The National Highways Authority of India (NHAI) has decided to prioritise constructing service roads over an elevated corridor to decongest the Trichy-Thanjavur National Highway (NH). Despite the absence of service roads on the 14.40 km stretch of the Trichy-Thanjavur NH between Palpannai and Thuvakudi for about ten years, the area continues to attract significant investments, including new commercial complexes on both sides of the highway.
The service roads for the 14.4 km stretch are estimated to cost around Rs 5.20 billion, while the elevated corridor proposal was estimated at around Rs 30 billion, involving fund sharing between the state and the Union Government.
