Chennai (Metro Rail News): Last week, RITES Ltd. emerged as the lowest bidder to draft a Detailed Project Report (DPR) for Chennai Metro‘s new line that will link Koyambedu with Avadi.
This new elevated corridor will branch off from the 44.6 km long Line 5 (Madhavaram – Sholinganallur) which is part of the 116.1 km Phase 2 project. This new line will cover a total distance of 16.07 km and traverse through Thirumangalam, Mugappair and Ambattur.

In February 2024, Chennai Metro Rail Limited (CMRL) issued a call for bids to appoint the DPR consultant for this new Line, setting a 180-day deadline without disclosing the estimated cost.
In April 2024, CMRL opened the technical bids, revealing six bidders. During the evaluation, CMRL disqualified AECOM India – URS Scott Wilson India JV’s bid for non-compliance with the tender conditions.
L&T Infrastructure Engineering prepared the line’s detailed feasibility report in mid-2023, estimating the construction cost, with 15 planned elevated stations, at Rs. 6376.18 crore.
Firm | Bid Value |
RITES | 0.95 crore |
Balaji RailRoad Systems | 1.04 crore |
SYSTRA MVA Consulting | 1.15 crore |
Aarvee Associates | 1.26 crore |
Urban Mass Transit Company | 1.82 crore |
The DPR will shed light on the key aspects of the line, including its length, stations (including underground, elevated, and at-grade sections), route composition, station locations, depot, coach requirements, ridership projections, operational strategies, total cost estimation, and other crucial factors.
Chennai Metro Phase 2
The Tamil Nadu government greenlit the Chennai Metro Phase 2 project in April 2019. It features three new lines covering 116.1 km. In December 2018, RITES finalized the Detailed Project Report (DPR) for Phase 2. Chennai Metro Phase 2 is likely to be ready by 2026. With Phase 2 expected to be fully operational around 2030, Chennai’s metro network will expand to roughly 173 km in length.
