Mathur Aqueduct, Agricultural aqueduct in Kanyakumari District, India.

The Mathur Aqueduct is a footbridge and water channel in Kanniyakumari district, Tamil Nadu, serving both agriculture and pedestrians. The structure spans above the dry riverbed of the Pahrali River on concrete supports and carries an open channel of irrigation water across the valley.

The aqueduct was begun in 1963 under Tamil Nadu Chief Minister K. Kamaraj as a drought relief measure and fully completed in 1969. It was built to link the Kanian Rock and Kootuvayupparai hills above the Parali river, carrying Pattanamkal canal water from the Pechiparai and Chittar dams through the Kodhayar canal. It cost Rs. 12.90 lakhs and irrigates villages in the Kalkulam and Vilavancode taluks.

The aqueduct is named after Mathoor, the hamlet about 3 km from Thiruvattar where it stands; in Tamil it is also called Thottil Palam, cradle bridge, for the trough slung like a cradle between two hills. It links Kanian Parai and Kootuvayupparai hills, and its water irrigates villages in Vilavancode and Kalkulam taluks.

The structure is reached by access roads and rises noticeably above the valley, which may feel dizzying to some visitors. Sturdy footwear is recommended, as the pathways above the structure can be uneven and the height requires sure-footing.

The open concrete channel of the structure is visible along its entire length, allowing visitors to watch flowing water directly while walking above it. The water moves purely by gravity, following a gentle slope without requiring external pumps or pressure systems.
