The long-delayed Chennai Port–Maduravoyal elevated corridor project has gained major momentum, with the National Highways Authority of India (NHAI) confirming that construction is progressing rapidly and is expected to be completed by November 2027. The upgraded infrastructure project, now estimated at over ₹3,500 crore, is designed as a double-tier elevated corridor aimed at easing Chennai’s traffic congestion while improving cargo movement to and from Chennai Port.
Stretching approximately 20.9 kilometres, the corridor will connect Chennai Port directly with Maduravoyal on the city’s western edge. Officials said the upper deck will function exclusively as a freight corridor for container trucks travelling to Chennai Port, helping heavy vehicles bypass crowded city roads entirely. The lower deck will cater to regular urban traffic and include 13 entry and exit ramps at key locations including Sivananda Salai, College Road, Spur Tank Road, and Koyambedu.
The project was originally launched in 2010 but was stalled for years due to environmental and alignment disputes before being revived in 2023 following discussions between the Tamil Nadu government, Chennai Port Authority, and NHAI. Officials stated that the redesign into a double-tier structure, along with additional ramps and cable-stayed bridge components, significantly increased the overall project cost.
NHAI authorities also revealed that advanced construction methods are being used to speed up work, including large-scale precast segment production at dedicated casting yards. Construction activity currently continues during both daytime and nighttime hours with support from Chennai traffic police.
Once completed, the corridor is expected to dramatically improve logistics efficiency and increase Chennai Port’s cargo handling capacity from 53 million tonnes annually to nearly 200 million tonnes by 2047, making it one of Tamil Nadu’s most significant infrastructure projects.
