The Tamil Nadu Road Development Company (TNRDC) is preparing a Detailed Project Report (DPR) for the development of an industrial corridor connecting Mannivakkam near Vandalur to Vandavasi in Tiruvannamalai district. This proposed corridor will enhance connectivity to the Cheyyar SIPCOT (State Industries Promotion Corporation of Tamil Nadu) Industrial Complex and the Oragadam Industrial Hub, further strengthening the state’s industrial growth.

TNRDC has suggested upgrading State Highway-116, which runs from Kancheepuram to Vandavasi, into a six-lane road. The Cheyyar SIPCOT complex, which spans across nearly 3,000 acres, comprises Phase I and II, established in 2006 and 2015, respectively. The state government has sanctioned the acquisition of 3,174 acres for Phase III of the complex, expected to cater to growing industrial demand.

The proposed upgrade will improve interconnectivity among several industrial parks in the region, with SIPCOT requesting enhanced road access to handle the surge in traffic as industries expand. Upon completion, the Cheyyar SIPCOT Phase III will strengthen the region’s industrial infrastructure and attract more investments.
