The 170Km stretch of NH66 between Krishnagiri and Tindivanam is the main connecting route to Tiruvannamalai from Bangalore, Chennai and Pondicherry. This is also the highway used by people coming from other parts of Tamilnadu. It is used daily by thousands of people, from the villages along the route and for inter-state travel. Every month during full-moon around 5-6lakh devotees visit Tiruvannamalai, for making circumambulation (girivalam) of Sacred Hill Arunachala and most of them use NH66 to reach Tiruvannamalai. The Holy Arunachala hill attracts spiritual seekers from across the globe. Several thousand foreign tourists come to Tiruvannamalai every year to visit the Ashram of the great sage Shri Ramana Maharishi and other holy places around the Arunachala hill . They use NH66 for reaching Tiruvannamalai from Bangalore or Chennai Airport. The road condition has been very bad for several years. The road widening project, for making it a 2 lane highway started 2 years back. According to the May 2014 report of NHAI, the 2-laning contract has been awarded to Transstroy India and the project is expected to complete by Sept 2014. Many trees lining the road have been felled, but the work is nowhere near completion and in the last few months there is no sign of any work taking place on this highway. The road condition is so bad with huge pot holes that even the government transport buses use an alternate road wherever possible, like Krishnagiri-Vellore-Polur. Most of the traffic tries to use alternate routes which increase the travel distance by 40-50Kms, making the travel time longer and results in fuel wastage. The government needs to prioritize this project and get it completed quickly.
