The Outer Ring Road , abbreviated ORR , also State Highway 234 , is a ring road around the metropolitan area of Chennai (CMA) in Tamil Nadu in India .
The planned length of the road is 62.6 km, of which only 1 km has not yet been built. The Outer Ring Road connects the Grand Southern Trunk Road (NH 45) leading to Tiruchirappalli in the south of Chennai with the Tiruvottiyur – Ponneri – Panchetty Road (TPP) in the north of the city. The ORR leads heavy traffic around the city on the north-south axis, thereby relieving the center of Chennai from through traffic.

The first section was the 29.65 km long southern part between the NH 45 and the NH 205 , the second section was the approximately 30 km long section between the NH 205 and the TPP. The country needs the road is 545.08 hectares , the construction costs amount to 20 trillion Rs (380 million US dollars ).
