Tunga Bridge in Thirthahalli, Karnataka, India, is one of the oldest bridges across the Tunga River.

This bridge is over 75 years old and it was designed by, and built under supervision of, Bharat Ratna Sir M. Visvesvaraya. The bridge connects the area Kuruvalli with Thirthahalli. Tunga Bridge is also called Jayachamarajendra Bridge.

The Tunga Bridge draws many visitors, especially on weekends to see the uniqueness of the bridge.

This bridge has an arc-like structure at the top which is supported by consecutive pillars on either side of the bridge. There are beam-like structures on the top, connecting the two arcs, appearing as a roof. This unique bridge resembles the Sydney Harbour Bridge but with a slight difference.

The bridge was completed in 1943, and inaugurated by H. H. Jayachamarajendra Wadiyar, then the Maharaja of Mysore, and also named after him.
