Project Overview

The MSRDC Konkan Greenfield Expressway (ME-6) is a proposed 389 km, six-lane access-controlled greenfield highway from Panvel in Navi Mumbai to Patradevi on the Maharashtra–Goa border. It passes through three districts along Maharashtra's scenic Konkan coast. These include:

• Raigad

• Ratnagiri

• Sindhudurg

It will pass through 232 villages across 17 talukas. It will include 41 tunnels, 21 major bridges, and 14 interchanges.

The expressway reflects the extraordinary engineering demands of building an access-controlled expressway through the geologically complex, heavily forested, and monsoon-drenched Western Ghats foothills and Konkan coastal terrain.

Developed by MSRDC, the revised Detailed Project Report was completed in December 2024. Concurrently, it applied for environmental clearance from the Ministry of Environment, Forest and Climate Change (MoEF&CC).

The alignment is currently being reworked to avoid the Western Ghats Eco Sensitive Zone (ESZ) - a critical constraint that requires the expressway to find a route that minimises passage through areas designated as ecologically sensitive. This reworking directly affects the land acquisition process, which cannot be finalised until the alignment is confirmed and approved. 

Technical Specification

Project Background

The Konkan coast of Maharashtra has historically lacked expressway-quality road infrastructure despite being one of India's most scenically important and tourism-rich coastal belts. The existing Mumbai–Goa highway (NH-66) runs through the ghat sections of the Western Ghats, with sections that are prone to monsoon disruption, severe congestion during holiday weekends, and a chronic accident rate driven by the combination of tourist traffic, freight vehicles, and narrow two-lane roads in ghat sections. 

Two distinct infrastructure responses emerged to this problem. The first was the four-laning and improvement of the existing NH-66, a brownfield upgrade executed by NHAI. This improves the existing alignment but does not create a new access-controlled route. The second was the proposal for a brand-new, six-lane greenfield expressway, the MSRDC Konkan Expressway (ME-6), that would run parallel to the coastline, bypass the most difficult ghat sections via tunnels, and provide an access-controlled, high-speed corridor from Panvel to the Goa border. 

The MVA government under CM Uddhav Thackeray first formally proposed the greenfield expressway and tasked MSRDC with preparing the DPR. Two factors significantly complicated the DPR process: 

(1) The Western Ghats Eco Sensitive Zone (ESZ) designations, which constrain alignment choices through the most sensitive biodiversity zones between the coast and the ghat crest; and 

(2) The sheer complexity of tunnelling and bridge engineering required across a 376 km coastal-ghat corridor that receives India's highest monsoon rainfall in several sections. The alignment was submitted to the Government of Maharashtra but required reworking due to ESZ conflicts. 

In December 2024, MSRDC completed the revised DPR. The revised DPR incorporates the ESZ-avoidance alignment changes and finalises the project at 389 km mainline (up from 376 km in the original DPR). MSRDC simultaneously applied for environmental clearance to the MoEF&CC.

Environmental & administrative processes restricted the project’s timeline. The 146 ha of forest land requires approval from the Forest Advisory Committee (FAC) under the Forest Conservation Act. The Western Ghats ESZ clearance involves review by the National Board for Wildlife (NBWL).

Konkan Expressway Current Status

As of June 2026, the Konkan Expressway is still in the pre-construction / planning stage. The land acquisition work has not yet started. Furthermore, the alignment has been reworked to avoid the Western Ghats Eco-Sensitive Zone. There is no official confirmation of the completion date of the expressway.

Stakeholders Details

Konkan Expressway Route

The Konkan Expressway is a 6-lane access-controlled greenfield expressway connecting the Panvel area near Navi Mumbai to Patradevi on the Maharashtra-Goa border. It passes through some key districts along the Konkan Coast, including Raigad, Ratnagiri, and Sindhudurg. 

It covers about 232 villages across 17 taluks, passing through some of the most essential coastal corridors such as Guhagar and Chiplun before reaching the southern end at the Goa border.

The northern terminal at Shahbaj village connects to Package MMC-2 of the Virar–Alibaug Multimodal Corridor (VAMMC), a separate MSRDC project that will create a cross-Mumbai suburban corridor from Virar in north Mumbai to Alibaug in coastal Raigad. 

This means the Konkan Expressway will eventually connect seamlessly to the VAMMC, enabling passengers from Virar, Thane, and the northern Mumbai suburbs to access the Konkan coast and Goa without entering Mumbai's urban core. 

Konkan Expressway Project Cost

The total estimated cost for the Konkan Expressway is not yet disclosed publicly.

Project Scope

The following is the project scope of the Konkan Expressway:

• Design Speed: Up to 120 km/h, aimed at significantly reducing travel time (Mumbai to Goa/Patradevi from 12 hours to 6 hours).
  

• Key Infrastructure Elements: It includes 41 tunnels, 21 major bridges, and 14 interchanges.
  

• Right of Way (RoW): Typically 100 meters.
  

• Environmental Aspects: Elevated sections and tunnels are designed for reduced disruption to forests and biodiversity.

Benefits

The following are the benefits of the project: 

• Improved Connectivity: Provides seamless, high-speed access across Raigad, Ratnagiri, and Sindhudurg districts, linking 232 villages and major towns, and enhancing last-mile connectivity for residents and businesses.
  

• Boost Tourism: Transforms coastal tourism in the Konkan region by making scenic destinations more accessible, attracting more domestic and international visitors, and supporting hospitality, adventure, and eco-tourism sectors.
  

• Drives Economic Growth: The expressway boosts the regional economy through increased trade, logistics efficiency, industrial investment, and real estate development along the corridor.
  

• Decongestion of Existing Highways: Relieves heavy traffic on the existing Mumbai-Goa National Highway (NH-66), reducing bottlenecks, accidents, and maintenance costs on the older route.
  

• Long-Term Sustainability Gains: The project consists of tunnels and elevated sections to minimize land disruption, supporting better planned eco-sensitive development compared to unplanned road expansion. 

Conclusion

The Konkan Expressway is a transformative infrastructure project for Maharashtra's Coastal Region, improving connectivity between the southern & the northern points, along the coast. By providing a high-speed, access-controlled corridor that shortens travel times, reduces logistic costs, and bypasses constrained coastal routes, the expressway drives tourism growth, stimulates industrial and port-linked investments, and strengthens integration of the Konkan belt with Pune, Mumbai, and national markets. 

Focusing on the environmental measures, the expressway is designed with robust mitigation measures and compensatory afforestation to minimize habitat fragmentation, manage slope and drainage risks in the Western Ghats fringe, and ensure long-term ecological sustainability. 

Overall, the Konkan Greenfield Expressway can become a durable catalyst for balanced regional development. It will unlock economic potential across the Konkan while setting a benchmark for sustainable, climate-resilient expressway development in India.
