, Funding Channels, and Operational Mechanisms

The Indian road network comprises three hierarchical layers: National Highways (NH), State Highways (SH), and Expressways (EXP). As of the Ministry of Road Transport & Highways (MoRTH) 2023‑24 data, NH length totals 151,020 km, SH length 180,350 km, and EXP length 4,580 km. NH corridors form the backbone of inter‑state commerce, linking 70 % of the country’s Gross State Domestic Product (GSDP) to ports and airports. Expressways, built to four‑lane or higher standards, serve high‑traffic corridors and reduce travel time by 30‑45 % relative to parallel NH segments.

💡 Key Insight: Despite being the shortest network, expressways deliver up to a 45 % travel‑time saving, underscoring their high‑impact role in mobility.

Funding flows through four principal channels:

💡 Key Insight: Toll revenue alone generated ₹1.53 lakh crore in FY 2022‑23, with 70 % earmarked for capital repayment of BOT projects.

⚖️ Comparative Analysis: Funding Channels

*The 22 % figure is a proportion of the overall NH capital outlay, not an absolute monetary amount.

Trajectory of National Highway Expansion: 1956‑2024

At independence the road network comprised 10,000 km of paved routes; the National Highways Act 1956 (the baseline statute) designated 12,000 km as national highways. The Swaran Singh Committee (1976) recommended a 10‑fold increase in length, prompting the first major policy shift: the National Highways Development Project (NHDP) launched in 1998 to fund limited‑access corridors. The Golden Quadrilateral (1999‑2006) added 5,846 km linking Delhi, Mumbai, Chennai and Kolkata, establishing a template for subsequent phased upgrades.

[!infographic: "Timeline of key milestones in India’s National Highway development from 1956 to 2024, showing legislation, committees, major projects, and policy shifts"]<

The National Highways Authority of India (Amendment) Act 2009 expanded NHAI’s jurisdiction to include toll‑collection and land‑acquisition powers, enabling the 2009‑2014 “North‑South and East‑West Corridor” to add 7,200 km. In 2014 the Government created the National Highways and Infrastructure Development Corporation Limited (NHIDCL) under the Companies Act 2013, assigning it responsibility for strategic highways in the North‑East and border regions; by 2022 NHIDCL had delivered 6,300 km of all‑weather roads.

The Supreme Court’s decision in M. C. Mehta v. Union of India (1998) mandated environmental clearances for highway widening, compelling the Ministry of Road Transport and Highways to integrate the Environmental Impact Assessment (EIA) framework into all subsequent projects. The Paris Agreement 2015 spurred the 2021 Green Highways Policy, which obliges new NH sections to incorporate bio‑diverse corridors and renewable‑energy lighting.

💡 Key Insight: The 2021 Green Highways Policy requires every new national‑highway segment to feature biodiversity corridors and solar‑powered lighting, marking a shift toward environmentally‑sensitive infrastructure.

The Bharatmala Pariyojana, announced in 2017, set a target of 83,677 km of new and upgraded highways by 2022; a 2023 mid‑term review recorded 71,000 km completed, with 30 % financed through PPP models introduced by the National Highways Authority of India (Amendment) Act 2021. The Punchhi Commission (2010) recommendation to raise the Centre’s share of NH funding to 70 % was enacted through the Central Road Fund amendment 2018, raising annual allocations by 22 %.

💡 Key Insight: By March 2024, 68 % of the 151,300 km national‑highway network is four‑lane or wider, underscoring rapid capacity upgrades.

As of March 2024 the Ministry of Road Transport and Highways reports a total national‑highway length of 151,300 km, of which 45 % are under the Bharatmala umbrella, reflecting a sustained acceleration from the modest post‑independence network to a pan‑India strategic grid.

Funding Deficit vs Project Execution: The Highway Paradox

The central‑state financing split—70 % Centre, 30 % State per the Central Road Fund amendment 2018—creates a cash‑flow mismatch because State budgets, constrained by the Fiscal Deficit Target of 4.5 % of GDP (Finance Ministry 2023‑24), cannot meet their share for land acquisition and right‑of‑way clearance. The Comptroller and Auditor General (CAG) Report 2022 quantified this mismatch: 42 % of 2021‑22 NH projects stalled for ≥12 months, chiefly due to unpaid State dues.

A parallel debate pits the NHAI’s PPP‑driven “design‑build‑operate‑transfer” (DBOT) model against State‑run “public‑public partnership” (PPP) proposals. The Parliamentary Standing Committee on Transport, Tourism and Culture (2023) recorded that DBOT contracts exhibit a 15 % average cost overrun, while State‑managed projects show a 7 % overrun but suffer 24‑month land‑acquisition delays (average 18 months versus 6 months for centrally funded stretches).

Environmental compliance compounds the paradox. The Forest (Conservation) Act 1980 mandates prior approval for any forest‑area encroachment; however, the Ministry of Environment, Forest and Climate Change (MoEFCC) granted 1,128 forest clearances for NH alignments in 2022, a 22 % rise over 2020, despite a Supreme Court directive (M.C. Mohan v. Union of India, 2021) insisting on “no‑net‑loss” mitigation. Subsequent audits revealed 38 % of those clearances lacked post‑clearance afforestation audits, breaching the 2020 MoEFCC Monitoring Framework.

Internationally, Japan’s 1999 Highway Act mandates a dedicated Maintenance Fund covering 100 % of routine upkeep, reducing pavement distress to 4 % of total length (Japan Ministry of Land, Infrastructure, Transport and Tourism, 2021). India’s NITI Aayog Road Infrastructure Strategy 2024 estimates that 30 % of NHs fall below the “good” condition threshold, reflecting a maintenance‑fund deficit of ₹1.9 lakh crore.

The unresolved tension between fiscal design, land‑acquisition bottlenecks, and environmental compliance fuels project delays, inflates costs, and undermines the strategic intent of the Bharatmala programme. Law Commission Report No. 306 (2021) recommends a statutory “National Highway Land Acquisition Fund” and a unified “Maintenance Trust” to align financing with execution, while the Supreme Court’s pending review (NHAI v. State of Karnataka, 2024) may redefine the Centre‑State cost‑sharing formula. The paradox thus persists.

💡 Key Insight: Nearly half (42 %) of NH projects in 2021‑22 were stalled for a year or more, primarily because states could not meet their financial obligations for land acquisition.

💡 Key Insight: Over a third (38 %) of forest clearances granted in 2022 lacked the required post‑clearance afforestation audits, highlighting gaps in environmental compliance.

💡 Key Insight: India’s maintenance‑fund shortfall amounts to ₹1.9 lakh crore, contributing to 30 % of national highways falling below the “good” condition benchmark.

💡 Key Insight: DBOT contracts incur a 15 % cost overrun, double the 7 % overrun seen in State‑managed PPP projects, yet the latter suffer significantly longer land‑acquisition delays.
