Chennai’s Western Suburbs to Receive Major Connectivity Boost with Approved Metro Line 5B Extension
In a game-changing development for Chennai’s western corridor, the Tamil Nadu government has officially granted in-principle approval for the Chennai Metro Rail Line 5B—a 21.76 km stretch connecting Koyambedu to Pattabiram. The project is estimated at ₹9,928.33 crore and is now being pushed to the Centre for final approval and funding support through bilateral and multilateral financial institutions.
Initially designed to link Koyambedu to Avadi, the corridor was extended to Pattabiram to strengthen connectivity and tap into high-growth zones including the Outer Ring Road and the TIDEL IT Park at Pattabiram—a ₹330 crore tech hub expected to transform North-Western Chennai.
🏗️ Corridor Details: Stations, Route & Design Innovations
The elevated corridor will start from the existing Koyambedu Metro Station and will feature 19 proposed stops, including vital hubs like Ambattur Estate, Avadi Railway Station, Hindu College, and Outer Ring Road. Notably, three locations will feature double-decker flyovers, with the Metro Rail running above an elevated highway.
Key integration points:
- Ambattur OT & Estate Bus Termini
- Avadi Railway Station
- Outer Ring Road connectivity
This setup promises faster intermodal transfers and significant travel time reductions—especially crucial for daily commuters in Ambattur, Pattabiram, Thirumullaivoyal, and Mogappair.
🏢 Impact on Real Estate and Economic Growth
The corridor is expected to catalyze urban development in North-West Chennai—especially near Pattabiram, where the new TIDEL IT Park is already boosting demand for commercial spaces and housing. With better accessibility, property values in surrounding zones are poised to rise, making it an attractive opportunity for both homebuyers and investors.

🚆 Passenger Demand & Construction Timeline
According to Chennai Metro Rail Limited (CMRL), the entire 21.76 km stretch will be elevated, and the project will need around 112 acres of land for viaducts, stations, and depots. Three-coach trains will serve this route, with estimated passenger traffic aligned with CMRL’s feasibility studies.
Once construction begins, CMRL aims to complete the project within three years.
