The Union Cabinet, led by PM Narendra Modi, has approved a major highway expansion project in Tamil Nadu. This project is a crucial part of the larger Madurai–Dhanushkodi Corridor, designed to transform the transit landscape of southern India.
1. Project Overview
- Section: Paramakudi to Ramanathapuram (NH-87).
- Length: 46.7 km.
- Total Capital Cost: ₹1,853.16 Crore (Civil cost: ₹997.63 Cr; Land acquisition: ₹340.94 Cr).
- Model: Hybrid Annuity Mode (HAM)—a mix of EPC (Engineering, Procurement, and Construction) and BOT (Build-Operate-Transfer) where the government pays 40% during construction and the remaining 60% over the concession period.
2. Strategic Connectivity & Multi-Modal Integration
The project acts as a “logistics spine” for the region by connecting major highways and transport hubs:
| Category | Connections |
| National Highways | NH-38, NH-85, NH-36, NH-536, and NH-32. |
| State Highways | SH-47, SH-29, and SH-34. |
| Railway Stations | Madurai and Rameshwaram. |
| Airports | Madurai International Airport. |
| Ports | Pamban and Rameshwaram (Minor Ports). |
3. Key Benefits & Objectives
- Decongestion: The current 2-lane road faces severe bottlenecks in towns like Sathirakudi and Achundanvayal. The 4-laning will reduce travel time significantly (estimated reduction from 120 minutes to 80 minutes).
- Safety: Modern highway standards and dedicated bypasses will reduce accident risks in densely populated urban clusters.
- Tourism Boost: Enhances the pilgrimage route to Rameshwaram (a Char Dham site) and the “Ghost Town” of Dhanushkodi.
- Economic Hubs: Supports the “Blue Economy” by linking coastal trade routes with the industrial interior.
4. Employment Generation
The construction phase is a major job creator for the state:
- Direct Employment: ~8.4 lakh person-days.
- Indirect Employment: ~10.45 lakh person-days.
- Total Impact: Over 18.85 lakh person-days of work created for local labourers and skilled professionals.
5. Contractor Update
As of October 2025, infrastructure major Dilip Buildcon Limited (DBL) has emerged as the L-1 bidder to execute this project under the HAM model.
