Road Transportation: Network, Investment, and Policy
3.1 Road Network Overview
Rajasthan has the largest road network by total length among Indian states, with 3,17,121 km as of 2024-25. The state's large geographic area (3,42,239 sq. km — 10.4% of India's land mass) necessitates an extensive network connecting dispersed rural settlements across arid terrain.
Road classification:
| Category | Length (km) | Implementing Agency |
|---|---|---|
| National Highways (NH) | 10,790 | NHAI / MoRTH |
| State Highways (SH) | 17,376 | PWD Rajasthan |
| Major District Roads (MDR) | 13,502 | PWD / RSRDC |
| Other District Roads (ODR) | 30,553 | PWD |
| Village Roads / Rural Roads | ~2,45,000 | PMGSY / PMGSY-III |
| Total | 3,17,121 |

Road density: Rajasthan's road density per 100 sq. km is lower than eastern states due to its vast geography, but investment per km of network is rising steeply.
3.2 National Highways and Expressways
NH 10,790 km places Rajasthan among the top five states by NH network length. Key National Highways:
- NH-48 (Delhi-Mumbai Expressway / DMIC corridor): Alwar–Dausa–Jaipur–Ajmer–Kishangarh–Udaipur–Ahmedabad; among India's busiest freight corridors
- NH-58 (Jaipur-Agra): Connects Rajasthan to UP and the Golden Quadrilateral
- NH-52 (Jaipur-Bikaner): Links state capital to northwest Rajasthan
- NH-11 (Bikaner-Agra): Passes through Shekhawati (Sikar-Jhunjhunu) region
Delhi-Mumbai Expressway (NH-148N) is a landmark project for Rajasthan:
- Total length: 1,386 km; Rajasthan section: ~390 km through Alwar, Dausa, Kota, Chittorgarh
- 6–8 lane configuration enabling 120 km/h travel; reduces Delhi-Mumbai journey from ~24 hrs to ~12 hrs
- Expected completion: 2025-26; valued at ~₹20,000 crore (Rajasthan section)
Rajasthan Expressway Authority is developing greenfield expressways including the Jaipur–Jodhpur–Barmer corridor targeting freight movement for port connectivity.
3.3 Rural Roads: PMGSY and State Programs
PMGSY-III (Pradhan Mantri Gram Sadak Yojana Phase III) is the primary rural connectivity instrument:
- Rajasthan progress: 8,249.40 km upgraded at a cost of ₹3,619.67 crore
- Targets all-weather connectivity to habitations with 100+ population
- Rajasthan's dispersed dhani pattern makes this particularly challenging and important
State road investment over five years (2020-25): more than ₹60,000 crore covering construction, widening, strengthening, and maintenance. Budget allocation for 2024-25: ₹11,986 crore for NH projects (state share), SH improvement, MDR upgradation, and PMGSY connectivity.
3.4 Rajasthan State Road Development and Construction Corporation (RSRDC)
RSRDC is the state PSU executing major road projects. Key functions:
- Executes state-funded road projects (NH state share, SH expansion)
- Implements BOT and Hybrid Annuity Model (HAM) highway projects
- Partners with NHAI for land acquisition coordination on National Highways
- Issues tenders and manages quality of major road construction
- Collects toll revenue on state toll roads
RSRDC has developed key corridors including the Jaipur Ring Road (outer and inner), Jaipur–Ajmer four-lane (NH-48), and Kotputli–Dausa–Jaipur approaches.
3.5 Urban Roads and Smart City Corridors
Jaipur, Kota, Ajmer, and Udaipur — selected under the Smart Cities Mission (2015) — have developed area-based development (ABD) zones with integrated road, drainage, and utility improvements. Jaipur Smart City investments include:
- Junction upgradation of 140+ km within the ABD zone
- City-wide ITMS (Intelligent Traffic Management System) at 350+ intersections
