Sangupiddy Bridge, Road bridge over Jaffna Lagoon in Kilinochchi and Jaffna districts, Sri Lanka

Sangupiddy Bridge is a two-lane road bridge across the Jaffna Lagoon, linking Sangupiddy in Kilinochchi District to Karaitivu in Jaffna District. It is 288 m long and 7.35 m wide, with a steel girder and steel deck system resting on reinforced cement concrete pile foundations. It carries the A32 Jaffna–Mannar highway.

In July 1932 British colonial planners proposed the Mahadeva Causeway across the shallow lagoon, but fishermen and salt producers opposed it and it was never finished; locals used the partial causeway until the civil war cut it off. After the war, a bridge was planned for the same site. The Atlas bridge ordered from Mabey and Johnson for Panadura was diverted here, Access Engineering built it in eight months, and it opened on 16 January 2011.

The bridge is part of the A32 Jaffna–Mannar highway, and its Tamil name, Sangupiddy, is shared with the village on the Kilinochchi side. Before it opened, the only road link between the Jaffna Peninsula and the mainland was the Elephant Pass route, so the crossing changed everyday travel for residents on both shores.

The bridge provides a continuous roadway for vehicles and pedestrians and remains accessible throughout the year. Visitors should know that crossing the water offers changing views depending on weather and time of day, with light appearing particularly striking at sunrise and sunset.

The steel bridge was originally ordered from the British firm Mabey and Johnson for a flyover at Panadura junction in Colombo, but it was diverted to Sangupiddy instead. Access Engineering erected the seven-span structure in eight months, and it opened on 16 January 2011.
