The National Highways Authority of India (NHAI) has taken up the road project between Perambalur and Thanjavur via Ariyalur at a cost of Rs. 157cr. The road is likely to be upgraded and widened ahead of schedule involving strengthening of 66 km length from existing 7 metres to 10 metres. Since it was found that the existing alignment was good enough for widening, it had been retained except a few minor deviations at some places. However, it will execute the project through the State National Highway wing. The road will have paved shoulder to provide adequate space for ongoing and upcoming vehicles. There is no problem on land acquisition as the process has almost been completed. The project should be completed by September 2017.
