Chamravattom Regulator-cum-Bridge, Dual-purpose bridge in Malappuram district, Kerala, India.

The Chamravattom structure crosses the Bharathapuzha River with a roadway while functioning as a water regulator. It consists of multiple openings arranged to allow both traffic and water management across the waterway.

The project was conceived by M. P. Gangadharan, irrigation minister from 1982 to 1986, and Chief Minister K. Karunakaran laid its foundation stone on 17 February 1984. Revived through the efforts of Ponnani representative Paloli Mohammed Kutty, work was inaugurated by Chief Minister V. S. Achuthanandan on 13 August 2009. The bridge opened to the public on 17 May 2012, inaugurated by Chief Minister Oommen Chandy.

The project was the idea of M. P. Gangadharan, irrigation minister from 1982 to 1986, and was revived through the efforts of Paloli Mohammed Kutty, the representative from Ponnani. Local people held their own opening on 6 March 2011, walking across the bridge before its official inauguration.

The best time to cross is during stable weather, as the structure may be closed during flood conditions. Visitors should stay on the roadway and follow any notices related to water control activities on the river.

The regulator has 70 shutters driven by 70 motors on a platform, built to hold water 13 km upstream and block saltwater from the sea. Leakage beneath the shutters left storage a dream, and the IIT Delhi report concluded the structure works only as a bridge.
