Which is locally called Thotti Palam, has the distinction of being Asia’s tallest and longest trough bridge. Mathoor Aqueduct is a concrete structure supported by 28 huge pillars, the maximum height of the pillars reaching 115 ft. The trough structure is 7 ft in height, with a width of 7.5 ft. The trough is partly covered with concrete slabs, allowing people to walk on the bridge and to see the water going through the trough. Some of the pillars are set in rocks of the Pahrali river, though some of the pillars are set in hills on either side. Mathoor Aqueduct’s main appeal is the scenic beauty surrounding the bridge. Hills carpeted with trees and enveloped in mist form a beautiful panorama. Far below you can see the river flowing below and coconut palms swaying in the wind. It’s an enchanting sight.
