Thondamannar Bridge(Tamil: தொண்டைமானாறு பாலம், Thondamanaru Palam ?) is a road and pedestrian bridge on the Jaffna - Point Pedro highway across the Vadamarachchi Lagoon near the Valvettithurai town of the Northern Province, Sri Lanka in Sri Lanka. It was built in 1953 and destroyed in 1985, and rebuilt afterwards in 2004. The Thondamannar Bridge was primarily used as a barrage since the beginning of its construction period to prevent sea water entering the Vadamarachchi Lagoon that serves as a primary water source for several villages in the neighborhood.
