Chennai: The Tamil Nadu State Highway Department is constructing the Chennai Peripheral Ring Road, a 132.87 km, 10-lane expressway connecting Mamallapuram to Kattupally port, in an effort to ease traffic congestion in the city.

Tamil Nadu’s Longest Expressway: Chennai Peripheral Ring Road Nears Completion
The Chennai Peripheral Ring Road will be the fourth ring road in Chennai and is expected to reduce air pollution in the city. Two-wheelers will only be allowed on service roads, not on the main road. Private port companies, including Ennore Kamarajar Port, Kattupalli Adani, and L&T, have urged the Tamil Nadu government to complete the project quickly.
The project’s design speed is 120 km/h, with six main lanes and two service lanes on both sides. The Ennore-Thachur section is currently under construction. The Chennai Peripheral Ring Road is expected to become Tamil Nadu’s first 10-lane road, marking a significant milestone in the state’s infrastructure development.
The project is slated for completion by 2025, with the Tamil Nadu Road Development Corporation overseeing its execution under the Engineering, Procurement, and Construction (EPC) model.
