The Chennai Peripheral Ring Road (CPRR) is a 132 km, six-lane, access-controlled expressway designed to connect Ennore Port in the north with Mamallapuram in the south.
It forms a crucial outer orbital corridor linking the major national highways NH 16, NH 32, NH 48, and NH 716, ensuring seamless connectivity between industrial zones, ports, and the Chennai Metropolitan Region.

The CPRR is a flagship infrastructure initiative under the Government of Tamil Nadu aimed at decongesting city traffic, improving freight movement, and enhancing logistics efficiency.
