Some of the culverts built during the British period in the district have been renovated and widened by the Highways Department to facilitate transport of agricultural produce, particularly sugar cane, from Cuddalore and Villupuram districts.
According to official sources, a large number of lorries that transport sugar cane from Veppur, Vadalur and Kattumannarkoil to sugar mills in Tiruchi district pass through the Lalgudi - Perambalur stretch. The British had built a series of five narrow culverts along this stretch. Though they were structurally strong, the culverts were narrow. Hence, they were renovated and widened.
