Introduction

Chennai’s rapid urbanization has increased the need for strong road infrastructure. One of the major developments in this direction is the Outer Ring Road (ORR) — a six-lane, access-controlled corridor that aims to decongest inner roads while improving intercity and intracity connectivity.

Overview of Outer Ring Road (ORR)

The Outer Ring Road is a 62 km long corridor developed by the Chennai Metropolitan Development Authority (CMDA). The primary purpose of the ORR is to ease the traffic load from central Chennai and to facilitate the smoother movement of freight and passenger vehicles.

🔹 Type: 6-lane expressway

🔹 Length: 62 km

🔹 Phases: Completed in 2 phases

🔹 Connecting Highways: NH-45 (GST Road), NH-4 (Bangalore Highway), NH-205, NH-5 (GNT Road)
