Mathur Hanging Trough Bridge, near Thiruvattar in the District, is an aqueduct that carries irrigation water through a canal between two hills. The canal itself goes above a small river. Built on very high pillars, is one of the biggest aqueducts, both in height and length, in Asia. The view from the middle of the aqueduct of the surrounding hills and vegetation, and the small river flowing down below, is breathtaking.
