National Highway 36 (NH 36) is a National Highway in India that starts at Vikravandi and ends at Manamadurai. This highway runs entirely in the state of Tamil Nadu. It has a total length of 334 km.
The highway runs through Panruti, Vadalur Anaikkarai, Kumbakonam, Thanjavur, Pudukkottai, Thiruppathur and Sivagangai.
National Highway 36 (formerly NH 45C), the 164 km long Vikravandi - Kumbakonam - Thanjavur route, has been proposed to be upgraded to a four-laning road. Initially, the project was planned to be constructed as a four-lane road from Vikravandi to Meensurutti, and then as a 'two-lane road with paved shoulder' from Meensurutti to Thanjavur.
This project was implementing as three phase.
On 06 April 2025, Prime Minister Narendra Modi dedicated to the nation the Thanjavur-Cholapuram four-laning highway, a part of National Highway 36.
