The double-decker elevated corridor between Maduravoyal and Chennai Port is now scheduled for completion in the first half of 2027, according to highway officials. The project, aimed at easing city traffic, is currently under construction.
Originally expected by May 2026, the project faced delays due to factors such as monsoon rains. Monthly review meetings are being conducted to closely monitor progress.
The 19-km corridor starts at Gate 10 of Chennai Port, runs along the Cooum River to Koyambedu, then joins National Highway 4 and extends to Maduravoyal. Large concrete pillars are being erected along the Cooum, with planned height adjustments before the next monsoon.
Implemented by a Mumbai-based company, the project is estimated at Rs 55.7 billion. The National Highways Authority of India (NHAI) is executing the work in four phases: Phase 1 (4.95 km) at Rs 13.89 billion, Phase 2 (5.10 km) at Rs 16.17 billion, Phase 3 (4.49 km) at Rs 12.99 billion, and Phase 4 (6.41 km) at Rs 12.05 billion.
Both central and state governments are involved, with Tamil Nadu providing land acquisition support and necessary approvals. Once operational, the corridor is expected to significantly reduce city congestion and improve cargo movement to and from the port.
