Jawahar Setu, Road bridge in Dehri, India

Jawahar Setu is a road bridge spanning the Son River between Dehri-on-Son and Son Nagar in Bihar state. The structure carries traffic across a substantial distance, forming a key link in the regional road network.

Jawahar Setu was designed and completed in 1963 by principal engineer Shantaram S. Kashyap and built by Gammon India Ltd between 1963 and 1965. It carries the Grand Trunk Road, now NH 2, across the Son River. The parallel Nehru Setu rail bridge dates from 1900.

The bridge takes its name from Jawaharlal Nehru, India's first Prime Minister, and stands as a symbol of post-independence development. When crossing it, travelers witness a piece of modern Indian nation-building reflected in everyday infrastructure.

The bridge accommodates motor vehicles and can become difficult to cross during heavy rains or seasonal flooding. Planning your crossing during drier months is advisable, especially if traveling in larger vehicles.

A parallel railway crossing called Nehru Setu was built as far back as 1900, creating a dual transport corridor. This older neighbor bridge reveals a long history of crossing the river at this location.
