KNR Constructions Limited (KNRCL) has received a Letter of Acceptance for a major infrastructure project in Tamil Nadu involving the construction of a four-lane elevated corridor along the East Coast Road (ECR). The project, awarded under the Hybrid Annuity Mode (HAM), carries a bid cost of ₹2,163.07 crore.
The elevated corridor will be developed along East Coast Road (SH-49) from design chainage Km 11+480 to Km 11/800 (West Avenue Road) and up to Km 24+780, covering the stretch from Thiruvanmiyur to Uthandi. The project aims to ease traffic congestion and significantly improve connectivity along one of Chennai’s busiest coastal corridors.
Under the Hybrid Annuity Mode (HAM), the government and the private developer share project financing, reducing upfront financial burden while ensuring steady cash flow during the operational phase. The construction period has been fixed at 1,095 days, while the operation period will extend for five years from the Commercial Operation Date (COD).
However, the signing of the Concession Agreement remains subject to the outcome of W.A. No. 284 of 2026 pending before the Madras High Court. This condition will need to be resolved before the final agreement is executed.
