CHENNAI: The four-lane elevated corridor between Tiruvanmiyur and Uthandi along the East Coast Road (ECR) is taking shape, with the Tamil Nadu State Highways Authority (TANSHA) inviting international competitive bids for the construction of the stretch under the hybrid annuity mode.
The 15-km elevated stretch, beginning at Tidel Park junction and ending at Uthandi, is aimed at easing traffic congestion and cutting down travel time on the busy corridor. At present, motorists have to cross 17 congested traffic signals on this stretch, taking between 45 minutes and an hour to cover the distance. Once completed, the elevated road is expected to reduce travel time to around 20 minutes.
The project, which is estimated to cost Rs 2,100 crore, will be the first one to be undertaken by the newly formed Tamil Nadu State Highways Authority.
The corridor will pass through key junctions, including LB Road, Kottivakkam, Neelankarai, Injambakkam, and Akkarai. To serve local commuters, entry and exit ramps will be provided at LB Road junction, Tiruvanmiyur RTO office, Neelankarai, Injambakkam, and Akkarai.
Officials said that the stretch currently carries around 69,000 vehicles per day. Despite road widening, congestion persists due to the large number of vehicles and 347 minor roads feeding into the highway.
The elevated corridor, they said, would provide a long-term solution without requiring additional land acquisition, except for portions already earmarked for six-laning works.
The announcement was made as part of the 2025-26 State Budget.
