The Highways Department has completed widening and strengthening of the road running along the left bank of the Cauvery river. The project was executed under the Comprehensive Road Infrastructure Development Programme at an estimate of Rs 39.50 crore.
The Grand Anicut can be reached from Tiruchi off Tiruchi-Chennai Bypass Road, within a few minutes as the distance is just about 12.5 km. The narrow road had largely remained underutilised as it was in a poor condition. Visitors to Grand Anicut had either go via Thanjavur or Vengur near Tiruverumbur. The road has been widened to a width of 10.5 metres from 5.5 metres.
